Objective This study was performed to document the clinical and radiographic results of consecutive patients with Crowe IV developmental dysplasia of the hip (DDH) treated by cementless total hip arthroplasty (THA) using an S-ROM femoral component with shortening derotational subtrochanteric osteotomy. Methods Twenty-three hips of 21 patients with Crowe IV DDH were treated by cementless THA combined with shortening derotational subtrochanteric osteotomy from January 2005 to January 2011. The mean preoperative modified Harris hip score (mHHS) and University of California, Los Angeles (UCLA) activity score were 40.7 and 4.2, respectively. Results The mean follow-up was 105 months. The mean mHHS and UCLA score improved to 87.0 and 9.1, respectively, at the latest follow-up. Nine of the 23 hips had a negative Trendelenburg sign. One of the 23 hips was outside the Lewinnek acetabular cup inclination safe range, and 3 of the 23 hips were outside the Lewinnek acetabular cup anteversion safe range. The probability of prosthesis survival was 100% at 5 years and 91.3% at 10 years. Conclusion Patients with Crowe IV DDH can be treated by cementless THA combined with shortening derotational subtrochanteric osteotomy. This method can greatly improve hip joint function and relieve pain without significant complications.
