Abstract
We reviewed the results of operative treatment in 20 patients (23 hips) with congenital dislocation of the hip. Patients age at surgery raged from 11 months to 4 years. Average follow-up period was 8.1 years. The surgical procedure included open reduction, derotation and varus femoral osteotomy and femoral shortening. Salter pelvic osteotomy was later added in 9 hips.The postoperative clinical results were excellent or good in all whole patients. Radiographic evaluation using the Severin grading system revealed excellent or good results in 13 of 17 hips (76%).We found no evidence of avascular necrosis of the femoral head. These results show that decompression by femoral shortening is important to prevent avascular necrosis of the femoral head.
