title: Management of ischemic deformity after the treatment of developmental dysplasia of the hip.
abstract: Long-term results of 69 hip operations for deformities due to avascular necrosis following the conservative treatment of the hip dysplasia were evaluated. The authors' technique of intertrochanteric valgus osteotomy allows for simultaneously handling of varus deformity and shortening of the femoral neck, fusion of the greater trochanter, and correction of increased femoral anteversion, if necessary. This type of surgery was used in children with Buchholz-Ogden type III deformity starting from 3 years of age until adolescence. Patients were followed for an average of 19.3 years. Eighty-seven percent had no marked limitation in range of motion and 57% were free of complaints. Trendelenburg gait was present in only six patients. Radiographs of all patients showed improvement of coxometric values. Acetabular dysplasia was handled in 29 patients with a subsequent shelf arthroplasty. Total hip arthroplasty for hip degeneration was not indicated for any of the patients to date.
