Total hip arthroplasty in the developmental dysplasia of the hip using transverse subtrochanteric osteotomy

Abstract

BackgroundWe assessed the results of the transverse subtrochanteric femoral shortening osteotomy technique and the cementless THA process applied to Crowe type III and IV patients with developmental dysplasia of the hips. MethodsWe retrospectively evaluated 25 patients (32 hips) between 2006 and 2014. ResultsThe mean follow-up time was 5.1 years. The mean preoperative Harris hip score was 49.5, which increased to 87.1 postoperatively. The mean preoperative leg-length discrepancy was 3.6cm; the mean postoperative discrepancy was 0.5cm. ConclusionTHA with subtrochanteric femoral shortening osteotomy technique is an effective technique for treating developmental dysplasia of the hip.
