The purpose of this study was to evaluate our experience with treatment of clubfoot in myelomeningocele. We evaluated 45 children with clubfoot surgically treated at a mean age of 36 months. We evaluated each patient's medical record and performed a physical examination. Based on the clinical criteria by de Carvalho Neto, we obtained 61% good results, 26% fair results and 13% poor results. Neither age at surgery nor neurosegmental level have any statistical influence on final outcome. We find that a radical posteromedial release without internal fixation is a satisfactory option for clubfoot with myelodysplasia.

Osteogenesis imperfecta is one of the most common groups of inherited disorders of connective tissue. Hyperplastic callus formation in patients with osteogenesis imperfecta after fracture or surgery is a rare occurrence that has often been misdiagnosed as osteosarcoma. Previous series reported that hyperplastic callus formation is more often present in osteogenesis imperfecta male patients, with white sclerae, and a negative family history of the disorder. This is the first time that this complication has been presented in three female siblings, with a positive family history of osteogenesis imperfecta type IV. An association between osteogenesis imperfecta type IV and hyperplastic callus formation is unclear. This association might, however, be a separate, specific subtype of osteogenesis imperfecta, with an unknown inheritance pattern.
