PEMBERTON OSTEOTOMY FOR RESIDUAL ACETABULAR DYSPLASIA IN CHILDREN WHOHAVE CONGENITAL DISLOCATION OF THE HIP

We reviewed the results for fifty-two hips in forty-two patients who h ad had a Pemberton pericapsular osteotomy between 1968 and 1984 as tre atment for residual acetabular dysplasia of the hip. The average age o f the patients at the time of the osteotomy was four years. The averag e duration of follow-up was ten years. At the time of the most recent follow-up, forty-two of the fifty-two hips had a rating of Severin cla ss IA, an essentially normally developed hip. The results of the Pembe rton osteotomy were unpredictable if there had been necrosis of the fe moral head (without infection) preoperatively. We believe that the Pem berton osteotomy is a safe, effective procedure for the treatment of a cetabular dysplasia in patients who have congenital dislocation of the hip.
