Fig. 4From: Subtrochanteric shortening osteotomy during cementless total hip arthroplasty in young patients with severe developmental dysplasia of the hipRadiographs of a forty-two-year-old woman with unilateral Crowe type-IV DDH. (a-b) Pre-operative anteroposterior view. (c) Radiographic image at postoperative 1Â day. Total hip arthroplasty was performed combined with transverse osteotomy in left hip. (d-e) Postoperative anteroposterior view showed dislocation at 1-week follow-up, which was treated successfully through closed relocation. (f) Radiographic image after five years follow-up showed that no radiolucent lines around the femoral and acetabular components were identified. But osteolysis around the stem at the distal tip and heterotopic ossification were identified. (g-i) At eleven years follow-up, the postoperative Harris hip score was 97, and the femoral stem was judged to be stable with bone ingrowthBack to article page
