Abstract

Aim: We aimed to assess outcomes of a 12-year longitudinal observational study of developmental dysplasia of the hip (DDH) requiring surgical intervention.

Method: We conducted a prospective study from 2004 to 2015 of all cases of DDH undergoing surgical intervention. In addition to clinical examination, Tönnis acetabular index (AI) method and International Hip Dysplasia Institute (IHDI) grading used.  Avascular necrosis of the femoral head (AVN) was assessed by the Kalamchi method.

Results & Discussion: There were 81 hips in 72 patients (12 male, 60 female).  Mean age of the first operative procedure was 16.4 months (95% CI, 13.66 to 19.14). Mean follow up was 47.6 months (95% CI, 41.8 to 53.4). 31 children underwent closed reductions, 48 required open reduction; 17 femoral and 39 pelvic osteotomies were performed during the course of the study. Overall, post-surgery 96.3 % were noted to have an acceptable AI (< 2 SD of the mean).  Five hips were considered to have poor results due to residual subluxation/ dislocation (6.2%).  Evidence of avascular necrosis was present in 16 of the 81 hips (19.8%).

Higher grades of hip pathology were generally associated with a later age of diagnosis and likely to require more extensive surgical interventions.

Conclusion: Operative intervention for DDH results in acceptable clinical and radiographic outcomes in the vast majority of children.

Abstract

Background: The common peroneal nerve (CPN) or external popliteal nerve is the most frequently involved nerve in entrapment syndromes in the lower extremities. Its proximity to the head of the fibula makes it particularly susceptible to damage by different injury mechanisms. Osteochondromas arising from the proximal fibula are a rare cause of common peroneal nerve injury.
Methods: We report a case of a 13-year-old Caucasian male patient referred to our hospital with drop foot and palpable mass in the head of the right fibula. Physical examination revealed a severe paresis, grade 2 objectified by the scale of the Medical Research Council (MRC) in the extensor hallucislongus, extensor digitorumlongus and tibialis anterior muscles and hypoesthesia in the dorsal surface of foot and portions of the anterior, lower-lateral leg. In magnetic resonance imaging (MRI) a tumor in the head of the fibula compressing the CPN is observed. Electromyographic studies confirmed the presence of severe partial axonotmesis of the right peroneal nerve.
The patient underwent surgery for decompression of the peroneal nerve and resection of the proximal fibula osteocartilaginousexostosis. The histopathological analysis confirmed the diagnosis of osteochondroma.
Results: At the 12-month postoperative follow-up the patient recovered sensitivity and presented, according to the MRC scale, muscle strength of 4 out of 5 in thepreviouslynamed muscles, being able to walk without orthotic devices. In the electromyography, subacuteaxonotmesis with important signs of active reinnervation observed
Conclusions : Osteochondroma in the head of the fibula is a rare cause of CPN injury, that can go easily unnoticed and has to be considered in the differential diagnosis of the drop foot in pediatric ages. Diagnosis and treatment should not be delayed to get a good neurological recovery because, otherwise, it could be irreversible.
