This interview with Dr Ashok Johari (ANJ) was conducted in Hotel Le Meredian. The interview was conducted by Dr Sandeep Patwardhan (SP) and Dr Ashok Shyam (AKS) on the second day of Pune Orthopaedic Society Annual Meeting in Pune, India.
The purpose of this interview is to know more about the journey of Dr Ashok Johari who is a pioneer in paediatric orthopaedics in India and in the world. This interview aims to catch a glimpse of his life and times and also showcase the rise of paediatric orthopaedic as an independent faculty in India. A broader objective is to attract people to paediatric orthopaedics and to have pride in our own people who have done exceptionally well in reaching international acclaim in respective fields.

AKS: Let me begin by asking you about your family background. Tell us something about your family and where you grew up?
ANJ: My father, Dr. N.K. Johari was an anaesthetist and my mother was a house wife. I was the only son among four daughters. One of the big aims of my father’s life was that we should be very well educated. He was a disciplined person himself and was particular about our studies and felt that we should do well in our exams. Not necessarily get first rank, but should get good education. He also focussed a lot on our extracurricular activities. One routine which is very interesting, which I would like to share. I had school weekly off on Thursday and my father insisted that I be with him on that day. He would go to different hospitals and take me with him to operation theatres (OT). He would want me to simply watch what is happening. I have these memories right from my age of five when I would stand on stools and watch surgeries in operation theatres from morning to evening. If on Thursday he didn’t have OT, he made sure that I was involved in some or the other work like washing the car, servicing the scooter etc. Everything had to be cleaned in the cars, carburettors had to be removed and cleaned. This helped me learn discipline from an early age.

Dr Ashok Johari

My family was of medium means, though two generation ago we were quite rich. Our family were Jagirdars from Bikaner in Rajasthan. Once the Jagirdari went away, we were jewellers to all the princes of Rajasthan and South India. However somewhere things went wrong and by the time my father was young, most of the wealth had disappeared and my father had to work very hard. So I always had great respect and appreciation for him. He came to Mumbai for medical education and then stayed back here.
I was a sickly child specially bronchitis. Sometimes I used to get status asthamaticus and my father used to give me deriphylline drips, oxygen, everything at home. This also brought me in contact with doctors other than my father and that is the time I decided to become a doctor.

AKS: In fact our next question is on the topic of how did you decide to become a doctor, how did you get the inspiration?
ANJ: My father was my first inspiration. Vising OT’s and watching surgeries over the years developed interest and then being a ‘sick’ child I came into contact with many other doctors. These are the factors that influenced my decision to become a doctor. My father was not very keen on me becoming a doctor. Although he would take me around for cases, but he realised that the profession was degrading in someways and he did not want me to join medicine. I had to literally fight with him to enter medical college. In fact I said that if he did not want to pay the fees, I would raise money but I would definitely go to medical college.
I was in a technical school and from very early in life I had resolved to become a doctor specially influenced by watching surgeons in OT. These surgeons were associated with a lot of ‘Drama’ and glamour which really attracted me. After my 7th standard I had to opt out from normal school to go to a technical school. In our school we had this system of cumulative record. Our whole academic records were entered and we were asked our ambitions in life. Everywhere in my cumulative record my ambition is written as ‘I want to become a doctor and specifically orthopaedic surgeon’, right from my 8th standard. I topped the school and went to Jai Hind College and then entered medical college.

SP: Which medical school did you go for your MBBS.
ANJ: I went to Grant Medical College (GMC), JJ Hospital, Mumbai. I had a sort of connection with GMC from childhood. My father was a honorary professor at GMC and I had frequented the college since a very young age. I liked the campus very much specially the old building. My father was a medical student at GMC in 1940’s. He had clicked tons of photographs of the GMC campus, college buildings and old buildings from that era. We displayed these in an exhibition in 1976 organised by me in GMC called EXPO -76. I used to be the Magazine Editor then. I used to see these pictures in my younger days and had decided that I would go to GMC. So I did my medical school at GMC.

AKS: During medical school were there any influences that helped or formed your career? Why did you choose orthopaedic surgery?
ANJ: As you know I had already decided on orthopaedics long back, especially the drama and the glamour of orthopaedic surgeons attracted me strongly. While in third year of my medical school, when I was scheduled for the orthopaedic posting, Dr Joshipura was our head of department (HOD). On the first day he asked, ‘Who wants to become an orthopaedic surgeon’, and rather naively I raised my hand (laughs). From that day, I had a bullseye marked on my back and was targeted for everything. Dr Joshipura would ask me questions on anatomy, pathology and orthopaedics all the time and would comment ‘You want to be an orthopaedic surgeon and you don’t even know this!’ I realised that it was with a good intention but I really felt pressurised to the extent of mental agony (laughs again). Suddenly something happened and in the middle of my orthopaedic term, Dr Joshipura disappeared. Later we came to know that he had a tussle with the dean. The dean wanted him to come to his office to see a patient and he said that he was on rounds and insisted that the patient be sent to him to be seen after the rounds. On this point there was some argument and he resigned from the college.

AKS: So who would you say, once you started orthopaedics as a registrar, were your early influences?
ANJ: By the time I came back for my residency Dr Taraporewala was the chief of orthopaedic surgery at GMC. But we got a chance to see all the great surgeons including Dr Masalawala. Especially on Saturdays when we had these Saturday departmental conferences at GMC where all people connected to the institution would come. Dr Ugrankar, Dr Kawarana etc and all the unit chiefs along with HOD. This gave us lot of opportunity to interact with these people. Dr Masalawala was at that time very well recognised, he had been the past president of Indian Orthopaedic Association. He was pioneer in tuberculosis of spine and had the largest series of around 400 cases (this was in late 70’s). He published that in Indian Journal of Surgery. These Saturday interactions allowed us to connect with these giants of Orthopaedics in India and learn first-hand from them. I did two terms one in orthopaedic surgery and one in general surgery. For general surgery we always preferred to go to St. George’s Hospital to work under Dr Kumbhani. He was a general surgeon turned orthopaedic surgeon. He was appointed as a general surgeon but did only orthopaedic work. There we would learn general surgery from other surgeons in the unit and do orthopaedic work with Dr Kumbani. In general surgery we got training in abdominal surgeries, appendectomy, hernia repairs and other common procedures which was quite helpful in life even later. Along with that we had advantage to continue doing and learning orthopaedics with Dr Kumbhani.

AKS: You were pioneer in Paediatric Orthopaedics in India? Tell us something about the Story? – Why did you choose it?
ANJ: This is an interesting story and many incidents happened serendipitously for me to land up as a paediatric orthopaedic surgeon. After my two house posts, there was a six month wait for the registrar post and instead of waiting and going back to JJ Hospital, I decided to join the Children’s Orthopaedic Hospital (COH) at Haji Ali, Mumbai. At that time there was this unique personality there, ‘Dr.Perin K Mullaferoze’ who was the HOD at COH. She was an intimidating lady orthopaedic surgeon and was a battle scarred war veteran. She was a Lt. Colonel in the British army and had fought in World War II. She had seen action in Middle East and Unified India which extended till what are now Afghanistan, Pakistan and Bangladesh. She was an authoritarian lady and she was also the HOD of orthopaedics at JJ Hospital prior to Dr Masalawala. She was the second HOD of Orthopaedics in JJ, but she left JJ and concentrated completely on children’s Orthopaedics, specifically cerebral palsy. So in effect she was the first paediatric orthopaedic surgeon in the country but focussed on very limited diseases. She was around 70 years of age when I joined.

AKS: This was in which year Sir?
ANJ: This was in 1980 and I instantly liked working in paediatric orthopaedics. I was very fond of children and used to play with kids. At that time there were lot of polio cases who visited us at COH. Treating polio had a very rational approach – like if we did a particular intervention the outcomes would be as expected. The disease as well as the management could be all very well explained by biomechanics and anatomy. I very much liked this rational – logical approach. I worked there for 6 months as a registrar before I returned back to JJ. I had a very good learning experience with Dr Mullaferoze. She was very particular about certain things like applying plaster. For her, the plasters should be very comfortable to the patient and well padded. She was very good surgically, especially older surgeries of poliomyelitis, arthrodesis etc. By the time I went to COH, she was already in her 70’s and had stopped operating, but we requested her to come to OT and she demonstrated surgeries to us. So my time at COH actually build the resolve in me to pursue paediatric orthopaedics. Although it might be surprising that I had a bioengineering background and was very interested in biomechanics and joint mechanics. I had already done advanced work in tribology and joint replacement. I did summer workshop on tribology at the Harcourt Butler Technological Institute, Kanpur. UGC used to hold this workshop which I attended during 1979. Joint replacement was a good upcoming field but I felt it won’t give me the challenges and the variety which paediatric orthopaedic would give me. Also my aptitude was for paediatric orthopaedics. For example if you see even now, paediatric orthopaedicians are more academically oriented, more studious, and soft spoken. They take their own time to do things, they mix with people, and they mix with children. Ego problems are also not many among paediatric orthopaedic surgeons. To be with children you have to be like children and let go of your ego. So I believe I was much more inclined to be a paediatric orthopaedic surgeon than anything else.

AKS: Did the specialty of paediatric orthopaedics exist in those days in India?
ANJ: No the speciality did not exist in those days, it was all general orthopaedic surgeons who did the paediatric work. COH was specialised in paediatric orthopaedics, started basically to deal with polio. So with polio it started dealing with other children orthopaedic problems. With decline of polio, it started dealing with cerebral plasy (CP) too. It became the first centre in India to deal with CP and one of the foremost in the world. In 1961, Dr Mullaferoze went to USA to study cerebral palsy. There was this PL-480 scheme that funded her. It also funded the setting up of the cerebral palsy centre at COH in1963 by the Americans. So the speciality of paediatric orthopaedics did not really exists in those days, but there were people who did major work in paediatric orthopaedics. But this was not exclusive work and they continued to do adult orthopaedic work too. For example Dr MG Kini, was one of the senior most orthopaedic surgeon who did lot of paediatric work and had published papers on the same. Dr Mullaferoze and Dr Dholakia worked as assistants to Dr Kini at COH. Dr Kini was HOD at Chennai and after his retirement he was invited to be director at COH. He was one of the first qualified orthopaedic surgeons, first to have an orthopaedic degree in India. He went to Liverpool and did his MCH and came back to start practising orthopaedic surgery exclusively. In later years he did a lot of paediatric work but not exclusively.

SP: The Kini Memorial oration at WIROC is dedicated to him
ANJ: Yes correct. He worked in Bombay at COH and when he retired Dr Mullaferoze took over from him as the director. Dr Dholakia was visiting consultant at COH, until he became full time consultant at Bombay Hospital. So the speciality definitely did not exists in those days as we see it today, but I was determined to pursue it. I continued to look for opportunities in paediatric orthopaedics and luckily in 1984, I came across an advertisement in Indian Journal of Orthopaedics (IJO). The advertisement was about a fellowship in paediatric orthopaedics in Japan. Fellowships were unheard of in those days and it was very difficult to get one. I only knew a fellowship in hand surgery in Singapore and a spine fellowships in Hong Kong. Prof. Marwah was HOD of Orthopaedics and Dean at Nagpur GMC and had connections with surgeons in Japan. He was also the President of Indian Orthopaedic Association at that time. A famous Japanese children’s hospital offered a fellowship to Dr Marwah, to send a young person for training to Japan and Dr Marwah placed an advertisement in IJO, which I came across, fortunately! I responded to the fellowship and sent him my CV and by good luck I was selected from a number of applicants. I got a call from Dr Marwah to be ready to go to Japan. Going to Japan was not going to be easy, as I understood that Japanese do not speak English and it was clear to me that I had to learn Japanese. I came to know about the confirmation for fellowship around 9 months before I had to actually leave. I utilised this time to learn Japanese and when I reached Japan, I did an intensive course in Japanese language. This enabled me to converse in Japanese. Writing Japanese was very difficult and takes years to learn but I learnt enough to at least converse with surgeons and patients. I was a lecturer at Sion hospital at that time. I finished my MS in 1981 from JJ and in 1982 I finished my registrarship. In 1982 I got the opportunity to be a tutor at Sion hospital. I was then lecturer at Sion where I would do trauma, spine, paediatric and also arthroscopy. Surprisingly I did lot of arthroscopy at that time. It was I, who actually discovered that Sion hospital has an arthroscope which no public hospital had! I was fooling with our OT sister and rummaging through her cupboard when I found a Karl Storz box and I was told that this was an arthroscopy set ordered by Dr. Pandit. Dr Pandit was the HOD and had retired, so probably the arthroscopy set came after his retirement and nobody knew about it. So I started using the arthroscope and did lot of arthroscopies.
Once I got opportunity to do paediatric orthopaedics in Japan, things started to turn positively toward paediatric orthopaedics. The spectrum of disease in Japan was quite different from that in India. There the focus was on early detection, braces etc. Surgeries were performed but only for different diseases like osteogenesis imperfecta etc unlike the neglected and complex cases that we had in India. But my time in Japan gave me an introduction to paediatric orthopaedic world.

When I came back to Sion Hospital in 1986. my boss, Dr. S.S. Vengsarkar had resigned as HOD and Dr. N.S. Laud had taken over. Both encouraged me a lot. Dr Laud allotted me a side room with six paediatric orthopaedic beds. I told him that I wanted a separate paediatric orthopaedic OPD and he graciously agreed. We started this paediatric orthopaedic OPD in early 1986 and it was the first paediatric orthopaedic unit in any teaching hospital. We interacted with other paediatric faculties also. It was a flourishing OPD and was held every week. Apparently this OPD was later taken over by Joy Patankar later on. During this time in 1986 there was an advertisement for a post in Wadia Children’s Hospital for which I was selected. I had already completed 4 years in Sion by that time and so I decided to leave in 1987. I gave my resignation in February 1987. Dr Dalal who was the dean at Wadia hospital requested me to take up Dr Kumbhani’s OPD. I was not yet relieved from Sion, but I accepted the offer and started attending OPD from October of 1986 till February of 1987. In February I was relieved from Sion and started working at Wadia full time.
Another peculiar thing happened in February of 1987. There was a conference in Mumbai arranged by Dr Dholakia, named ‘Surgery in the Tropics’. Prof. Robert Owen from Liverpool University came for this conference and we were scheduled together for a symposium on Perthes disease on which Dr. Dholakia was also speaking. I was to speak on etiopathogenesis and Prof. Owen was to speak on the surgical aspect. Since I was very interested in paediatric orthopaedic I was continuously reading and before the conference Liverpool group had recently published their work on etiopathogenesis. I went through the paper and prepared my presentation. Prof. Owen thought that no one from India would be knowing about the study and so included some 20 slides of the etiopathogenesis in his surgery lecture, but then he had to rush through them as I had already covered them in my lecture. After the symposium was over, he asked me if I was interested in doing M.Ch at Liverpool. I did want to go to Liverpool but I said I would come only if I got a registrar job which could sustain me. I told him that I can’t come only as a student, pay fees and attend the course. He promised that he will do something and true to his promise he wrote back in 10 days offering me a student position for M.Ch. I again wrote back requesting for a job with the M.Ch. I got a reply from him inviting me for an interview for a job. He said if the interview board decides to give you a job, you can do both M.Ch and the job. In the interview they already had my CV, I had Japan experience and 5 years’ experience at Sion and Wadia hopital. Prof. Owen had retired but attended the interview board. I had opted to stay in YMCA dorm which was near the bus station of Liverpool. After the interview I was returning back to YMCA when somebody followed me and asked me to call on a number. He said Mr John Taylor wanted me to speak to him. Mr John Talylor was senior consultant and was chief of orthopaedic surgery at Alder Hey hospital. When I called him, he invited me for dinner, to which I gladly agreed. He took me to his house and he congratulated me on getting the job. He said this is the first time we are appointing anyone directly from India. We have given you the most prestigious job in Liverpool. I returned back to England in December 1987 to get used to the system. I had very good time at Liverpool. I had alternate day emergency on call and everyday 2 hours classes. This was quite a hectic schedule with almost every other night going on till late with surgeries the next morning and then followed up with OPD. There were classes every day and class assignments too. Fridays’ were totally off to attend M.Ch schedule where we had classes, visits to other hospitals, case presentations, workshops etc. I was seven years post MS and had maturity to grasp most of the things. So these two experiences, in Japan and England added a lot to my understanding. Some things are very different at these places specially their approach to education. For example if I had to use the library at Japan at the Yokohama Children’s Medical Centre(where I did my fellowship), I had to simply ask the keys from the security. I could go to the library anytime and read. If I had to borrow a book, I simply had to write my name in the card and drop in the box and take the book. In UK, if I needed any literature, I would simply ask the librarian and they would provide me with everything. This was unheard of in India at that time and it was extremely difficult to get literature. We had to visit many libraries and beg for articles and many a times they won’t have the article. When in UK, I continued my thesis on septic hip which I had started in India and wanted to make my M.Ch thesis. In India I did not find much literature and so I prepared my classification etc for the same. But in England while referencing and cross referencing I came across an article by Hunka on the topic. It wasn’t very popular article by somewhere in cross-referencing it was mentioned as Hunka’s criteria for septic hip. Then I knew that he had already published a classification in 1982.
The experience at Liverpool was very helpful and I believe a good impression was made of Indian students. I had a good experience already specifically in polio, so if anyone was stuck on some of these rare cases they would call me. Prof Klenerman was a great foot surgeon who worked at our hospital and whenever patients of polio would come to him, he would call me for opinion always. This created a good impression and probably made easy for future guys to join MCh. These experiences helped me a lot in grooming myself into paediatric orthopaedics.

SP: How was the journey when you came back?
ANJ: So I came back to Wadia and also joined COH, JJ Hospital and Asha Parekh hospital as honorary. I juggled all of them for some time but found it quite taxing. I really wanted to be a full timer as I was of academic mind-set, so wanted to remain at an institute. But I found the environment at the Sion and other hospitals not very appealing. For everything we had to literally beg. What should logically follow in terms of education, academics and infrastructure had to go through lot of red tape, through HOD, Dean, AMC etc. This environment I found very frustrating and didn’t think I could spend my whole life in such environment. Meanwhile I had a conversation with Dr Dhir who was HOD at KEM Hospital. I asked him if he will be attending a forthcoming conference to which he replied that he was allowed to attend only two conferences from the corporation. They also were not allowed to buy books directly and had to go through library to buy anything. This strengthened my resolve to come out of the full time mode to join private practice rather reluctantly. I was very fond of reading, learning new things etc but had to give up full time

AKS: Did you ever think of staying back in UK.
ANJ: Somehow I never wanted to stay back in UK. They had good impression of me and would have created an opportunity for me, but I felt a bit misplaced there. Misfit in the sense you have to be always in your best behaviour and use fork and knife etc [laughs]. I always thought I belonged here and I didn’t want to stay there.

When I came back I was just doing honorary job at various places. My wife questioned me on my intentions to continue as honorary at various places and earn paltry honorarium. I used to get around 125 rupees from JJ Hospital, 50 from Wadia, 200 rupees from COH with total of 500 rupees a month. With these pressures I decided to enter private practice and the next part of my journey is about being full-fledged private paediatric orthopaedic surgeon and being involved in promoting the speciality of Paediatric Orthopaedics in India. Its again a very interesting story that involves birth of Paediatric Orthopaedic Society of India (POSI)
We will continue the story further in the part two of the interview, to be published in the forthcoming issue of IJPO

Abstract

Introduction: Vascular access is a vital task in the resuscitation of a critically ill child. Although peripheral intravenous access is the traditional method for gaining vascular access, this can be challenging in patients with circulatory collapse.
Today IOI (Intra Osseous Infusion) is accepted as standard equipment on paediatric and adult rescue carts. IOI is recommended in Advanced Cardiac Life Support and Pediatric Advanced Life Support treatment protocols as alternative means of vascular access in the event that IV cannulation is delayed or not feasible. The conventionally recommended site for IOI is the proximal tibia.
Case Report: We report the case of a 6 month old boy with meningococcal septicaemia who was admitted to ICU for resuscitation that had an attempted intraosseous cannulation in his left leg with intravenous fluids administered in the ambulance en route. On arrival at the hospital, it was noted that the left foot was swollen and tense and an alternative site for administration of fluids was obtained. An orthopaedic review was sought for possible compartment syndrome left foot. Stryker needle measurements of intracompartmental pressures within the foot were elevated. The decision was then made to apply an eschmark bandage to the left foot and lower leg and to elevate the leg for 2-3 minutes with this in place. After removing the eschmark bandage, the intracompartmental pressures were remeasured and found to have returned to acceptable levels.
Conclusion: We believe that if compartment syndrome is being considered because of the clinical examination and/or elevated intracompartmental pressures in patients post IOI, it may be worth employing this technique with the eschmark bandage before proceeding to surgical decompression as this technique is far less invasive than surgical decompression and if successful, as in this case, can lower intracompartmental pressures quite significantly and quickly.

Introduction
Vascular access is a vital task in the resuscitation of a critically ill child.[1,2] Although peripheral intravenous access is the traditional method for gaining vascular access, this can be challenging in patients with circulatory collapse and it has been demonstrated that experienced emergency department personnel can require more than 10 minutes to gain IV access in such cases[3].
Tocantins and O’Neill established in 1941 that the bone marrow cavity of a long bone was a possible site of vascular access and in the 1940s[4] and early 1950s, Intra Osseous Infusions (IOI) were used extensively in children who required repeated blood transfusions and antibiotic therapy[5] IOI has also been shown by radionucleotide technique to deliver fluids as rapidly as intravenous techniques [6] However intraosseous infusion fell out of popularity in the 1950s due to the advent of plastic IV catheters.[5]
Today IOI is accepted as standard equipment on paediatric and adult rescue carts. IOI is recommended in Advanced Cardiac Life Support and Pediatric Advanced Life Support treatment protocols as alternative means of vascular access in the event that IV cannulation is delayed or not feasible.[2,7]
Studies have demonstrated that the use of IOI can decrease the time needed to obtain vascular access in paediatric patients in cardiac arrest.[8,9] and that the rate of vascular access in paediatric cardiac arrest patients is higher for IOI (83%) than for all other forms of IV access.[10]
However, there are potential complications associated with IO infusion and these include osteomyelitis, cellulitis, fracture at IO-line site, compartment syndrome, and fat embolism. [14,15,16,17]
It is the complication of compartment syndrome that we would like to discuss further in this case report.

Case Report
We report the case of a 6 month old boy with meningococcal septicaemia who was admitted to ICU for resuscitation. While in the ambulance on route to the hospital, paramedics had attempted an intraosseous cannulation in the child’s left leg. Uncertainty exists as to whether the cannula was correctly sited but intravenous fluids were administered through this cannula. On arrival at the emergency department, it was noted that the left foot was swollen and tense and an alternative site for administration of fluids was obtained. After resuscitation and admittance to ICU, the orthopaedic team were asked to review the patient with regard to a swollen discoloured left foot. The child was fully intubated and otherwise stable at this stage. On examination, the left foot was swollen and tense to palpation. There was good capillary refill in all the toes and a dorsalis pedis pulse was palpable. It was impossible to assess discomfort or pain in the foot at this stage as the child was fully intubated. As a full clinical examination was not possible due to the clinical condition of the child, it was decided to use a stryker needle to measure intracompartmental pressures within the foot with the intention of determining if there was a case for compartment syndrome in the foot. It is now accepted that there are 9 compartments within the foot[12] The stryker was initially placed perpendicular to the skin at the medial aspect of the foot, at the base of the first metatarsal and only advanced 1cm approx to measure the medial compartment. Once that measurement was taken, the needle was subsequently advanced deeper to measure the pressure within the central compartment. One measurement was taken laterally from the lateral compartment. Due to the small size of the foot and relatively large size of the needle, it was decided against individually measuring the other remaining compartments as there would be multiple large puncture wounds in a relatively small foot. A collective measurement was taken from the dorsal aspect of the foot and we are aware that this may not accurately represent the instrinsic compartments. Initial measurements with the stryker needle revealed that the intracompartmental pressure on the dorsal aspect of the foot was 15mmHg while the pressure on the plantar aspect of the foot (medial, central, lateral) was 37mmHg and this result was confirmed by 2 different individuals independently measuring compartment pressures within the foot. Diastolic blood pressure at the time of measurement of the compartment pressures was 56mmHg.
Compartment Syndrome can be considered when the pressure difference between diastolic blood pressure and intracompartmental pressure is less than 30mmHg or also when absolute interstitial pressure is greater than 30mmHg.
The decision was then made to apply an eschmark bandage to the left foot and lower leg and to elevate the leg for 2-3 minutes with this applied. The reason for attempting this course of action was that we had reasoned that the raised intracomparmental pressure was the direct result of the fluid that had leaked into the soft tissues within the compartment after the administration of fluid through the incorrectly sited IOI cannula and that by applying the eschmark bandage, we may be able to force some of this fluid out of the compartment and back into the vascular system.
Once the eschmark bandage was removed, the intracompartmental pressures within the foot were again measured with the stryker needle. These results revealed an improvement in pressures with the dorsal compartment reading 12mmHg and the pressure recorded on the plantar aspect of the foot (medial, central and lateral compartments) reducing to 21mmHg. The diastolic blood pressure was 58mmHg while these repeat measurements were being taken. This measurements was taken twice to help ensure that they was accurate. Clinically, the foot also looked better and was less tense to palpation. The foot was subsequently elevated and monitored. The foot continued to improve clinically and surgical decompression for compartment syndrome was not necessary.

Discussion
Intra Osseous Infusion is a proven method of delivering urgently needed fluids to a patient and this method of delivery works because the rich vasculature of long bones transports the fluids and medications to the central circulation. Sinusoids within the marrow of long bones function as rigid conduits that do not collapse in the presence of hypovolemia. Blood passes into the venous channels of the medulla and then leaves the bone through nutrient or emissary veins entering the general circulation.
The conventionally recommended site for IOI is the proximal tibia[2] The tibial tuberosity should be located by palpation just below the patella and the recommended insertion site is the relatively flat area approximately 2cm distally and slightly medial to the tibial tuberosity. Although this site is usually distal to the growth plate, it is still recommended that the needle be angled 10–15 degrees caudally to avoid injury to the growth plate. The patient’s leg should be restrained and a small sandbag placed under the knee. The area should be cleaned and draped using sterile technique. Proper IO placement in the marrow canal can be confirmed by three methods. First, the needle should stand on its own without support. Second, after unscrewing the inner trocar from the needle, bone marrow should be able to be aspirated through the needle. Third, a 5–10-mL saline bolus injection should enter with little resistance and without evidence of extravasation; this can be confirmed by carefully observing the calf area for acute swelling or discoloration. Only one IO attempt should be made in each bone. Multiple punctures in the periosteum may result in extravasation of fluid into the soft tissues. However, if the needle becomes plugged with soft tissue, it may be removed, and a new needle may be inserted through the same cannulation site.[11]
It is recommended that IO needles should not be placed at fractured extremities because extravasation will occur at fracture sites. The tibia and distal femur are recommended sites in infants and children younger than 6 years. These sites are easily identified by topical landmarks, and the bones are superficially located. Needles inserted in these locations traverse tissue planes devoid of important structures, and the marrow cavity is relatively large. These sites are also physically removed from other resuscitative efforts, such as airway management and chest compressions. Also it is worth noting that secure vascular access should be obtained before the functioning IO needle is removed.
As this case report demonstrates, compartment syndrome can become a complication of IO insertion and this has been previously reported [14,15,17]. We speculate that this resulted primarily from extravasation of fluid into the muscular compartments. The potential causes for this extravasation include incomplete penetration of the cortex, penetration of the needle through the posterior aspect of the cortex, extravasation through a previous IO puncture site, and extravasation through the foramina of the nutrient vessel [17]
Precautionary measures that reduce the incidence of compartment syndrome and allow for its early recognition include correct placement of the IO line to reduce the amount of fluid extravasation. A fresh, large-bore needle should be used to facilitate bone penetration, prevent blockage of the lumen, and withstand bending forces. Multiple breaches of the cortex should be avoided, and the needle should be passed only through the near cortex. Aspiration of marrow contents confirms accurate placement, and free flow of fluid into the osseous cavity should be noted. Plain radiographs can also be used to confirm placement. If improper placement is confirmed, and the cortex has been breached, the site should be well dressed, and insertion can be attempted at another site. It is important that the affected limb be immobilized during use of the IO line to prevent dislodgement of a properly placed needle. The cannula should be secured to the extremity with a noncircumferential dressing to prevent. If possible, the circumference of the extremity at the level of the IO site should be measured serially. Although not immediately life-threatening, IO-line complications can be associated with extensive morbidity. If there is any concern that compartment syndrome is developing, the IO line should be removed immediately, and the appropriate surgical or orthopaedic service should be consulted.
We believe that if compartment syndrome is being considered because of the clinical examination and/or elevated intracompartmental pressures in patients post IOI, it may be worth employing this technique before proceeding to surgical decompression. If successful, as in this case, can lower intracompartmental pressures quite significantly and quickly. Whilst we do not anticipate any major complications unique to this technique, if it is unsuccessful and surgical decompression is delayed the patient may develop the complications of late compartment syndrome. As such, we would advise very close clinical monitoring post-bandage application and low threshold for surgical decompression if the compartment pressures do not lower quickly. If the compartment syndrome is not due to extravasation post IO insertion, we would not expect this technique to work and surgical decompression would most likely be needed.. As such, we are not suggesting this novel technique is a panacea for compartment syndrome but should only be considered in a patient who has developed compartment syndrome post IO insertion and does not have another likely cause for compartment syndrome.
Unfortunately, given the emergent nature of our case, we are unable to provide photographic evidence of our novel treatment as patient care and treatment was the priority at the time and the idea of case report was formulated afterwards. We would like to confirm however that we stand over the authenticity of the case.
We would like to report this technique with the eschmark bandage for lowering intracompartmental pressures in cases of extravasation of fluid into the soft tissue in the case of IOI before proceeding with surgical decompression. This technique is far less invasive than surgical decompression and if the pressure can be lowered significantly, as in this case, the need for proceeding to surgical decompression can be negated.

Abstract

Several osteotomies are available to correct cubitus varus and valgus deformities in children. The purpose of this study was to evaluate clinical and radiological outcome following Kim’s step cut translation osteotomy for such deformities.
Materials and Methods: We have instituted Kim’s step cut translational osteotomy in seven children having deformities of elbow (cubitus varus – 4 and cubitus valgus – 3). Patients were followed up for a period of 8 to 14 months during the period of August 2014 to October 2015. Clinically and radiologically, preoperative and postoperative Humerus-Elbow-Wrist angle, Range of motion of elbow, Lateral/Medial Prominence Index and neurological examination for ulnar nerve were determined. Results were evaluated according to modified Oppenheim et al criteria.
Results: The mean postoperative Humerus-Elbow-Wrist angle in patients with cubitus varus was 8.5±2.06 0 (range, 50 to 100). The mean improvement in Lateral Prominence Index was 7.4 ±1.28% (from –13.15% to -5.75% ). In cubitus valgus patients, mean
postoperative Humerus-Elbow-Wrist angle was 12.33±3.510(range, 80 to 150) . The mean improvement in MPI was 8.7±0.83% (from -15.5% to -6.8% ) . In all patients range of motion was comparable with normal side elbow. Bone union was achieved in all patients. According to Oppenheim’s criteria, six patients had excellent results and one patient had good result. .None of them had any complications.
Conclusion: Even though multiple procedures are available for correcting deformities of elbow, Kim’s step cut translational osteotomy provides good correction angle, lesser prominence of the condyle, better stability and three dimensional correction.
Key Words: Cubitus varus, Cubitus valgus, Kim’s osteotomy, Lateral/ Medial prominence Index.


Introduction
Cubitus varus and valgus deformities are complications of elbow fractures in children[1]. Cubitus varus has multiple components that include varus malalignment, hyperextension and internal malrotation[2,3]. The most important indication for osteotomy is to achieve a good cosmesis[2,4]. Many surgical techniques have been described to correct these deformities including closing wedge, opening wedge, dome and step cut osteotomies[5-12]. The closing wedge osteotomy has a tendency to produce prominent condyles after correction,often compromising the cosmetic outcome[2,13-16]. The inclusion of translation in the osteotomy improves cosmetic appearance by minimizing the persistent prominence of the medial or lateral condyle. This can be achieved by Kim’s osteotomy. The aim of our study was to evaluate clinically and radiologically, the preoperative and postoperative Humerus-Elbow-Wrist(HEW) angle, Lateral/Medial Prominence Index(LPI/MPI), Range of Motion(ROM), in children undergoing Kim’s step cut translation osteotomy for cubitus varus and valgus.

Materials and Methods
This is a retrospective study, from August 2014 to October 2015, involving seven paediatric patients in the age group 8 – 14 years with male:female ratio of 4:3. Those with cubitus varus deformity had sustained supracondylar humerus fracture and those with valgus deformity had fracture lateral condyle. All the patients had undergone native treatment immediately after injury, and presented to our department after a period of 14 months to 34 months after injury.
We have instituted step cut translational osteotomy of Hui Taek Kim [1] in all the seven patients. Preoperatively, radiological and clinical planning includes measurement of HEW angle, lateral/medial prominence index (using the method described by Wong et al [2,16]),range of motion of elbow, neurological examination for ulnar nerve and internal rotation malalignment (using the method described by Yamamoto[17,18]). Same radiological and clinical parameters were evaluated postoperatively.
HEW angle was measured by drawing two lines, one line along the anatomical axis of humerus ,and another line joining midpoints of two transverse lines(one proximal and one distal) across the forearm that connected the medial cortex of ulna and lateral cortex of radius (Fig-1). The Lateral/Medial Prominence Index was measured by using the formula shown in (Fig-2).
We determined the Correction Angle (CA) for patients with cubitus varus by adding varus HEW angle with normal side HEW angle, and for patients with cubitus valgus by subtracting normal side HEW angle from affected side valgus HEW angle. A template using X-ray film, was prepared preoperatively, to mark the site and size of osteotomy, using following technique(Fig-3).
The outline of the bone was drawn on a trace paper. A horizontal line was drawn perpendicular to anatomical axis of humerus at a level 0.5 to 1 cm proximal to the olecranon fossa. Now the trace paper was cut along the horizontal line and the distal fragment was rotated laterally and translated medially(in case of cubitus varus) so as to achieve HEW angle of normal side. Vice versa was done for cubitus valgus deformity. An inverted V was marked on the trace paper. We then cut out the triangular overlapping area from the paper and prepared X-ray film of same size and shape. This triangular X-ray film was sterilised for
use during osteotomy.

Method of Osteotomy
With the patient in lateral decubitus position,through posterior approach ,ulnar nerve was isolated and protected. The triceps aponeurosis was split. The triangular X-ray template (turned face downward because of posterior approach) was placed over the bone 1cm proximal to olecranon fossa and necessary osteotomy was done to remove an identical piece of bone. The distal fragment was rotated laterally for cubitus varus(and medially for cubitus valgus) and inserted into the inverted V shaped defect. The deformity correction was assessed clinically and then the fixation was done with distal radius T-Plate and 3.5mm cortical
screws. The ulnar nerve was transposed anteriorly in patients who had tardy ulnar nerve palsy due to cubitus valgus deformity.
Patient was immobilised in long arm slab for 2 weeks following which active and assisted mobilisation was done intermittently retaining the splint until radiological union was achieved.

Results
The HEW angle, LPI/MPI, ROM were measured and analysed (Table -1).

In cubitus varus patients, mean postoperative HEW angle was 8.50(range, 50to 100),with mean correction of 21.50(range,190 to 250). The mean improvement in LPI was 7.4% (from -13.15% to -5.75% ) .In cubitus valgus patients(Fig-5), mean postoperative HEW angle was 12.330(range, 80 to 150),with mean correction of 21.660(range,200 to 230). The mean improvement in MPI was 8.7% (from -15.5% to -6.8% ).In all patients, range of motion was comparable with normal side elbow (Table 1). Pronation and supination movements were normal in all our cases. Bone union was achieved in all patients.

Discussion
In patients with cubitus varus/valgus, the following problems need to be addressed deformity correction in coronal plane(valgus/varus), sagittal plane(fixed flexion/hyperextension),horizontal plane(internal/external rotation deformity); ulnar nerve palsy, if any.
The deformity is better corrected during childhood. Correction, particularly in cubitus varus, in adult is challenging due to mature skeleton, inherent instability at osteotomy site, risk of delayed union/non union, implant failure, infection, stiffness and neurovascular complications [19]. A rough estimate will be around a year after original injury. Again patient demands, growth potential and status of physis should be taken into account while planning surgery[20].
Major types of osteotomies are – simple closing wedge [17,21,22],step cut translation [1,17,23], dome rotational osteotomy[13,14,17,24] and spike translation osteotomy[17]. Many of these osteotomies have got their own disadvantages, like lateral scar, medial and lateral condylar prominence and difficulty in correcting rotational deformities( due to contractures)[1,24,25,26].
Various method of fixation include use of K-wires, screws, plates and external fixators (Ilizarov technique) [5,13,25,27-29]. We have used Kim’s method of step cut translation Osteotomy, and fixed with distal radius T-plate.
This method has got multiple advantages. Adequate Correction Angle (CA) is achieved by moving the apex more medially (in cubitus varus) or laterally (in cubitus valgus). The stability of fixation is enhanced because the distal fragment is inserted into the inverted V shaped proximal fragment and fixation was done with plates. The prominence of condyles (lateral condyle in cubitus varus and medial condyle in cubitus valgus) is less with Kim’s osteotomy (when compared to other methods ) because distal fragment is translated. With Kim’s osteotomy, three dimensional correction is possible. The correction of internal rotation is recommended when the difference in rotational alignment in both sides is greater than 100 [1,17,18]. In our study ,we did not encounter patient with hyperextension, or internal rotation more than 100, when compared to normal side. Hence we have not attempted correction in sagittal/horizontal planes.
The limitations of our study is smaller sample size and follow up of only 14 months duration.

Conclusion
This simple step cut translation osteotomy(Kim’s) results in good cosmetic deformity correction,very firm fixation,earlier elbow movement and also avoids problems of condylar prominence and non union. Deformities in sagittal/horizontal plane can also be corrected.

Abstract

Thumb hypoplasia/aplasia is one of the components of radial longitudinal deficiency. It can occur either alone or it may be associated with other components of radial longitudinal deficiency. Aim of thumb reconstruction is to provide a functional and stable thumb which will improve the grip and aesthetic appearance of hand. Pollicisation is the treatment for Type IIIB,IIIC, IV and V types of thumb hypoplasia as per Blauth’s Classification as Modified by Manske and Buck-Gramcko. In the opinion of the authors, pollicisation is one of the finest and most difficult operations in reconstructive hand surgery.
Keywords: Pollicisation: History, Principles and Surgical technique.


Introduction
Napier has said “The hand without a thumb is at worst, nothing but an animated fish-slice, and at best a pair of forceps whose points don’t meet properly”. [1]
Thumb hypoplasia is a congenital condition, which can range from slightly small digit to deficiency of some musculotendinous units or osseous components to complete absence of thumb.40% of the hand function relies on a strong thumb. [2]For proper functioning of the hand, thumb size, its position,mobility and the relation with other fingers is critical. Children with thumb hypoplasia can manipulate small objects using side to side pinch, between adjacent digits, ‘Chopstick’ action; but it is difficult to grasp large objects. [3]
Thumb hypoplasia/aplasia is one of the components of radial longitudinal deficiency. It can occur either alone or it may be associated with other components of radial longitudinal deficiency. A wide range of manifestations on the preaxial side of the upper limb is seen in radial longitudinal deficiency. Hence, in any case of thumb hypoplasia, one should examine proximal forearm and contralateral thumb.
Incidence
Thumb hypoplasia is a component of various congenital malformations like thumb duplication, transverse deficiencies, brachydactyly, symbrachydactyly, cleft hand complex, constriction ring syndrome etc., and hence it is very difficult to find out the true incidence of thumb hypoplasia alone. Tay SC et al in 2006, reported upto 16% incidence of thumb hypoplasia amongst congenital hand deformities. [4] There is equal distribution of cases between male and female. About 60% cases have bilateral involvement with often asymmetrical involvement. [5] In unilateral cases, right hand is more commonly affected. [6]
In a study by Abdel-Ghani and Amro, [7] 86% cases of thumb hypoplasia were associated with various conditions involving cardiovascular, gastrointestinal and genitourinary system. Various conditions commonly seen in association with thumb hypoplasia are Holt-Oram syndrome, VACTERL association, Fanconi’s anaemia, Thrombocytopenia absent radius(TAR) syndrome. [6] The severity of radial longitudinal deficiency is directly proportional to the degree of thumb hypoplasia according to James et al. [8]

Genetics
The upper limb bud appears at 4th week of embryonic development opposite the caudal cervical somites. Various signalling centres have been identified that are responsible for upper limb development. [4,8]
1. Apical Epidermal Ridge(AER) – responsible for proximal to distal development (shoulder to hand) and is mediated by number of fibroblast growth factors.
2. Zone of Polarizing Activity (ZPA) – responsible for anterior-posterior pattern formation(also called Pre and Post Axial) and is mediated by sonic hedgehog (Shh) and homeobox (HOX) gene products.
3. WNT7a signalling centre – responsible for dorsal ventral development.
The exact mechanism of embryologic insult that leads to thumb hypoplasia is unclear. Abnormalities in AER or ZPA can lead to thumb hypoplasia. Studies have proved that administration of teratogenic agents or inactivating fibroblastic growth factors in rats and mice can lead to radial longitudinal hypoplasia with thumb hypoplasia. [10]
The deletion of chromosome 22q11 can lead to thumb hypoplasia in radial longitudinal deficiency [5]. However, it is difficult to point out single gene or enzymatic defect as the cause for thumb hypoplasia [8].

Classification
Thumb hypoplasia can present with wide range of functional and aesthetic differences. Hence careful inspection and examination is required. One should carefully examine the size, position, skeletal components, intrinsic and extrinsic muscles, joint stability, and first web space and associated conditions. One should correlate soft tissue and skeletal deficiencies while taking decision about the treatment.
Classification helps in taking decision about the treatment. In 1937, Muller first classified thumb hypoplasia. It is currently the Blauth’s classification which is widely accepted in classifying and as a guide for surgical planning. Manske further classified type 3 hypoplasia in A and B depending on stability of CMC joint. [4, 11]

Blauth’s Classification as Modified by Manske and Buck-Gramcko:

Type I: Mild hypoplasia
Slight decrease in thumb size
Slender phalanges and metacarpals
Normal intrinsic muscles
Normal trapezium, scaphoid, distal radius and styloid process

Type II: Moderate hypoplasia
Underdeveloped or absent thenar muscles
Adducted posture- first web space narrowing
Ulnar Collateral ligament (UCL) insufficiency at MP joint
CMC stable

Type III: Severe hypoplasia
All the features of type II plus
Radial carpal aplasia
Extrinsic muscle and tendon abnormalities
Type III A: Stable CMC joint
Type III B: Unstable CMC joint
Type IIIC: Buck Gramcko has added this variation in which thumb has only metacarpal with no musculotendinous unit and a wider skin bridge
Type IV: Pouce floutant (French Floating thumb)
Thumb is small and has rudimentary skeletal elements. It is an unstable digit, connected to the hand by only a skin bridge containing the neurovascular bundle.
Type V: Aplasia i.e.Absence of all thumb structures and radial carpal bones

Evaluation
Thumb hypoplasia can be the only presentation of radial longitudinal deficiency or it may be associated with other anomalies. Plain bilateral radiographs will help to assess thumb phalanges, metacarpal and carpometacarpal joint. One should assess wrist and forearm to rule out radial longitudinal deficiency.
As thumb hypoplasia can be associated with other syndromes, thorough cardiac, renal, haematological and musculoskeletal evaluation is essential. Common investigations include a complete blood count, 2D Echo Cardiogram and sonography abdomen for solid organs. This is important as the treatment of these conditions may take priority over thumb hypoplasia management. [12]Any positive findings may also impact anaesthesia for surgery.

Treatment
Aim of thumb reconstruction is to provide a functional and stable thumb which will improve the grip and aesthetic appearance of hand.
Typically Type I is more or less a functional thumb,hence no treatment is required.
Type II: depending on findings; first web space release, opponensplasty using Abductor Digiti Minimi (ADM) or other suitable donors and/or UCL reconstruction
Type III A: same procedures like type II and in addition may require further additional extrinsic tendon transfers to improve the function, which transfers and how needs to be decided on a case by case basis, depending on need.
Type IIIB,IIIC, IV and V: Pollicisation

Timing of surgery:
Surgery at an early age is recommended for better functional results as it will allow cognitive development and physiological adaptation of the reconstructed thumb before corticalisation which happens around 18 months of age. [13]
We are basically going to discuss about pollicisation in advanced hypoplasia IIIB onwards or Aplasia in this paper.
Pollicisation is a Latin word; Pollex means thumb and Pollicisation is defined as reconstruction of thumb using the adjacent radial finger.

History of pollicisation
In 1885,Guermonprez seems to be the first person to report a case of pollicisation. Before the second world war, many surgeons Dunlop (1923), Bunnell (1931) have reported doing pollicisation. However, follow up study of these cases had unsatisfactory results.
The major modification in the procedure was seen after the Second World War. Gosset (1949) [14] described index finger and ring finger pollicisation on neurovascular pedicle without skin attachments. Middle finger pollicisation was described by Hilgenfeldt (1950) [15]. Further contributions were by Bunnell (1952), Littler (1953). [16.17]
In 1971, Buck Gramcko published an article about pollicisation [18] which is the landmark article in establishing the technique of pollicisation in our opinion. Buck Gramcko’s major work on pollicisation evolved after the thalidomide tragedy in Europe which had led to many congenital hand and upper limb anomalies. Manske, Foucher et all have modified the technique but Buck Gramcko’s technique is the gold standard method still commonly used. The authors use the Buck Gramcko technique.

Principles of Pollicisation:
In 1990 Littler had said:
“It is not the full length of the thumb, nor its great strength and movement, but rather its strategic position relative to the fingers and the integrity of the specialized terminal pulp tissue which determines the prehensile status.”

Littler has classified requirements of the procedure as follows [19]
Mechanical
1. Correct length
2. Strategic position
3. Stability

Physiological
1. Movement
2. Sensibility
3. Absence of pain
4. Integration

Satisfactory appearance
In the opinion of the authors, pollicisation is one of the finest and most difficult operations in reconstructive hand surgery. Patient’s parents have a tough time deciding about amputing the useless thumb and using index finger for thumb reconstruction. Authors feel it is simultaneously rewarding to and taxing on the surgeon performing it. [20]

TECHNIQUE Figs. 1- 17
Fig. 1,2 and 3 represent pre operative photos and X-Ray.
Markings as per Buck-Gramcko (Fig. 4,5) Senior author (MRT) starts the surgery by raising the dorsal flaps taking care to preserve dorsal venous network. (Fig. 6)
Once the dorsal flaps are raised preserving dorsal venous network, palmar incisions are made and pedicles are dissected on the palmar side. Sometimes it may be required to open the neural ring on the ulnar side pedicle,if it is present.(Fig.7)

Figure 7: Dissection of vascular pedicles of Index finger

Figure 7: Dissection of vascular pedicles of Index finger

After dissecting and safeguarding the pedicle, first dorsal interosseous and first palmar interosseous with lateral band extension is identified and cut. To identify the distal lateral band at the time of final suturing, a 6-0 nylon suture is used for tagging the remaining lateral band (Fig. 8,9,10)

Figure 10: First palmar interroseous raised with tendon

Figure 10: First palmar interroseous raised with tendon

Next step is to identify the two extensors – extensor indicis proprius and extensor digitorum communis of index finger and cut them. In more severe variants of Radial dysplasia only one tendon is present.(Fig. 11)

Figure 12: Extensor Indicis proprious (EIP) cut and raised off MP joint so as to act on distal interphalangeal as future extensor pollicis longus

For setting the index completely free, the deep transverse metacarpal ligament between index and middle finger has to be divided. (Fig. 13)

Figure 13: Dividing deep transverse metacarpal ligament between index and middle finger

Figure 13: Dividing deep transverse metacarpal ligament between index and middle finger

The line of division of metacarpal is through the epiphysis at the level of the head. The shaft is disarticulated at the CMC joint and is excised extra-periosteally.(Fig. 14,15)

Figure 14: Division of index finger metacarpal at the level of head of metacarpal

Figure 15: Metacarpal shaft disarticulated at carpometacarpal joint

Figure 15: Metacarpal shaft disarticulated at carpometacarpal joint

At every step, one has to be careful about the neurovascular pedicle of the index finger.
The metacarpal head has to be rotated by 900 in extension and fixed with 4-0 nylon to prevent hyperextension of the new CMC joint.(Fig 16)

Figure 16: Rotating metacarpal head dorsally by 900

Figure 16: Rotating metacarpal head dorsally by 900

Index finger is now rotated 150 degrees, abducted 40-50 degrees and fixed at the CMC level with a 4-0 nylon suture which goes thru the CMC joint- head of metacarpal-CMC other lip.(Fig 17)

Figure 17: Index finger is fixed at CMC level

Figure 17: Index finger is fixed at CMC level

The Extensor/s are sutured first. The EIP becomes the EPL and the EDC becomes the APL
The Metacarpal level attachment of the EIP is dissected off; this enables the EIP to act on the DIP as an extensor. (Fig 12)
The EDC is kept attached at the base of the PPx of the IF so that once the tendon is reattached it acts as the APL.
The First dorsal interosseous is attached next to the lateral band to become the new abductor – opponens complex.(Fig. 18)

Figure 18: Suturing first dorsal interosseous to lateral band as the new abductor opponens complex

Figure 18: Suturing first dorsal interosseous to lateral band as the new abductor opponens complex

Dorsal flaps are sown.
The Palmar Interosseous is now attached to the other lateral band to become the Adductor Pollicis.
Skin flaps are now adjusted and closed to get the new thumb(Pollex) in opposition and pronation to achieve pulp to pulp pinch.(Fig. 19)

A bulky padded dressing is given to protect the new thumb and tourniquet released and vascularity of both arteries and veins is checked.(Fig. 22)
Fig. 19 shows a long term result

Complications of procedure
Losing the finger—very rare but possible
Skin necrosis
Hyperextension at CMC joint
Too long length
Functional Result may not be as good in severe radial longitudinal deficiency. There are chances of abnormalities of muscles of index finger and stiffness of index finger PIP joint in these cases (Symphalangism) which leads to relative functional impairment following pollicisation.
In our opinion it is still better than a four fingered hand at all times

Conclusion
Pollicisation is the optimum method of thumb reconstruction in thumb hypoplasia/aplasia

Abstract

Radial longitudinal dysplasia continues to challenge the pediatric hand and upper limb surgeon. Despite decades of clinical experience and research, surgical strategies to improve wrist alignment and upper limb function remain imperfect, with persistent concerns regarding recurrent deformity, stiffness, and distal ulnar growth disturbance. For these reasons, many authors have proposed alternative treatment paradigms to traditional centralization techniques. The purpose of this review is to explore the arguments for surgical treatment, to identify the potential sequelae of traditional centralization, and to present an “alternative treatment paradigm” for radial longitudinal dysplasia.

Key Words: Radial longitidinal dysplasia, centralization, bilobe flap


Introduction
Radial longitudinal dysplasia (RLD) refers to failure of formation of the radial aspects of the hand and forearm, and is currently classified as an abnormality of formation and differentiation of the antero-posterior axis of the developing upper limb by the Oberg-Manske-Tonkin classification system [1].The incidence is thought to be between 1 in 30,000 and 100,000 live births , and RLD has a slight male and right-sided predisposition. Over half of patients have bilateral upper limb involvement.
There is a broad spectrum of anatomic anomalies involving the skeletal, muscular, and neurovascular structures, and associated syndromes are common, including VACTERL association, Holt-Oram syndrome, Cornelia de Lange syndrome, thrombocytopenia-absent radius, Diamond-Blackfan anemia, Rothmund-Thomson syndrome, and Fanconi’s anemia [2,3,4,5]. A host of condition-specific schemes have been proposed, based mostly upon the severity of bony involvement, and to date the modified Bayne and Klug classification continues to be used by most providers [6,7].
Overall, the goals of treatment include maximizing upper limb and hand function, ideally by preserving wrist motion, improving wrist alignment, maintaining limb length and growth potential, and preserving the ability for subsequent hand reconstruction and pollicization. Furthermore, the aesthetic differences –and secondary effects thereof– imparted by RLD must be recognized and considered in an appropriate fashion.
A host of questions continue to be raised with the growing experience of RLD treatment, particularly with longer term follow-up and patient-derived functional outcome measures. What is the natural history of RLD? Is surgical treatment for deformity correction worthwhile? And if so, what is the best method of treatment to maximize function and minimize complications?
The purpose of this review will be to address these questions using the available information from India and the United States, and in doing so, present an alternative treatment algorithm for patients with RLD.

Natural History versus Surgical Reconstruction
With any congenital difference, the first fundamental task of the pediatric orthopaedic surgeon is to understand the natural history of the condition and the comparative outcomes of natural history versus surgical treatment. Kotwal et al. published an important paper seeking to address this fundamental question as it relates to RLD [8]. One hundred and three patients with RLD treated non-operatively were compared to 239 patients treated with surgical reconstruction. All patients had Bayne type 3 or 4 deficiency and were treated at a single center from 1985 to 2004. Patients were assessed according to standard clinical parameters, radiographic measurement of the hand-forearm angle (HFA), and visual analogue scores (VAS) for pain and aesthetic appearance. Grip strength was evaluated using dynamometry, though pinch strength was not measured due to the heterogeneity of hand/thumb involvement. The Prosthetic Upper Extremity Functional Index (PUFI), originally developed to evaluate function in patients with transverse upper limb deficiencies, was used to assess upper limb function.
Non-operative treatment consisted of early stretching, serial casting, splinting, and.or functional bracing. Centralization consisted of centralization (n=202) or radialization (n=107) via an ulnar incision, excising redundant ulnar skin, notching the carpus, reefing the wrist joint capsule, preserving the distal ulnar physis, and stabilizing with a 1.6mm Kirschner (K-) wire [9,10]. Tendon transfers were performed in selected cases. Radialization was performed in a similar fashion, though tendon transfers were more commonly performed and K-wire fixation was achieved through the index metacarpal [11].
Overall, patients with type 3 and 4 RLD treated with surgical reconstruction demonstrated better PUFI scores, had improved HFA, and reported improved aesthetics than non-operatively treated patients. However, surgical patients also had decreased wrist range of motion (ROM), and interestingly functional results as assessed by the PUFI correlated best with digital ROM, regardless of treatment type. Ekblom et al. similarly reported that digital and wrist ROM is more important for activity and participation than HFA in their analysis of 20 patients with RLD [12]. Holtslag et al. similarly found that only ROM of the didgits correlated with function, as assessed by the Sequential Occupational Dexterity Assessment [13]. No significant differences in activity and participation between patients with mild versus severe RLD. Thus, while there is published information suggesting that surgical treatment provides functional, alignment, and aesthetic improvements that are superior to natural history, it is important to remember the importance of wrist and digital ROM in upper extremity and hand function.

Concerns with centralization
Surgical treatment in the form of centralization or radialization is not without concerns. First the longevity of correction and functional improvement continues to be debated. In their longer-term follow-up study of 25 wrists treated with centralization, Goldfarb et al. reported recurrent deformity (HFA of 25 degrees), limited wrist ROM (mean arc 31 degrees) and forearm shortening (ulnar length 54%), perhaps due to iatrogenic distal ulnar physeal disturbance [14].
In efforts to minimize the soft-tissue tension and thus the risks of recurrent deformity, stiffness, and growth arrest, many authors have advocated pre-centralization distraction using a host of external fixation constructs. In theory, pre-centralization distraction reduces soft tissue tension, facilitates centralization, obviates the need for carpal notching or prolonged implant placement which may contribute to distal physeal disturbance. Thatte and Mehta reported on a series of 29 wrists treated with distraction and subsequent radialization at a young age [15]. HFA improved from 74 to 10 degrees, ulnar length was maintained at over 70%, and correction was maintained at mean 6.5 year follow-up. These results are excellent by all accounts, but have not been consistently reproduced in all centers.
Manske et al. compared 13 wrists treated with centralization alone to 13 wrists treated with centralization preceeded by distraction [16]. With centralization alone, HFA improved from 53 degrees pre-operatively to 13 degrees immediately post-operatively to 27 degrees at most recent follow-up. With pre-operative distraction, HFA improved from 53 degrees pre-operatively to 21 degrees immediately post-operatively to 36 degrees at last follow-up. Based upon the similar amount of recurrence, the authors concluded that distraction may facilitate surgical centralization but does not necessarily minimize recurrence. Similar findings were noted by Dana et al. in a series of 8 patients with over two-year follow-up, as well as Lamb et al, McCarthy et al., Shariatzadeh et al, and others [17,18,19,20].
The second concern with centralization techniques has been the risk of iatrogenic ulnar growth disturbance, resulting in upper limb length discrepancy and shortening of an already dysplastic forearm. Potential factors contributing to the risk of ulnar physeal arrest include devascularization from soft tissue dissection around the distal ulna, carpal notching and increased pressure imparted on the distal ulna during centralization, as well as the placement and retention of an intramedullary implant crossing the ulnar physis. Sestero et al. evaluated ulnar growth patterns in 124 limbs of 90 patients and found decreasing ulnar growth in patients treated with non-notching and notching centralization techniques [21]. Indeed, non-operatively treated limbs retained 64% of “normal” length, whereas those patients who underwent non-notching and notching techniques of centralization had ulnar lengths of 58% and 48%, respectively.
To counteract and address both recurrent radial deviation deformity as well as ulnar shortening, several authors have proposed late reconstruction consistent of ulnar lengthening with or without subsequent ulnocarpal arthrodesis. Farr et al. reported on 8 forearm lengthenings performed in 6 patients at mean age of 10 years [22]. At almost 5 year followup, a mean of 7cm of lengthening was achieved. HFA improved from 25 degrees pre-operatively to 11 degrees post-operatively, though recurrent deformity was again observed, with a final follow-up HFA of 23 degrees.
Arthrodesis –or chondrodesis in the skeletally immature—allows for correction of wrist deformity at the expense of ulnocarpal motion. Pike et al. reported on 12 patients with recurrent radial deviation of greater than 45 degrees who underwent ulnocarpal chondrodesis with Kirschner (K-) wire fixation [23]. Patients had a mean post-oeprative DASH score of 24.5, with visual analog scores (VAS) of 7 and 8 for appearance and function, respectively.
Based on these and many other reports, the “classic” or traditional treatment algorithm in the United States and around the world has been (Fig. 1) early splinting, stretching and/or casting, followed by centralization with or without pre-operatively distraction. For those with recurrent deformity and/or excessive limb length discrepancy, ulnar lengthening and ulnocarpal chondrodesis or arthrodesis may be considered.

Is there another way?
While commonly utilized, the drawbacks of recurrent deformity, additional limb length discrepancy, and loss of wrist motion despite multiple surgeries have motivated many providers to consider alternative treatment options. Ideally, surgical treatment should preserve wrist motion and forearm length, and in doing so maximize hand and upper limb function. To this end, several authors from the United States and around the world have proposed an alternative treatment algorithm consisting of two stages (Fig. 2).

The first surgical step in this algorithm is addressing radial deviation of the wrist through soft tissue releases, capsulorraphy, and tendon transfers via bilobe flap reconstruction [24,25]. Philosophically, this represents a departure from traditional tenets of RLD surgery; the focus of releases is to improve wrist alignment while judiciously preserving the distal ulnar physis. Wrist motion is prioritized over alignment, given the evidence that function is most directly correlated to wrist and digital motion and that typical surgical interventions result in recurrence.
Technically, a bilobed flap may be performed either dorsally or volarly, depending upon surgeon preference and awareness of the aesthetic implications of dorsal scars and/or color mismatch between the dorsal and volar skin (Fig. 3). A proximally based flap is designed longitudinally which will be rotated or transposed to provide skin and soft tissue to the tight, often deficient radial wrist. A second lobe is based proximally and incorporating the excessive ulnar soft tissues, which will be rotated to cover the dorsal donor area. Careful flap elevation is performed to maintain vascularity to these random patterned flaps, with care to preserve subcutaneous nerve and vein, when possible. After the flaps have been elevated and mobilized, near circumferential exposure of the deeper structures is possible. Tight radial-sided structures are release, the ulnar capsule may be incised and imbricated, and tendon transfers (particular flexors to ulnar extensors) may be performed to achieve dynamic rebalancing across the wrist. Great care is made to preserve all the soft tissues around the distal ulna in efforts to preserve its vascularity and integrity of the distal ulnar physis. Temporary K-wire stabilization may be performed from the ulnar metaphysis to the carpus, avoiding wire passage across the distal ulnar physis. Splinting, therapy, and ROM exercises are begun at 4-6 weeks post-operatively.

Vuillermin et al. published their series of 18 wrists in 16 patients treated with soft tissue release and bilobe flap reconstruction [24]. A t mean 9 year follow-up, HFA improved modestly from 88 degrees pre-operatively to 64 degrees at most recent follow-up. However, patients maintained a mean of 73 degree wrist flexion-extension and had Disabilities of the Arm, Shoulder, and Hand (DASH) scores and global Pediatric Outcomes Data Collection Instrument (PODCI) scores of 27 and 88, respectively. VAS scores for overall satisfaction were quite high (mean 1.2 on a 10 point scale). These patient-derived measures of outcome compare favorably to other published information regarding the results of centralization. Importantly, there were no physeal growth disturbances, and no patients went on to secondary ulnocarpal chondrodeses or other salvage procedures.
After soft-tissue releases via bilobe flap reconstruction, subsequent soft-tissue distraction and free vascularized metatarsophalangeal (MTP) joint transfer may be performed in a secondary staged fashion [26,27]. Pioneered by Dr. Vilkki, free MTP joint transfer provide an attractive, albeit technically demanding, option to provide more durable carpal support and maintain more normal HFA.
As originally described, distraction lengthening is performed across the ulnar aspect of the wrist, with half pin or smooth wire fixation into both the proximal ulna and ulnar metacarpals [27]. Once adequate distraction has been achieved and more normal wrist alignment restored, free second MTP joint transfer is performed. Arterial inflow is typically achieved from the radial artery to the plantar metatarsal artery. Local veins are used for venous outflow. More extensive radial soft tissues are released, with the native FCR split and reattached to the donor toe flexor and extensor apparatus. K-wire fixation is typically utilized to fix the proximal ulna to the donor metatarsal as well as the radial metacarpals to the donor proximal phalanx; the previously applied fixator is retained for additional support during the early postoperative period. The transferred joint forms a Y-shaped “strut” to support the radial wrist and hand, thereby maintaining HFA while still allowing for wrist motion.
Vilkki previously reported on 19 wrists in 18 patients treated with distraction and MTP joint transfer. At mean 11 year follow-up, HFA was 28 degrees and wrist flexion-extension arc averaged 83 degrees [27,28]. While there was increased radial deviation over time, this change averaged 12 degrees over 10 to 15 years follow-up. Ulnar length is typically preserved, with length approximating two-thirds of normal.
While the author has no personal experience with free vascularized joint transfer, it should be noted that this procedure is generally delayed until later in childhood, given the technical challenges of the procedure. Interestingly, multiple authors have reported that patients often decline secondary MTP joint transfers, given their satisfaction and function following soft-tissue releases via bilobed flap reconstructions [25].
While early reports highlight the theoretical advantages in preserving motion and growth, the merits of this “alternative algorithm” bear further investigation. At present, there is little published information to compare the relative efficacy, durability, and long-term patient-reported functional outcomes of traditional centralization versus soft-tissue releases with or without free MTP joint transfer. In the United States, a multicenter prospective longitudinal cohort study is underway to address this, and other, important congenital questions [29].

Abstract

Radial hemimelia treatment has evolved a lot with many different types of surgical options; manifestations are myriad and presentations ages may vary from infancy to late childhood in most countries. A stepwise approach is needed for decision making and to manage this complex anomaly. The reader is presented here with a detailed clinical examination, decision making algorithm and an overview of surgical treatment options and the method preferred by the author with trends of interim and long term results and some other details in this review article.
Keywords: radial hemimelia, management, radial club hand


Introduction
Treatment for radial hemimelia has to be planned with a holistic picture in mind. The aim is to realign the carpus over the ulna in order to substitute for the missing radial pillar, as well as retain a good function, albeit without recurrence in an ideal world. The secondary issues of thumb aplasia and digital anomalies which invariably accompany the forearm deformity, need to be addressed separately: each on their own merit and severity. But since this anomaly involves multiple problems the whole balancing act is one of correct decision making and optimal clinical timing of each procedure.

Clinical examination
The first foundation for a proper decision making is a good clinical examination. The following typical features (as shown in Fig (1 and b) are often present and should be evaluated in detail

c) With or without elbow synostosis or varying degrees of stiffness,
d) Thumb hypoplasia to aplasia,
e) Anomalies of the digits like symphallangism or camptodactyly,
f) Oligo dactyly or oligo-syndactyly.
The shoulder, elbow, wrist, and digital range of movement should be noted; in an infant often difficult; for active and passive motion. The ability to flex the elbow for hand-to-mouth function is examined, as this influences the treatment algorithm. Any procedure on the wrist is contra-indicated in the presence of an elbow synostosis. The position of the wrist with respect to the ulna and the ability to passively correct the radial deviation also are measured. The hand forearm angle (Fig 3a). as described by Manske and Goldfarb [1] should be carefully documented. The amount of ulnar bowing and angle of deviation from long axis should also be measured
The thumb is examined for hypoplasia and graded accordingly (elaborated in forthcoming part II of the symposium) Thumb deficiency contributes to functional impairment. Stiffness of the fingers is assessed, and the ability to grasp and release is determined via functional tasks. ‘Chop-stick ‘ grip between the index and middle finger or at times rarely even between ring and little finger is seen in late untreated children especially after 2 years of age . However the above features may vary with the degree of radial deficiency and the presence of associated anomalies. [2]. A thorough systemic evaluation is nevertheless mandated despite variations. The principal organ systems involved in these are the cardiac, renal, and hematological (though some of these may not manifest before 5 to 6 years of age), vertebral, occasionally foot and ankle, trachea-esophageal, and anal problems. Details of the various syndromes and their clinical relevance are explained in article by Chatterjee et al

Surgical Decision making
Type I radial club-hands have minor radial deviation of the wrist, which creates less of a functional problem than types II, III, and IV. (for details of classification refer to article by Sheth and Kumar) In these severe grades of dysplasia particularly with considerable absence of the radius, the wrist assumes severe radial deviation that increases to 90° over time. This further compromises the flexor and extensor tendons range and length, creating functional difficulty. The goals of treatment besides improving function of the extremity are [3,4] :
• To correct radial deviation
• Balance the wrist on the forearm
• Maintain mobility
• Promote growth of the forearm
• Enhance limb appearance for better body image
Centralization is indicated in radial club-hand types II, III, and IV, in which there is severe radial wrist deviation (than 30 degrees or more) [5] and insufficient support of the carpus. The carpal ring is pivoted back into position over the carpus by releasing all tethers on radial aspect, open reduction of ulno –carpal joint and capsulorrhaphy and restoring wrist stability, which is highly essential for development of a good power grip and other reconstructions. This is quite similar to what is done in developmental dysplasia of the hip. The optimum timing for performing centralization surgery is ideally 6 months of age before the onset of hand to mouth reflex. [8]. Correction of deformity early allows the brain cells to recognize normalized wrist alignment and mechanics as part of body image in the developing brain a phenomenon known as cortical adaption.
Thumb hypoplasia also requires consideration when formulating a treatment plan for radial club-hand. An absent or deficient thumb inhibits use of the hand in the correct prehensile way that was designed for human anatomy. Thumb reconstruction is usually delayed until after forearm treatment. Individuals not treated thus in the correct sequence of forearm and thumb correction may develop erroneous compensatory patterns like “chopsitick” action shown in (Fig 2b) which are very difficult to eliminate after early childhood as they get permanently established in the brain .

Contra-Indications
Contraindications for surgical intervention are a limited life expectancy in a child and elbow extension contractures that prevent the hand from reaching the mouth if the deformity at the wrist is corrected [6]. Surgery is also contraindicated for adults who have adjusted to their deformity (Fig 2a).

Investigations
As a protocol ALL radial dysplasia patients should be fully investigated and referred to pediatric subspecialists [2]. The heart is evaluated by auscultation and echocardiography. The kidneys are examined by ultrasound, and the platelet status is assessed by blood count and peripheral blood smear.
Plain radiographs are obtained to evaluate the degree of radial aplasia (Fig 3a) and to assess associated abnormalities of the elbow, wrist, and hand and spine when indicated . In radial club-hand, ossification is delayed,(fig 3b) and final determination of complete aplasia of the radius or carpus must be deferred until later almost up to the age of 8 years ( Fig 3c). In some cases a frank synostosis of the ulno- humeral joint may also be seen early. X rays of the whole spine AP and lateral should also be done as a screening to detect subtle VATER anomalies and vertebral involvement. In established cases it is better to evaluate the spinal involvement with more focused and detailed x rays and higher imaging whenever necessary.
For details of further investigations particularly the hematological ones which may have a bearing on the life expectancy of the child please refer to chapter no 2. The visceral anomalies get priority over centralization if life threatening , but with modern day anesthesia techniques of regional anaesthesia even high risk cases can be operated maybe a few months later than expected but within infancy period.

Surgical Treatment
Correction of radial club hand especially the more severe grades (which are incidentally commoner) requires a combination of non-operative and operative management that begins shortly after birth.

Early ( 0 to 3 months of age )
Treatment begins with counseling about nature and prognosis, when the child presents at birth to ensure a less drop- out rate and eradication of emotional and social stigma. Passive stretching of the taut radial structures is started at the initial visit. Stretching is performed at each diaper change and at bedtime. A stiff elbow with limited motion also is stretched during this time. Splint fabrication should be done with heat mouldable materials .Serial plasters are challenging until 3 months of age due to the extremely short working length of the forearm. When started at around 3 to 4 months of age however are certainly beneficial in maintain the suppleness and preventing wound complications post op.
Soft tissue distraction techniques [7], various fixator –distractor assemblies have been used with great enthusiasm for primary distraction both for late cases [13] and early in severe deformities. The author also prefers to use distraction with the mini ex fix for gr 3 and 4 radial club hands with angulation over 450. The principles, technique and results of the same have been highlighted in chapter [6].

Operative Methods
Early intervention takes advantage of the ability of the immature brain to adjust. Children with bilateral deficiencies that affect both the forearm and thumb require staged treatment to gain maximal use of the reconstructed limbs. Centralization of the wrist on the ulna to date remains a popular treatment to correct radial deviation. This procedure is performed in patients aged ideally 6 months of age before the onset of hand to mouth reflex vide Buck Gramko [8]. Surgery at this time allows for improvement in forearm length and provides a foundation for the development of motor function within the hand and for better cortical adaption in the growing immature brain.
Buck –Gramko [ 8] in his classical technique of Radialisation improved the ulnar lever arm by transferring the radial flexor and extensor to the ulnar aspect reversing the imbalance of the tight and strong radial musculo-tendinous units; which gained wide acceptance. This technique of tendon transfer is applicable and adequate to treat, grade 1 and 2 radial hemimelia cases where the deforming forces need to be converted to corrective forces in order to restore soft tissue balance at the wrist (Fig 4 a, b,c,d,e) . In an ideal world all radial club hands thus treated would not recur –but very often one encounters missing or short tendons especially in grade 3 and 4 radial dysplasia, and hence not available or adequate for a perfect rebalancing the deforming forces. As a pioneer in this field Prof. Buck Gramko also showed that excision of carpal bones and ulnar epiphyseal cartilage for grade 3 and 4 radial club hands ; is not only unnecessary, but its preservation leads to better range of wrist motion post surgery

Surgical Approaches
The skin incision and approach for open surgery has varied from author to author. Buck-Gramcko [8] and Lamb [3] favored the dorsal lazy S shaped approach (Fig 5a) this incision is not very aesthetic and runs opposite to the lines of langer and natural healing. Hence if there a wound dehiscence or hypertrophy it becomes a very unsightly scar .The disadvantages being a lack of radial skin in late and severe deformities and redundancy of the ulnar skin after correction, which needs unnecessary excision of good skin. Others have recommended a Z plasty (Fig 5b) along the concave radial border, and adding a longitudinal incision along the ulnar border overlying the ulno-carpal joint; the skin bridge between the two incisions however impedes access. Manske [1] used a single ulnar transverse ellipse incision (Fig. 5c) and so did Flatt but invariably both methods have been unable to solve the problem of unnecessary excision of ulnar skin.

Evans [9] in 1995 published his bilobed flap .He and his co authors have described a bilobed incision in which skin from the dorsum of the hand is transposed to the radial side to cater to the shortage, and the redundant excess is utilised to cover the defect now created on the dorsum.(Fig 6a,b).

There is a significant learning curve associated with this flap. In experienced hands the incision may heal as beautifully as shown in fig (Fig 6c, d) and may not even be seen if covered with a bracelet or watch or shirt sleeve (Fig 6e,f)

This too is fraught with a pitfall of superficial necrosis if the adipo-venous plane is violated. (Fig 7 a,b) The trick however is to keep the flap harvest as glabrous as possible taking care to maintain the perforator vessel feeding the flap as shown in (Fig 6c) and not skeletonising the ulna head as otherwise it may contribute towards physeal growth arrest of distal ulna [10]. The final closure too must be without tension. The advantages of the overall 360 degree exposure of the upper end ulna and carpus achieved with this flap and the ease of reduction, far outweigh its disadvantages, which can be easily managed with conservative treatment.
Pilz murdin [11] compared the 5 diffirent incisions described above .according to them the preferred practice in each region has by and large varied a lot however , now the bilobed flap is gaining popularity . The author personally prefers to have the best of both worlds , i.e. combine the advantages of distraction with a good surgical exposure and aesthetics and hence has been practicing the below highlighted method since almost 17 years now the mid term results of which are already published [16]

The main preoperative emphasis is placed on the status of soft tissues. Stretching and splinting of the taut radial structures is required prior to surgery. Failure to elongate the tight radial side limits the ability to centralize the wrist on the ulna. Preliminary soft-tissue lengthening with an external fixator is a option in cases recalcitrant to stretching, such as in older children or patients with a recurrent deformity.[7, 16]
Preoperative measurements of the degree of active and passive motion of the digits and wrist are recorded. Radiographs in the anteroposterior and lateral projection, including the elbow and hand, are obtained. The degree of ulnar bow is calculated from the lateral radiograph as the angle between the proximal and distal ulna. Angulation of more than 45° usually requires corrective ulnar osteotomy at the time of centralization to realign the forearm. Some authors however delay the ulna osteotomy as a second stage. This too is well accepted and is a prerequisite before limb lengthening .The sites, method and technique with fixation of ulnar osteotomy and results have been eluded to in detail in part II of the symposia

Surgical technique /Essential Steps
1. Incision and exposure of radial side defect with incision and approach. The author is well versed with the bilobed Evan’s flap (Fig 8) for grade 4and prefers to use the same in majority of cases. for grades 2 and 3 where a significant amount of dissection is required on the ulnar side, the author prefers the Manske ulnar approach (Fig 5 c) .For grade 1 and 2 radial club –hands where the skin shortage is not there and hence rebalancing is not required; the author usually uses bilateral Z plasties if the skin is tight or the Manske approach coupled with a mirrored radial transverse half incision like a hemi cincinnati incision used in club feet.
2. Identification of median nerve which may be tented over the defect and retraction out of harm’s way.
3. Identification and isolation of flexor carpi radialis along with the muscle belly and harvest over a stay suture :(if present) or hypoplastic and short especially where the thumb is well developed and the grade of dysplasia is mild.
4. Identification of extensor carpi radialis along with muscle belly and freeing its excursion by releasing the tight sheaths (differentiation of longus and brevis or two slips maybe deficient), and harvest over a stay suture.
5. Identification and excision of radial anlage, freeing the carpus from underlying fibrotic tissue.
6. Mobilizing the carpus to open up the radial side soft tissue upto neutral.
7. Proceeding with identification of extensor carpi ulnaris which is usually thick, redundant and curved over the head of the ulna and retracting it away.
8. Identification of the flexor carpi ulnaris which may be short and stubby but hypertrophied.
9. Open reduction of wrist joint at the cleavage of ulno-carpal junction by a sharp dissection. The recognition of this plane is aided either by a sharp needle or with performing wrist dorsiflexion and palmar flexion.
10. Passing a kirshner wire retrograde through the 2nd metacarpal and then back into the carpus after moving the carpus ulnar ward, to centre the wrist over 2nd metacarpal base where possible. Some authors resort to creating a notch in the carpal bed and the tapering edge of ulna to fit the mismatched sizes into each other. This was practiced and probably still is by a large section of orthopaedic surgeons still doing a single stage procedure in late and difficult cases. The argument for this being that the stability that this affords to the reduction is very much needed for preventing recurrence. However long term studies on ulna growth patterns have shown that this further reduces the growth potential of the hypoplastic limb.
The author strongly advices against the notch plasty and personally prefers to use pre-op distraction to aid with the reduction and preserve the growing cartilage at the wrist.
11. Careful reefing of the wrist joint capsule, particularly over the dorsal carpal area, and double breasting where required to prevent future volar subluxation. Do not proceed with the completion of tendon transfer unless wrist capsule closure is secured.
12. Completion of tendon transfer of flexor carpi radialis to flexor carpi ulnaris on volar aspect, and extensor carpi radialis to extensor carpi ulnaris dorsally. If the tendons falls short periosteal sleeves form the base of the metacarpals may be used or simple the tethering force on radial side may be released ad attached as ulnar ward as possible.
13. Skin and soft tissue closure without tension and above elbow slab over a well double padded dressing.

Post Operative Protocol
Immediate active and passive digital motion is initiated, along with measures to reduce swelling. The timing of K-wire removal is largely need based. At least 6 to 8 weeks of fixation is desirable till the carpus stabilizes. Some authors however recommend 12 weeks prior to removal; in practical terms it is usually difficult to maintain for this long and may invite complications like loosening and infection. Following K-wire extraction, a splint is made and removed for exercises, with gradual weaning from the splint over the next 4-6 weeks. A night-time splint regimen is encouraged until skeletal maturity is reached.
At some centers the tendon and/or bony procedures are performed simultaneously to better align the forearm and to balance the wrist. The extensor carpi ulnaris is used to increase its moment arm for ulnar deviation. Other less common options are discussed in part II of the symposia. Unfortunately, no method reliably and permanently corrects the radial deviation, balances the wrist, and allows continued growth of the forearm [12, 13]. Recurrence ,complications and long term problems are discussed in part II of the symposia. The maintenance of the carpus at the end of the ulna without sacrificing wrist mobility or stunting forearm growth remains a daunting task.[12, 13]

Follow-up and Results
Patients with radial deficiencies require follow-up into adulthood. The evaluation should include not only the status of the centralization but also any additional operative and non-operative needs [14,15]. The shortened extremity with diminished motion may not be able to accomplish certain functions. These tasks often can be carried out with the use of assistive devices. In addition, as the child ages, distraction osteogenesis may be an option to increase forearm length. As this review is being published , the authors personal experience with results of long term follow up with solutions to tackle the bowstring effect causing residual radial deviation and especially volar re-subluxation with follow up results of ulna growth and breadth are being analysed . The trends show much higher percentage of ulna growth almost above 70% and the diameter hypertrophy is way beyond expectation (Fig 9 and 10). This goes to prove that the earlier the procedure is done, the realigned carpus remodels the ulna dome to form a stable receptacle and support. Thus the growing cartilage is retained and it adapts to the function of the missing radius well.

Complications are common following centralization and can occur at the time of surgery or during the post-operative or follow-up period. Intra-operatively damage to the median nerve should be meticulously avoided by the use of careful blunt dissection and magnification loops during the surgery. The most important complication is compartment syndrome in the initial post op period and must be guarded against, by avoiding water tight skin closure, using loose well-padded dressing. Most other complications with our technique are minor and do not impact the overall outcome. These include pin-tract irritation and a transient diminution in finger motion. When using the distraction techniques instances of physeal distraction have been reported. These can be managed by immediate removal of fixator and immobilization in POP cast.
Recurrence is the most common source of failure after operative treatment, and the cause appears to be multi-factorial. Operative causes of failure include the inability to obtain complete correction at surgery, inadequate radial soft-tissue release, and failure to balance the radial deforming force, early k wire removal, poor postoperative splint use, and the natural tendency of the shortened forearm and hand to deviate as a natural consequence of the bow string effect of the long flexor tendons.
The application of sophisticated techniques, such as distraction osteogenesis and microsurgery [13], to the treatment of radial club-hand introduces additional potential complications, such as fracture of the regenerate bone, digital stiffness from lengthening, and vascular thrombosis of the microsurgical anastomosis.

Abstract

Clinical presentation of radial club hand deformity varies from mild hypoplasia to complete absence of radius. Various classification systems are described for radial club hand deformity as the treatment is based on the severity of affection. Treatment of radial club hand has progressed over the years from no treatment to conservative treatment to aggressive surgical correction. Recurrence after the surgical treatment is one of the challenging problems in this anomaly. History of treatment, advances and modifications of treatment, natural history and recurrence with respect to treatment have been described here.
Key words: Radial club hand, classification, treatment, recurrence


Introduction
In 1733, Petit first described radial club hand in an autopsy of a neonate with bilateral club hands and absent radii. If untreated, the deformity does not appear to worsen over time, but there is limitation in prehension and the hand is used primarily to trap objects between it and the forearm. Lamb found that the activities of daily living are not significantly affected in unilateral involvement, but bilateral involvement reduces the activities by one third. In radial club hand, ulna length at birth is known to be approximately 50-75% of the normal ulna length. This limb length discrepancy normally persists throughout growth. According to the literature, the ulna may finally be shortened by as much as 40% of its normal length.[1] There is general agreement favouring surgical correction at 3-6 months of age in children with inadequate radial support of the carpus.

Classifications:
Various classification systems have been described for radial club hand deformity. Most useful and currently accepted classification is modification of that proposed by Heikel.[2] In this classification system, four types are described.
Type 1: (short distal radius)
In this type, the distal radius epiphysis is present but is delayed in appearance. The proximal radial epiphysis is normal. The overall length of the radius is slightly less ,but the ulna is not bowed. (Fig.1)

Figure 1: Type 1 radial club hand

Figure 1: Type 1 radial club hand

Type 2 : (hypoplastic radius)In this type both proximal and distal radial epiphysis are present, but are delayed in appearance. Due to this there is moderate shortening of the radius and thickening and bowing of the ulna.(Fig. 2)

Figure 2: Type 2 radial club hand

Figure 2: Type 2 radial club hand

Type 3:(Partial absence of radius) Here , there is partial absence of proximal, middle or distal third of radius, distal being most common. Ulna is thickened and bowed. The carpus is usually radially deviated and unsupported. (Fig. 3)

Figure 3: Type 3 radial club hand

Figure 3: Type 3 radial club hand

Type 4 : (total absence of radius)
This is the most common type of radial club hand. Here ,there is radial deviation of the carpus, palmar and proximal subluxation, frequent pseudoarticulation with the radial border of distal ulna.There is shortening and bowing of the ulna. (Fig. 4)

Figure 4: Type 4 radial club hand

Figure 4: Type 4 radial club hand

Bayne and Klug [3] have described a radiological classification system with four types.
Type 1: Deficient distal radial epiphysis
Type 2 : Deficient distal and proximal radial epiphysis.
Type 3 :Partial aplasia of radius(present proximally)
Type 4 :Total aplasia of radius(complete absence)
Type 4 is the most common type of radial club hand.
A fifth type was added by Goldfarb et al [4] describing a radial dysplasia with participation of the humerus. James and colleagues expanded the classification by including deficiency of the carpal bones with a normal distal radius length as type 0 and isolated thumb anomalies as type N.
Variable degrees of thumb deficiencies are frequent with all patterns of radial club hand.(Fig. 5) Manske et al.[5] have devised a global classification system of radial longitudinal deficiency.(Table 1) They have included thumb and carpal abnormalities also in the classification. Carpal anomaly implies hypoplasia, coalition, absence or bipartite carpal bones .Hypoplasia and absence are more common on radial side of carpus and coalitions are more common on ulnar side. X rays must be taken beyond 8 years to allow for ossification of carpal bones.

History of Treatment:
The goal of treatment in radial club hand is to correct the wrist deformity, to maintain the corrected position, to provide wrist-like mobility, to preserve longitudinal growth capacity of ulna and to achieve an acceptable cosmetic result.
Non Surgical Treatment
Riordan [6] recommends applying a long arm cast as soon after birth as possible. The cast is applied in three stages using a technique similar to that used in clubfoot casting. The hand and wrist are corrected first and then the elbow is corrected as much as possible. The correction may be achieved in the infant but according to Milford, casting and splinting is often impractical in a child of age less than 3 months. Lamb [7] reported that elbow extension contracture can be improved by splinting with hand and wrist in neutral position. Current recommendation of treatment is to start from birth with stretching and splinting in order to lengthen the soft tissues and facilitate the reduction of the deformity. A large retrospective review of 446 patients including 137 patients managed non surgically and 309 patients managed with either a centralization or radialization procedure, found that those managed surgically had improvement in appearance and function, including improved alignment, range of motion and strength [8].

Surgical Treatment
Initial surgical treatment described by Bardenheuer was ulnar osteotomy to correct bowing and splitting of distal ulnar for insertion of carpus. Hoffa in 1890 performed a distal transverse osteotomy of ulna to simply realign the ulna. Albee [9] in 1919 attempted to create a radius with a free tibial graft. These surgeries did not give satisfactory result.
Centralization:
In 1894, Sayre [10] described the centralization technique that has now become the treatment of choice across the world. Sayre had described shaping of the distal ulna and notching of the carpus.
Although maintaining alignment, this procedure resulted in a high incidence of spontaneous ulnocarpal fusion with inherent loss of motion and reduced growth potential of the ulna. Many authors have subsequently modified this procedure in an attempt to decrease the potential morbidity while maintaining wrist position. Lidge [11] in 1969 introduced an improved method where ulnar epiphysis was preserved at the expense of central carpal bones that had to be resected. Although early results were good, late results were less satisfactory. Lamb recommended creation of carpal notch to stabilize the carpus on the ulna. He suggested depth of the notch to be equal to the transverse diameter of the distal ulna and this required removal of all of the lunate and most of the capitate. As against this, Watson et al.[12] suggested not to excise any of the carpus because of the possibility of affecting growth of the forearm. Buck-Gramcko (1985) and Bayne and Klug also suggested not to remove any of the carpus.
Different incisions and surgical approaches for centralization procedure have been described due to the problems of significant skin tension on radial side following ulna repositioning. Manske and McCarroll [13] preferred transverse ulnar incision, as described by Riordan, removing an ellipse of skin (Fig. 6)

Figure 7: S- shaped incision for centralization

Figure 7: S- shaped incision for centralization

Figure 8: Dorsal bilobed skin incision as described by Evans

Figure 8: Dorsal bilobed skin incision as described by Evans

Watson, Beebe and Cruz [12] preferred ulnar and radial z-plasty incisions to allow removal of the distal radial anlage which they believe is essential. Lamb (1972) [14] and Buck Gramcko (1985) described S-Shaped incision for better exposure. (Fig. 7)
Evans described dorsal bilobed skin flap to provide additional skin on radial side and take up excess on the ulna side of the wrist. This gives good access to wrist joint and surrounding soft tissue structures.(Fig. 8 )
DeLorme (1969) [15] first suggested intramedullary fixation of carpus on the ulna. Most authors now prefer to use K wire to secure alignment of long or index metacarpal with the ulna for at least 6 weeks. Still the recurrence rates are high. To overcome the recurrence tendency, additional procedures were introduced including collateral ligament reconstruction, soft tissue balancing by tendon transfer and leaving K wire for as long as possible (preferably several years) Bora et al [16]. recommended adjunctive tendon transfer. FDS from central digits was transferred around the postaxial side of the forearm into the dorsal aspect of metacarpal shaft. Hypothenar muscles were transferred proximally along ulnar shaft. ECU was transferred distally along the shaft of the metacarpal of little finger. However, this procedure failed to prevent 25-35 degrees of recurrent radial deviation. Bayne and Klug recommended transfer of FCU into the distally advanced ECU to help prevent radiovolar deformity.
Pre-centralization distraction:
Another recommendation to prevent recurrence was to use soft-tissue distraction before centralization (Fig. 9). Kessler [17](1989) described a technique to passively distract the soft tissue with an external fixation before centralization. Goldfarb et al reported on soft tissue distraction precentralization and noted that the centralization could be performed effectively and without tension after distraction, which averaged 6mm. Nanchahal and Tonkin [18] reported a similar experience, noting that carpal realignment was possible in 5 of 6 patients who underwent preoperative distraction, but only in 1 of 6 patients treated without distraction. Kanojia et al [19] reported similar experience with an external fixator and noted that early application can lead to completion of surgical treatment by 10 months of age in the vast majority of patients. Sabharwal et al[20] used Ilizarov for soft tissue distraction prior to centralization, considering it to be more comprehensive achieving physiologically sound distraction. Ilizarov has certain advantages over external fixator, as there is option of placing multiple bony anchors in different planes, application of translational hinges corresponding to the apex of the deformity. Bhat et al.[21] used MAC system (Multi axial correction) for correction of triplanar angulation, translation, rotation and limb length discrepancy. They found it useful especially in adolescent age group with previous failed soft tissue procedures. Dana et al.as well as Prokopovitch [22] and Kessler have reported small series of radial club hand deformities treated by external fixator application to gradually stretch the soft tissues to facilitate centralization.

Figure 9: Pre-centralization distraction using external fixator

Radialization:
Even with soft tissue distraction prior to centralization, there is high incidence of unsatisfactory results. Buck-Gramcko in 1985 developed a modified technique to improve the outcome. It is called ‘radialization’ [23]. In this technique, the hand is brought with its radial carpal bones over the head of the ulna and fixed with a K wire in moderate ulnar deviation to produce some overcorrection(Fig.10). Also ECR and FCR muscles are transposed to weaken the forces for radial deviation, thereby preventing recurrence while a better muscle balance is established. Both modifications tend to improve mechanical conditions which are prerequisites to maintain hand and forearm in proper relation. Also, in this technique, the resection of carpal bones can be avoided to help increase total arm length and improve range of motion. Buck Gramcko used this technique in 30 cases and found satisfactory results. With improved function and further growth, the distal end of the ulna became broad like a radius.

Figure 10: Radialization technique

Ulnar lengthening:
Ulnar lengthening was another technique used to increase forearm length, typically with the aid of a circular frame such that correction of the radial deviation can occur simultaneously. Farr et al [24] recommended lengthening procedure to be performed in school age children (8-10 years) to gain sufficient limb length for performance of ADL including perineal care in adolescence and adulthood. A second lengthening step may follow after growth cessation, depending on the functional outcome of the first procedure. They reported on 8 cases in 6 patients and noted that initial post surgical gains were not maintained and there was recurrence of radial deviation at an average 4 years follow up. Two major complications occurred, including an ulnar fracture after frame removal and insufficient regenerate during lengthening. Peterson et al [25] described 9 children who underwent 13 lengthenings after previous centralization procedures. The average gain in length was 4.4 cm (range 1.8-8.0 cm). All patients had at least one pin site infection that was treated with antibiotics. 4 patients required additional procedures including internal fixation and bone grafting for delayed union in 3 patients and wrist arthrodesis for recurrence in 1 patient. Yoshida et al[26] investigated the growth of the ulna after repeated lengthenings. After the initial lengthening, the average length improved from 57% to 89% of the normal side, but then regressed to 70% whereas after the second lengthening, the average length was 102% but regressed to 83%. Bone growth was markedly decreased after the second lengthening. Hence, when multiple lengthenings are performed the second one should be done after skeletal maturity (Fig. 11). Sestero et al [27] assessed the ulnar length and growth of 72 limbs treated either surgically or non surgically over 80 years. They found that non surgically treated extremities attained 64% of normal length, whereas patients who underwent surgery achieved 48% (notched centralization) to 58% (non notched centralization) of normal ulnar length. They also calculated an average annual ulnar growth of 2.6 cm after surgery, compared with 3.6 cm for patients treated non surgically. However, a recent study of 446 affected hands reported that surgical treatment was superior to conservative treatment in terms of appearance and function. Hill et al.[28] have suggested that full restoration of length is not necessary for this procedure to have a successful outcome. Recurrence of deformity after forearm lengthening has not been well described. Kawabata et al.[29] observed a tendency towards recurrence of ulna bowing and radial deviation in 4 of 7 patients, showing a final angular deformity of 19 degrees.

Figure 11: Ulnar lengthening using external fixator

Radial lengthening:
Matsuno et al [30] described 4 cases of mild (Bayne and Klug type I and II) radial club hand treated with radial lengthening and simultaneous soft tissue distraction between ulna and 3rd metacarpal. Three of the four patients required several lengthenings to correct the recurring discrepancy between the radius and ulna. Only two of the four patients had acceptable function and appearance after the multiple procedures. In one patient, lengthening was abandoned owing to severe bone absorption at the distal end of the radius.

Vascularised metastarsophalangeal transfer:
In 1920, an attempt was made to reconstruct the radius with bone graft to support the carpus. In 1945, non vascular epiphyseal transfer was attempted for treatment of radial club hand, but the results were disappointing, with disrupted ulnar growth plate and increase in limb length discrepancy. Also, there was inadvertent ankylosis / arthrodesis of wrist and loss of radial support. Vikki [30] reported the results of vascularised second metatarsophalangeal joint on 24 limbs with an average follow up of 11 years. The average radial deviation at final follow up was 280, the average active wrist total arc of motion was 830 and the average length of the ulna was 67% of the contralateral side. But complications were present in more than 50% of patients, including failure of the transfer and subluxation of the joint.

Post-operative assessment:
The outcome of various surgical procedures can be assessed by cosmetic appearance, total wrist arc of motion and certain radiological measurements as described by Manske et al.[13] HFA (Hand-FA angle) is the intersection angle between long axis of the long metacarpal and distal ulna, as measured on AP x-ray. Minus’ HFA refers to the hand and long axis of long finger metacarpal distal axis directed in ulnar deviation with respect to distal ulna. This is the more desired position. HFP (Hand FA position) refers to the distance in mm between base of little finger metacarpal and distal ulna. If proximal pole of little finger metacarpal was ulnar to the axis of distal ulna, the position (HFP) recorded as positive mm, a change in ulnar direction was considered an improvement in the position of hand. Ulnar bowing was defined as the angle between the intersection of the proximal and distal ulnar bi sector lines. The goal of treatment in radial club hand is to achieve slight overcorrection with ulnar deviation of hand and ulnar translation of hand and wrist at the end of treatment.(Fig. 12)

Recurrence:
Despite various advances in the surgical treatment of radial club hand, recurrence of radial angulation and ulna bowing is common. A possible cause may be the soft tissue, which remains pathologic after centralization or radialization. After consecutive lengthening and relative realignment of the forearm, the altered fibrous muscles and connective tissue lead to progressive rebowing of the ulna and a radial shift of the wrist. Precentralization distraction aids in soft tissue balancing at the time of centralization, but it is unknown whether the technique will improve maintenance of alignment with longer follow-up. Deformities noted to be more severe preoperatively were more likely to recur. Also, recurrence was associated with young age (less than 12 months) at index procedure and immediate post operative radial deviation position. It is advisable to inform the parents (and patients) at the time of centralization, that the deformity may recur. Lamb reported 3 recurrences of volar angulation after 31 centralization procedures [14]. Damore et al[32] reported that the mean total angulation (radial deviation and ulnar bow) improved from 830 before centralization to 380 after, but recurred to 630 radial deviation at a mean 6.5 years after centralization. Geck et al [34] performed survivorship analysis of 29 radial club hand treated with centralization or radialization, with an end point of revision surgery for recurrence. At 5 years, one third of patients presented with a recurrent deformity that was subsequently treated by revision. According to Pike et al.[33] post centralization recurrence of radial angulation to greater than 450, an inability to actively extend the wrist to within 250 of neutral (i.e. 250 of flexion) or both, are considered as indications for re-surgery. Treatment of recurrent deformity after centralization is problematic; repeated centralization is likely to fail again because of the instability of the hand and carpus at the end of a single forearm bone. The preferred treatment after a failed centralization procedure is ulnocarpal arthrodesis in skeletally mature or an epiphyseal arthrodesis when the distal ulna physis is still open. Epiphyseal arthrodesis showed no disturbance in extremity growth when performed in skeletally immature extremities when the surgical principles for preserving the epiphysis were carefully followed. There is always a concern about the irreversible feature of a wrist fusion in a young patient. To address this concern, a temporary arthrodesis is offered to patients to allow the patient to make an informed decision, the wrist is stabilized in surgery with percutaneous K wires holding the ulno-carpal joint in the anticipated position of fusion. If the patient likes the position, epiphyseal arthrodesis is performed in 1 to 2 weeks, if the patient does not like the position, K wires are removed and the wrist returns to its former position.
There are several treatment options for radial club hand, including non surgical management; centralization, radialization or ulnarization; ulnocarpal arthrodesis; soft tissue procedures including distraction; ulnar lengthening; and vascularized second metatarsophalangeal joint transfer. The most common procedure performed currently is soft tissue distraction followed by a wrist realignment procedure such as centralization, or radialization. Ultimately, a procedure is needed that can correct and maintain the deformity, yet permit growth with a low complication rate.

Abstract

Radial club hand is one of the common upper extremity congenital deficiencies involving partial or complete agenesis of the radius. It is associated with a deformed and subluxed wrist with varying degrees of thumb hypoplasia. Associated soft tissue defects and systemic defects are often found. Though the exact etiology is yet to be ascertained, newer research tends to highlight the importance of the apical ectodermal ridge and its proper development is vital to the formation of the normal forearm structure. The pathoanatomy of the forearm involves a short or absent radius with bowed ulna with a wide spectrum of variability in the formation of carpal bones, preaxial muscles and associated neurovascular structures. Certain syndromes are known to be commonly associated with radial club hand and these need to be specifically investigated before proceeding with treatment of the club hand.
Keywords: radial club hand, embryology, associated syndromes


Introduction
The term radial club hand is applied to children born with complete or partial absence of the radius or the preaxial border of the upper extremity. This produces the characteristic radial deviation of the hand (“mannus valgus”), which is similar to a clubfoot deformity and hence the term “radial club hand”. It is also termed as congenital longitudinal deficiency of the radius and is one of the common congenital upper limb birth defects. Its incidence varies from 1 per 30,000 live births to about 1 per 100,000 [6]. It is ten times more common than ulnar deficiencies and bilateral involvement is seen in 38 – 58% of cases.

Embryology
The hand develops as an upper limb bud during the 4th week of gestation as a mesenchymal condensation covered with ectoderm. The mesoderm part gives rise to muscle, tendon, nerve and bone, while the ectoderm differentiates to form skin, hair and nails. These differentiation elements proceed from proximal to distal as the limb bud elongates.
The development of the limb bud progresses along three axis: proximal to distal, anterior to posterior (i.e. radial or ulnar since the fetal upper limb rotates during development) and a ventral to dorsal. Further differentiation within the limb bud is guided by “organizing tissues” viz. apical ectodermal ridge, zone of polarizing activity and the dorsal ectoderm. Associated molecular pathways include SSH (sonic hedgehog), fibroblast growth factors and Wnt proteins [3]. Wnt proteins are a family of highly conserved secreted signaling molecules that regulate cell to cell interaction during development and adult tissue homeostasis. At 33 days of gestation the hand resembles a paddle without individually distinguishable digits. The five rays of metacarpals and phalanges get defined by 41 days. A process of programmed cell death leads to separation of the five rays into four web spaces between 47 days and 54 days. By 7 weeks the mesenchymal condensation that will eventually produce each of the bones of the carpus becomes evident, while the major appendicular bones get defined by 8 weeks. At the end of the embryonic period all future bones are cartilaginous models of their adult form and distal phalangeal tufts begin their ossification [5].

Etiology
In the 19th century, the etiology of radial club hand was theorized to be either a congenital absence or an acquired defect secondary to syphilis. Yet another theory spoke of abnormal pressure upon the embryo along the radial bud between the third and seventh week of gestation in 1895.
No specific etiology has yet been identified though genetic and environmental factors have been implicated. Most cases seen are sporadic in nature with no specific implicating factor 4. Lamb, in 1977, reviewed 117 radial club hands in 68 patients over a 15 year period, including those exposed to thalidomide (26 cases) and concluded that damage to the apical ectoderm on the anterior aspect of the developing limb bud led to the deformity [7]. Most authors who studied embryology of radial hemimelia by consensus are in favor of insult to the apical ectodermal ridge (AER). This structure is a thickened layer of ectoderm that directs differentiation of the underlying mesenchymal tissue and limb formation [2].Therefore, a defect of the AER is the most probable cause of radial club hand, with the extent of deformity related to the degree and extent of the AER absence [3].Removal of a portion of the AER in chick embryos has produced anomalies similar to radial club hand.
Newer evidence has postulated that decreased limb volume with intact SHH expression can be the causative mechanism. This leads to preservation of the posterior (ulnar) elements, while causing an overall decrease in limb length. Researchers have achieved some success in duplicating similar limb deficiencies in animal models by progressively reducing the apical ectoderm ridge and its associated fibroblast growth factors [1, 2]. Different molecular pathways influence cell growth and apoptosis, thus changing the limb volume during the growth and development of the limb bud. Simultaneous development of other organ systems are often affected leading to various associated syndromes like Holt Oram syndrome, TAR syndrome, Fanconi anemia and VACTERL abnormalities.

Patho-anatomy
Four types of radiological radial dysplasia are evident:
1) Short distal radius: radius is present but short distally. The shortening is due to delayed appearance of distal radial epiphysis and its deficient growth. The thumb is hypoplastic and radial carpals may be absent or hypoplastic.
2) Hypoplastic radius: radius is short and ulna proportionately bowed. Both proximal and distal radial epiphyses have growth deficiency
3) Partial absence of radius: radius is partially absent in its distal middle or proximal third. The ulna is short, thickened and bowed. The carpus is unsupported and the hand rolls around the distal end of the ulna. Hand function is usually poor. (Fig. 1)
4) Total absence of radius: most commonly encountered sub type. There is no radius at all, the ulna is bowed and hand function is poor. (Fig. 2)

Associated abnormalities
a) Local:
Bony: The degree of pre-axial deficiency varies from thumb hypoplasia to complete absence. It may be associated with absence of carpal bones especially the radial ones. The carpal deficiencies are related to the extent of thumb deficiency. For example with an absent thumb the radial carpal bones are absent, while with a complete but hypoplastic thumb, the scaphoid and lunate are hypoplastic. The patterns of thumb hypoplasia are given in Table 2 [6]. Whole or part of the radius may be absent and in severe cases the elbow joint may be poorly formed. The forearm is usually short (50 – 75%) as compared to a normal contralateral forearm [9].
Muscular: these vary in proportion with the skeletal defects. The preaxial muscles (extensors arising from the lateral epicondyle) are frequently deficient. The brachio-radialis, usually present in 50% of cases, inserts into the radial side of the hand and acts as a strong tethering deforming force. The ECRB and ECRL are usually deficient. The thenar muscles are defective in proportion to the thumb deficiency. The post axial muscles (arising from medial epicondyle – pronator teres, FCU, FCR) though well differentiated have abnormal insertions and act as radial deviators of the hand.
Neurovascular: the radial artery is usually absent. The Anterior interooseous artery (arising from the ulnar artery, which is usually normal) supplies the radial part of the forearm. The Ulnar and Median nerves are usually unaffected. The superficial branch of the radial nerve is deficient from the level of the lateral epicondyle. Its function is replaced by a branch of the medial nerve, which runs a course parallel to the absent dorsal cutaneous branch of the superficial radial nerve.
Systemic: In approximately 25% of patients, associated cardiac, gastrointestinal and renal abnormalities may be found. The most frequently associated syndromes include Holt – Oram syndrome, Fanconi anemia, Thrombocytopenia Absent Radius, and VATER (vertebral segmentation deficiencies, anal atresia, Tracheo – esophageal fistula, renal abnormalities and radial ray deficiencies). Trisomy 13 and 18 are also known to be associated with radial deficiencies. In cases with fetal valproate syndrome there is usually an associated syndactyly of the 2nd or 3rd web, which hampers the results of subsequent pollicisation (Fig.. 3).(personal observation of authors )

Figure 3 c: Clinical picture of child with fetal valproate syndrome showing syndactyly of 2nd web space and hypoplastic thumb and index finger

In addition to these conditions, a variety of associated musculoskeletal deformities appear sporadically. These include cleft palate, clubfoot, kyphosis, scoliosis, torticollis, and rib deformities. For most of the time in clinical practice the following syndromes are most often encountered by the surgeon and hence are listed in tabular form.
Investigations with relation to syndromes.
Children with VACTERL syndrome warrant additional evaluation for spinal abnormalities, such as congenital scoliosis, and require radiographs of the spinal column. Children with VACTERL syndrome often appear similar to children with Fanconi anemia; they are of small stature, have feeding difficulties, and have similar musculoskeletal anomalies. Therefore, a chromosomal challenge test is warranted in a child with a presumed diagnosis of VACTERL syndrome.
Hematological, The most devastating associated hematological condition is Fanconi anemia. Children with Fanconi anemia do not have signs of bone marrow failure at birth; therefore, the diagnosis is not initially apparent. The majority of children experience signs of aplastic anemia between the ages of 3 and 12 years (median age of 7 years). However, a chromosomal challenge test is available that allows detection of the disease prior to the onset of bone marrow failure. This assay tests a sample of the child’s lymphocytes to diepoxybutane or mitomycin C, which cause chromosomes within Fanconi anemia cells to break and rearrange. In contrast, lymphocytes in unaffected children are stable to these agents.
Because bone marrow transplant is the only cure for Fanconi anemia, this prefatory diagnosis is crucial for the child and family. Early diagnosis provides ample time to search for a suitable bone marrow donor or consider preimplantation genetic diagnosis (PGD). PGD is a sophisticated technique that involves in vitro fertilization, sampling of the blastocytes to ensure human leukocyte antigen (HLA) similarity without Fanconi disease, and re-implantation until birth. At delivery, cord blood is harvested from the newborn and used as a source of stem cell transplant for the affected sibling. Since PGD takes time, early detection via a chromosomal challenge test is critical and may ultimately save the affected child.

Summary
The management of radial hemimelia is by no means easy, it is a subject which is still unclear as regards to its exact embryology and causation and is a potent field for considerable research. Some day when all the questions are answered we may have a complete understanding of the cause and hence this may lead us to the optimal solution for this varied deformity.

The evolution of treating this anomaly is a journey of learning; learning to reform or substitute for nature’s glitch: one of changing paradigms in treatment with a constant reality check at every juncture in terms of complications and recurrence.
The story about the deformity radial hemimelia, radial dysplasia, radial dysmelia or radial club hand as we popularly refer to it is neither new nor too contrasting if we study it carefully looking both backwards and forwards. Paediatric orthopods, hand and plastic surgeons alike have been laboring painstakingly to better their own efforts at recreating the missing elements over the centuries to its contemporary garb (Fig. 1). It is one of those complex congenital anomalies the exact genesis of which is not completely clear but the treatment of which sees a confluence of three major branches of reconstructive surgery.

Hence we have put together a special anniversary issue, the best known thinkers and experienced surgeons on the Indian scenario as well as extra special contribution from Boston children’s hospital as bonus: masters who are adept at their techniques and have penned down words of wisdom in great detail in the forthcoming chapters. Since the subject is multifaceted, vast and complex we have divided it into two issues.
Part 1 which deals with the evolution ,treatment and preliminary surgeries in infancy and toddler age group and part 2 which deals with the early and late childhood treatment of radial hemimelia and other issues. I would urge the reader to pay attention to the structuring of both these issues and delve into the depths of each sub topic ,as it has been put together with a great deal of thought .
One of the major milestones surely has been the rational concept of radialisation, early surgery, retaining growing cartilage and early pollicisation and that is why it has withstood the test of time. Distraction techniques have been another value addition to the changing face of modern day radial club hand treatment. I congratulate Prof Bhaskaranand and Dr Binoti Sheth for an exhaustive chapter about natural history, treatment and long term outcomes. The focused section on etiology and pathogenesis is albeit a little narrow in scope but by no means trivial and both the lead authors Dr Anirbaan Chaterjee and co-authors have done a commendable job of the same.
The chapter on pollicisation is both a brilliant compilation of literature review as well as lucid technique guide for the senior and junior surgeons alike; a task not as simple as it seems to achieve. Dr Thatte takes the reader elegantly through a surgical technique that truly defines the word reconstruction. The succinct expose by Dr Don Bae offers a thought provoking fresh perspective paving the way for yet another change in the management of this multi focal deformity. Our issue would have been incomplete without these two astute writers.
Before signing off I would ponder on the thought –whether in future genetic engineering and the much hyped concept of stem cells can bring about a dramatic change? My humble submission is that if it has taken centuries for surgeons to a arrive at as complete an approach as possible to the surgical management ,it would be wishful thinking that one can start playing God so soon in the near future.

People forget how fast you did a job—but they remember how well you did it.
–Howard W. Newton
And finally as the guest editor in chief in my chapter, I have endeavored to recount in a simplistic fashion the approach and technique that works best in my hands as that is the bottom line and to my mind a decision that matters the most clinically.

Dear Colleagues,we are glad to present to you the First Anniversary issue of International Journal of Paediatric Orthopaedics (IJPO). First anniversary is a landmark event in history of a Journal. If a journal runs successfully for one year, it reflects that the journal is here to stay. One year is the basic temporal unit after which most of the indexing of the journal arrives and the academic quality of the Journal is evident. IJPO has a consistent history of publication with no issue skipping and every issue having good number of articles. IJPO has started receiving articles from nay countries including UK, Mexico, Canada, India, USA and also Japan. This shows that the authors have developed faith in the journal. This has greatly encouraged us to take IJPO to greater heights. The review process is stringent and effective with each article undergoing blinded peer review. These standard are maintained along with best publishing practices which helps IJPO earn good reputation. We are happy to announce that IJPO has been accepted for Indexing in Index Copernicus thus making it eligible, as per Medical council of India, to be called as indexed Journal.
IJPO was started with the aim to bring practice based practical knowledge to the readers along with high quality research papers. With this aim we ran expert symposia’s in each issue in first year and we will continue this tradition in future. The present issue contain symposia on radial club hand compiled and edited by Dr Rujuta Mehta. We thank her for an excellent effort in selecting authors for the symposia and editing each and every article. This symposia will run in two issue as the number of articles were more. In future too we would love to have much more detailed symposia where every aspect of the selected topic can be comprehensively covered. We invite more colleagues to join us as Guest editors at IJPO.
In this issue we have started a new trend of interviewing legends of paediatric orthopaedics. For the first interview, Dr Ashok Johari’s name was unanimously selected and Dr Sandeep Patwardhan and Dr Ashok Shyam interviewed him in Pune. The interview has come up as an excellent piece of literary work which traces Dr Johari’s journey of becoming a paediatric orthopaedic surgeon. The interview is also to be published in two parts with first part included in this issue and second part in forthcoming issue. These interviews will help us get a glimpse of life and times of the legends and to learn from them. We will continue this tradition of interviewing exceptional personalities in paediatric orthopaedics in every issue of IJPO.
Lastly, IJPO has initiated an active participation in research. A journal need not only be a passive platform for publishing research but it can also be an active platform which can be used to conduct studies. IJPO team has liaised with Trauma Registry app developed by Indian Orthopaedic Research Group to start a supracondylar humerus fracture registry. More on the registry is covered later in the issue but basically this aims to collect epidemiological data as far as paediatric supracondylar humerus fractures are concerned.
We hope these new features will attract more authors and readers to IJPO. We will continue to work hard on developing new formats of articles and publications for IJPO and also focus on improving the indexing of IJPO in next one year.
