PURPOSE: The study was designed to evaluate the efficacy and safety of lesser trochanteric osteotomy for femoral shortening in total hip arthroplasty in treatment of 28 cases of CROWE IV developmental dysplasia of the hip (DDH).
METHODS: Patients underwent progressive femoral shortening at the level of lesser trochanteric to make reduction possible into the anatomical acetabulum in all hips. The results were collected and evaluated clinically and radiographically.
RESULTS: The mean follow-up period was 55.3 months. The average postoperative leg length discrepancy was eight millimetres for unilateral THA patients. A modified Merle d'Aubigné scale was improved from 9.3 preoperatively to 15.9 postoperatively. Sciatic nerve palsy was confirmed in two hips which resolved completely in six months. The Trendelenburg sign was positive in two hips at the final follow-up. No revision surgery was required by the final follow-up.
CONCLUSION: Lesser trochanteric osteotomy proved to be safe and effective in femoral shortening for treatment of CROWE IV DDH without the problem of nonunion at the site of osteotomy.
