Treatment of multiple pterygium syndrome.

Multiple pterygium syndrome is a rare, inherited disorder manifested by growth retardation, facial or genital anomalies, and widespread musculoskeletal deformities. Pterygia are the predominant hallmark of the syndrome. Five children with multiple pterygium syndrome were treated from 1978 to 1987. Treatment involved both upper and lower pterygia and contractures. The results of treatment and modalities used are discussed and a protocol suggested.

Hyperplastic callus formation in osteogenesis imperfecta following intramedullary rodding.

Hyperplastic callus formation has been reported in patients with osteogenesis imperfecta following fractures but not following intramedullary rodding. The present case is that of a child who developed massive hyperplastic callus following osteotomy and intramedullary rodding of all lower extremity bones. Noted complications of intramedullary rodding include refracture, delayed union, nonunion, and pin migration, and it is our belief that hyperplastic callus formation should be considered another potential complication.

The Grice extraarticular subtalar arthrodesis: a clinical review.

One hundred forty-nine Grice procedures performed between 1955 and 1982 were reviewed. The valgus deformities were secondary to poliomyelitis, cerebral palsy, myelodysplasia, flexible flatfoot, clubfoot, congenital vertical talus, and other neuromuscular diseases. Review consisted of radiographic and clinical follow-up. Overall evaluation revealed 46% unsatisfactory results because of both graft failure and residual clinical deformity. Previous unrecognized ankle valgus and instability prejudiced the results in the myelodysplasia and flexible flatfoot. Recommendations include consideration of the Grice procedure in poliomyelitis and cerebral palsy coupled with appropriate tendon balancing, but not in myelodysplasia or flexible flatfoot in the presence of often unrecognized ankle valgus.

Clinical experience with the reciprocal gait orthosis in myelodysplasia.

Ambulation has always been difficult for patients with myelodysplasia; however, introduction of the reciprocal gait orthosis seemingly offered increased potential as an ambulatory aid. Review of 41 patients with myelodysplasia treated with the reciprocal gait orthosis revealed that 78% reached community or household ambulator status, a marked improvement over previous results with traditional hip-knee-ankle-foot orthoses.

Bilateral congenital dislocation of the patella.

A 19-month-old nonambulatory child with knee flexion contractures was found to have dislocated patellae. Only three previous cases of bilateral congenital dislocated patellea have been reported. Surgical treatment rationale and technique are reviewed.

Criteria for selective fusion in idiopathic scoliosis using Cotrel-Dubousset instrumentation.

Spinal decompensation after Cotrel-Dubousset (C-D) instrumentation in the King type II curve pattern has become a recognized complication secondary to progression of the unfused lumbar curve. Twenty-three patients with type II curves who underwent selective thoracic fusion according to the guidelines established by King et al. were reviewed. Mean follow-up was 19.5 months. Lumbar curves greater than 45 degrees associated with a low flexibility index were significantly more likely to develop postoperative progression of the uninstrumented lumbar curve with resultant spinal decompensation, suggesting that in these curves the King criteria for selective thoracic fusion may not be appropriate.

The Bridle procedure: a new treatment for equinus and equinovarus deformities in children.

The Bridle procedure is a tritendon anastomosis between the posterior tibialis, anterior tibialis, and peroneus longus, combined with an Achilles tendon lengthening for treating equinus and equinovarus deformities. The technique avoids problems of tendon attachment to bone and tendon placement for balance. One hundred seven procedures were performed on patients with cerebral palsy with 74% excellent and good results overall. The average follow-up was 5 years 9 months. The procedure was also performed with mixed results, on smaller groups of patients with other neuromuscular diseases.
