Abstract

Background: In India, clubfoot is quite commonly seen. Consanguineous marriage is one of the etiological factors associated with clubfoot deformity. Consanguineous marriage is a fairly common sight, especially in rural areas in India. As there is no study from India which mentions relationship of consanguinity and clubfoot, the present study was conducted.
Aim: The aim of the study was to find if there was any significant correlation between relationship of consanguinity and clubfoot, and divide them based on degree of consanguinity.
Material and Method: The study was conducted from 2010 to 2015 at tertiary institute. The total number of cases which were considered of idiopathic variety of clubfoot was 406. Out of these, the cases were divided into presence or absence of consanguinity, and also the degree of consanguinity. A detailed history about consanguinity was taken.
Result: According to the data and classification, 140 patients were born out of consanguineous marriage. This states that about 34.4% of the cases had consanguineous marriage. After classification into degrees, it was found that there were no cases of first degree consanguinity, 25 cases of second degree and maximum number of cases i.e. 115 cases with third degree consanguinity.
Conclusion: Thus it can be concluded that consanguinity is significantly seen in cases with idiopathic clubfoot. So, we need to create awareness regarding consequences of consanguineous marriages, particularly in rural and developing areas.

Introduction
India, being a culturally diverse nation, with various religions and castes, is a land with people following different customs. With various backgrounds, follow various belief systems and mind-sets. People from rural places, tribes, and low socio-economic areas, believe that marriage of their son/daughter within the family would make them safer and secure in life and thus getting them married to their relatives.
Clubfoot is one of the commonest congenital anomalies seen in orthopaedic practice. Prevalence of Clubfoot in Asian countries is about 1.5/100 children.
According to a study from India, in Sindhudurg District of Maharashtra, India, the prevalence of Clubfoot is 1.8/1000 new borns. (1) One of the etiologies mentioned in the literature of Clubfoot, is consanguineous marriage. Although Clubfoot is quite common in India, there are very few studies mentioning the prevalence of consanguinity in Clubfoot cases.

Aims
To determine the prevalence and degree of consanguinity in patients with idiopathic congenital talipes equinovarus.

Material and Method
This study was done in a tertiary care hospital, with a dedicated Pediatric Orthopaedic unit. We do see large number of cases here, of clubfoot, coming from backward areas, rural places and low socio-economic statuses, where the literacy and education is low.

We collected data from the year 2010 to 2015, of clubfoot cases that came to the hospital for advice and treatment. In all these cases, we selected the cases of idiopathic clubfoot. They consisted of treated and untreated cases of idiopathic clubfoot. At the time of consultation, detailed history of child with perinatal period, and also marital history of parents was taken. Any consanguineous marriage found in the history was noted and mentioned in detail.

We omitted all the cases other than idiopathic variety, such as Arthrogryposis, Meningomyelocele, and Syndromic cases.
We included all the cases of treated or untreated cases of idiopathic clubfoot and divided them by presence or absence of consanguinity. Then the cases with consanguineous marriage were further classified into degrees.
For classification of degrees of consanguinity, we referred to the NHS National Genetics and Genomics Education Centre (4) through their website (www.geneticseduction.nhs.uk)
From this source, we found information about classification of consanguinity into degrees. Degree of consanguinity is determined by the degree of relationship between the two individuals. That in turn is determined by the shared amount of genes in the relatives. As half of the genes in a person are inherited from each parent, and shared with the sibling, marriage with parent, sibling or child, is first-degree consanguinity. Sharing one-quarter proportion of genes with aunt/uncle, niece/nephew, grandchild/grandparent, marriage with one of these relations is second-degree consanguinity. The third degree of consanguineous marriage is with the relations sharing one-eighth proportion of genes, i.e. with first cousins, or great grandparents.
Following is the classification of consanguinity into degrees:
First Degree: marriage with Parent, Child, or Sibling.
Second Degree: marriage with Aunt/Uncle, Niece/Nephew, Grandparent/Grandchild
Third Degree: marriage with First Cousins.

Result
From the years 2010 to 2015, at our institute we saw 457 cases of clubfoot. Out of these, 39 were cases of non-idiopathic variety. So we excluded them. Out of the remaining 418 cases, 240 cases had come at neonatal age and 178 cases had come at different ages, for treatment. Out of these 418 cases of idiopathic clubfoot, 12 parents were not willing to share their marital history. So, after excluding them, our final data comprised of 406 cases, which were then classified into degrees of consanguinity.
So with the final sample size of 406 cases, 230 cases were presented to us at neonatal ages while 168 were late presenters (Age 3 months to 10 years).
In this study, out of 406 cases, there were 272 males and 134 females. Out of these patients, 282 had unilateral clubfoot, and 124 cases had bilateral. With respect to consanguinity, there were 140 children born out of consanguineous marriage. This accounts to about 34.4% of patients with consanguineous marriage of parents. According to the above-mentioned classification, there were 0% cases of first-degree consanguinity, about 18% i.e. 25 cases with second-degree consanguinity. Majority of them 82% i.e. 115 cases had third-degree consanguinity. This way, the commonest degree was the third, and within the third degree of consanguinity, all the marriages were found to be between respective children of brother and sister.
Consanguineous marriages are more prevalent in rural areas than urban. These have been very commonly associated with low age at marriage, low educational level of mother, and low occupational status of the father.
Association of consanguinity and pediatric disorders is well established. Parental consanguinity has been linked with various risks including stillbirths, perinatal mortality, congenital birth defects [DDH, CTEV], malformations, mental retardation, and neonatal diabetes mellitus.
Parental consanguinity increases the autosomal recessive conditions through the expression of the recessive deleterious alleles, especially in the offspring of first-degree consanguineous marriages.
In our study, we have attempted to establish the correlation of clubfoot and consanguineous marriage. In previous study made by Shrinivas and Nataraj (3) they have established consanguineous marriage as one of the factors causing clubfoot.
Our study demonstrates, that almost one-third of the cases of CTEV that came to our outpatient clinic have consanguineous marriage of parents. These findings are similar to the study done by Sahin at al. (2), which demonstrated similar percentage of cases of clubfoot and consanguinity.
There is no direct relation of sex or number of feet affected (unilateral or bilateral), with consanguinity.

Conclusion
The result of the presented study reveals that there is a significantly high proportion of consanguinity in clubfoot patients. There is an urgent need to inform the people, properly about the anticipated deleterious effects of inbreeding in societies where inter-relation marriage is widely practiced. Further etiological studies that look into the association of consanguinity and clubfoot are needed to support the finding and clarify the significance of such an association.

Abstract

Background: The management of idiopathic clubfeet with Ponseti method of casting has been well outlined in literature. However management of non-idiopathic clubfeet, like the ones associated with arthrogryposis or myelomeningocele, has been challenging. Various treatment modalities including casting, soft tissue releases, bony procedures and talectomy have been attempted, either in isolation or in combination, with variable results. The aim of the current study was to perform a comprehensive review of the literature related to the classification and management of non-idiopathic clubfeet. Recent literature has shown benefits of a trial of Ponseti method of casting for all non-idiopathic clubfeet. Most of these clubfeet, however, would require surgical treatment due to either insufficient correction or recurrence. We attempt to provide, based on the review of literature and our experience, a treatment algorithm to help with the management of complex, non-idiopathic clubfeet.
Keywords:Non-idiopathic clubfoot, CTEV, Ponseti, arthrogryposis, myelomeningocele.

Introduction
With the success of Ponseti casting technique, the management of most congenital talipes equinovarus deformity or idiopathic clubfeet, has been standardised. The management of non-idiopathic clubfeet, however, continues to be challenging. These non-idiopathic clubfeet are associated with many neuromuscular and congenital syndromes, the most common of which are arthrogryposis and myelomeningocele (Table 1). The diagnosis of the underlying condition associated with clubfeet is important as it can affect management and help predict prognosis. These feet have been considered more rigid with a higher rate of recurrence compared to idiopathic clubfeet. In the past, they have been considered to be resistant to non-operative treatment and have been treated with multiple surgical procedures including extensive soft-tissue releases and radical bony surgeries .
The purpose of this study is to perform a comprehensive review of the existing literature, review our experience and provide guidelines for management of non-idiopathic clubfeet. The article would first describe the distinct features of common conditions associated with non-idiopathic clubfeet and would discuss the need for special considerations, if any, in their orthopaedic management. This would be followed by general principles and treatment algorithm for management of non-idiopathic clubfeet.

ARTHROGRYPOSIS
Arthrogryposis is derived from the Greek words, joint (arthron) and hooked (grupon). It is a condition of non-progressive contractures of two or more joints often resulting from fetal akinesia . Arthrogryposis is not a specific diagnosis but a clinical finding characteristic of more than 300 disorders .
Clubfeet in arthrogryposis are usually stiffer and the deformities are more severe than idiopathic clubfeet. The skin is thin and smooth, muscles are pale and thin and often replaced by fat and fibrous tissue, ligaments and capsular tissues are thickened and tight, and articular surfaces are abnormally shaped with absent skin creases around the joint. Deformities are usually bilateral but rarely symmetrical. Deformities are not progressive but untreated deformities become more rigid with growth . There is a resistance to correction and also a tendency to recur. Of the various types of arthrogryposis, clubfeet in amyoplasia have severe deformities, are stiffer, more rigid and more resistant to treatment than in distal arthrogryposis. .
Concomitant contractures of the knee and/or hip pose a unique problem to clubfeet management in arthrogryposis . The knee could have a fixed deformity in extension (subluxated) or in flexion. During casting for clubfeet, a knee with an extension deformity can cause slippage of the cast and hence loss of correction. Simultaneous gradual correction of the knee and the foot in cast could be attempted. Failure of closed treatment of knee extension contracture may require surgical intervention. Simultaneous surgery of the knee (e.g. quadricepsplasty) and cast treatment of the clubfoot pose a challenge as well, as the knee would require early postoperative mobilization and this may compromise the correction of the foot. When knee has flexion contracture, soft tissue stretching/release or corrective extension osteotomy could be done after correction of clubfoot.
Hip joints in arthrogryposis are often subluxated or dislocated. These dislocations are often teratogenic and can rarely be treated by closed reduction. When both hips are affected, they are best left untreated and when unilateral, closed or open reduction should be attempted in the first few months.
Children with arthrogryposis often require multiple corrective surgeries and hence repeated anaesthesia. Airway access could be challenging and fibre optic intubation should be considered in such circumstances. Intravenous access may be difficult due to presence of tense skin and less subcutaneous tissue. Intra-operative positioning may be difficult due to multiple contractures. Perioperative respiratory issues and malignant hyperthermia should be considered in these children .

Diastrophic Dysplasia
Diastrophic dysplasia is an autosomal recessive disorder characterised by short stature, multiple joint contractures, cervical spine scoliosis, hitch hiker’s thumb, cauliflower ears and severe clubfoot deformity. Similar to arthrogryposis, clubfeet are usually rigid, difficult to treat and may be co-existent with hip and knee contractures. Surgical correction pose difficulty in these feet due to distorted anatomy. Recurrences after initial treatment are common and may require extensive releases and/or talectomy .

Freeman Sheldon Syndrome
This is a type of distal arthrogryposis characterised by ‘whistling mouth facies’, short stature, hand deformities in form of ulnar deviation and thumb in palm and rigid clubfeet.

Neurogenic Clubfoot
Clubfeet occur in 30-50% of spina bifida patients. It is most commonly seen in lumbar lesions at the level of L3-L4 and above. . The level of lesion should be identified as it would affect the functional motor level and hence the ambulatory capacity. In a potential walker, the aim is to have a plantigrade foot that can weight bear; in a non-walker, the aim is to have a braceable foot to rest on the footpads of a wheelchair. Presence or absence of foot sensation should be assessed. The deformity in neurogenic feet can be attributed to varied causes including intrauterine malposition, muscle imbalance, spasticity and/or fibrotic contractures. These feet are rigid, difficult to treat and have a high risk of recurrence. There is an increased risk of pressure sores and skin breakdown due to altered or absent sensations. Physeal injury is not uncommon with manipulations. There is a high risk of fractures in these children undergoing manipulation which might not be diagnosed early due to absence of pain. There may be delayed healing of wound after surgery.
Casting in these children with myelomeningocele should be used only to maintain the correction and not to correct the deformity. Insensate feet make it difficult to identify pressure sores. Casting and manipulation should be stopped if swelling, sores or ulcers develop.

Mobius Syndrome
Mobius syndrome is a rare non progressive congenital neuromuscular disorder. It is characterised by palsy of the sixth/seventh cranial nerve and malformation of orofacial structures and limbs. Typically they have absent abduction of both eyes. Clubfoot is the most common deformity of the foot. Diagnosis should be suspected when multiple cranial nerve dysfunction exist with clubfeet.

Streeter’s Dysplasia
This is a disorder of fetal development in which the amnion separates from the chorion and forms bands which encircle limbs . Part of the limb distal to the band may be amputated, anomalous or normal. Incidence of clubfeet with constriction bands is 12-56% . These children may or may not have a neurological deficit on the involved side. Neurologic deficit has been found more commonly with zone 2 bands (band between knee and ankle) and grade 3 severity i.e. (reaching up to the level of fascia compromising distal circulation) . Clubfeet with constriction bands are rigid, respond poorly to conservative treatment and often require soft tissue release . Feet with neurological deficit have been more resistant to treatment by earlier authors and require more number of surgeries than ones without a deficit .
In case the constriction band causes circulatory compromise, emergent release should be done. All other bands may be released in a staged manner after correction of clubfoot. Paralytic feet may require tendon transfer depending on the involvement.
Down’s Syndrome
Down’s syndrome is the most frequent trisomy (chromosome 21). It is characterised by hypotonia and hyperlaxity, mental retardation, congenital heart disease, atlanto-axial instability, habitual dislocation of patella and hip and genu valgum. Though typical foot deformity due to hyperlaxity has been pes planus with metatarsus adductus, occasionally soft tissue contracture around the ankle, subtalar and mid-tarsal joints present as clubfoot . In spite of generalised ligament laxity, these feet are resistant to non-operative treatment and often require surgical treatment . These feet, however have a tendency for overcorrection and calcaneovalgus deformity following treatment due to generalised hyperlaxity.
Pre-operative evaluation should include cardiac evaluation and cervical spine x-rays to screen for cervical spine instability.

Larsen’s Syndrome
Larsen’s syndrome is a rare congenital connective tissue disorder caused by mutation in gene encoding filamin B (FLNB). It has genetic heterogeneity with both autosomal dominant and autosomal recessive patterns. It is characterised by flat facies, cardiac defects and varied musculoskeletal Issues that include joint hypermobility, vertebral anomalies, recalcitrant dislocations of multiple major joints and clubfeet. Early detection of the syndrome is important for management decisions and prognostic counselling. Management of cervical spine instability should be a priority in these children. When hips, knees and feet are involved, treatment of the knee should be a priority. Clubfeet in these children should be treated by conservative method soon after birth and surgical treatment should be postponed until knee dislocation is corrected . Due to hyperlaxity, care should be taken to prevent overcorrection of these feet as they can often develop calcaneovalgus deformity. Hip dislocation, if bilateral, should be managed by careful neglect due to poor results of surgical treatment.
Preoperative assessment should include thorough respiratory, cardiac and neurologic evaluation. Lateral cervical spine x-rays in flexion and extension should be mandatory prior to anaesthesia to evaluate cervical spine instability which is common in this syndrome.

Principles of Treatment
Conventional non-operative treatment has been considered ineffective in cases of non-idiopathic clubfeet . Serial manipulations and casting of these feet often resulted in incomplete correction and frequent recurrences. Previous literature thus focused on the operative treatment of these feet, with most feet requiring multiple procedures. Soft tissue releases, however, also resulted in recurrences and required brace wear till skeletal maturity . Due to high incidence of failure of soft tissue releases, talectomy has been considered to be the procedure of choice as a primary surgery as well as in cases of recurrence .
Ponseti popularised the method of serial casting to correct idiopathic clubfeet with excellent results. In non-idiopathic feet Ponseti method decreases the severity of deformity and hence decreases the need for extensive surgery. Trial of Ponseti method should be the first line of treatment for all clubfeet, irrespective of their etiology. In recent literature, short term results of Ponseti method for correction of non-idiopathic clubfeet have been encouraging (Table 2). Most of these feet were Dimeglio grade IV or Pirani grade 4 or above . More number of casts were required than idiopathic feet, however good initial correction was achieved in most non-idiopathic feet . Arthrogrypotic feet being more rigid than idiopathic, complete correction as in idiopathic foot might not be achieved. Usually, 40-45 degree of abduction and 5 degree dorsiflexion could be achieved . The recurrence rate has been higher, but the deformity tends to improve with re-casting in most cases . Moroney el al reported that after Ponseti casting, the Pirani score in feet which required surgery reduced from 5.1 to 3.7. Thus casting, even if not successful, reduced the morbidity of future surgery.
Severity in non-idiopathic clubfeet has not been classified in literature probably because of low incidence. Most often these feet are either not graded or are graded as per Dimeglio score or Pirani scores which have been described for idiopathic clubfeet. Since most non-idiopathic clubfeet are rigid and a trial of Ponseti method has been justified for most patients, we have classified non-idiopathic feet on basis of response to Ponseti casting to standardize management protocols (Table 3).
A treatment algorithm for non-idiopathic clubfeet has been outlined (Fig 1). After initial correction with Ponseti method, the main factor leading to relapse has been non-compliance of brace . The thick rigid capsule is incapable of stretching with growth and results in recurrence despite adequate bracing. . Ill-fitting brace could contribute to non-compliance. In non-idiopathic clubfeet, it is important to maintain the correction obtained which might be less than that obtained in idiopathic feet. The brace may have to be modified to the degree of correction achieved i.e. 40 – 45 degrees of abduction and 5 degrees of dorsiflexion instead of 70 degrees and 20 degrees, respectively, as in idiopathic feet. The brace modification can improve compliance . As and when flexibility improves, more bend can be added to the brace as required. Often due to concomitant hip and knee contractures, Ankle Foot Orthosis (AFO) should be considered instead of Foot Abduction Brace (FAB) for better fit and compliance. Brace might have to be modified in case of a congenital constriction band with an amputation of the other leg – by using an AFO instead of an abduction bar. A brace in the form of an AFO should be generally worn till skeletal maturity.
If there has been partial correction with Ponseti method, surgery may be required. When no visible change is seen between two consecutive casts, casting should be stopped and surgery should be considered. The procedure of choice in such cases has been controversial. It would depend on the severity of the residual deformity, the age of child and ambulatory potential. Not all cases require extensive surgery. When only residual equinus and/or forefoot varus persists, a heel cord lengthening and anterior tibialis transfer can give good results (Fig 2). With more severe residual deformities, some authors prefer extensive soft tissue releases, reserving talectomy as a salvage procedure for the most severe of all deformities. Some favour talectomy primarily stating the higher failure of soft tissue releases . Extensive soft releases i.e. posteromedial and lateral have shown good results when performed by 1-2 years of age to preserve articular congruity. If the child presents after 2 years of age or does not have ambulatory potential then a primary talectomy should be preferred to avoid recurrence and repeat surgery. Often only a talectomy is not enough to correct the deformity and should be accompanied by soft tissue release (Fig 3, 4). Cincinnati incision adequately provides the required extensive visualization for dissection medially, posteriorly and laterally .
In very severe rigid clubfeet, correction might not be achieved with Ponseti casting. Primary talectomy with extensive soft tissue releases should be considered in these children for best results.
Soft tissue releases have shown good results when done at 7-8 months of age. When soft tissue releases are done, care should be taken to do as complete of a release as possible with excision of 1-2 cm of tendon to prevent recurrence. Soft tissue releases often correct the forefoot varus, though in cases of severe rigid equinus, the equinus is often not corrected even after release of tendo Achilles and posterior capsular releases. Complete excision of the talus provides enough laxity for correction of the equinus and varus deformity. Talectomy however might not correct the forefoot deformity and additional procedure in the form of an osteotomy might be required for such severe deformities. Failure of soft tissue releases could be either due to inadequate initial correction because of tight skin and soft tissues on the medial side or due to a relapse after cast removal due to the wide medial gap created secondary to the severe deformity . However, soft tissue release is preferred in younger patients as later salvage in the form of talectomy can be done in cases of failure. When presenting at a later age, the adaptive changes in joints preferably warrant a primary bony surgery to prevent failure and recurrence.
Talectomy has shown satisfactory outcomes after short term as well as long term follow up . In younger children, however, less radical surgery may be preferred before talectomy. If a child presents late, talectomy could be performed primarily with the best results achieved when done at 1-5 years of age. Failure of talectomy may be due to poor technique, due to either partial excision or incorrect placement of the talus under the calcaneus allowing for a later posterior drift and recurrence of equinus . A failure after poorly performed talectomy, could be difficult to treat and may require a corrective osteotomy.
Triple arthrodesis is recommended if child presents after 10- 12 years of age as earlier surgery may limit the growth of that foot.
Non-idiopathic feet have a higher rate of recurrence and hence could require secondary and tertiary procedures. Recurrence within six months of previous surgery suggest incomplete correction and hence complete correction at the initial surgery should be attempted. In case of recurrence after extensive soft tissue releases, talectomy should be considered instead of revision of soft tissue releases due to scar tissue. Ilizarov external fixator can also be used primarily or in case of secondary or tertiary recurrence.
Similar to idiopathic clubfeet, the primary aim of management of non-idiopathic clubfeet should be to achieve a painless, platigrade foot with minimal number of procedures as possible. When possible, this should be achieved before walking age to prevent adaptive changes in bone. The evaluation of result should be based on the final outcome as well as the number of procedures required to achieve it.

Summary
In recent literature, Ponseti method of casting has shown promising results in non-idiopathic feet albeit in short term. Although it may not avoid surgery in these patients in long term, it definitely reduces the severity of deformity and hence the magnitude of surgery required. It should be the first line of approach in all clubfeet, irrespective of their etiology. Later, depending on the amount of correction achieved, rigidity of the feet, walking potential and age of the patient, decision related to surgical treatment should be made. Attempt to ensure complete correction should be made in the first surgery itself to avoid recurrence. This often might require extensive soft tissue release with talectomy with or without midfoot osteotomy to correct forefoot varus. Patients should be followed long-term to identify and treat recurrence and family should be strongly counselled about the importance of such follow-up visits.
