揖Abstract铱 Objective To evaluate the complications of total hip arthroplasty (THA) with a shortening subtrochanteric osteotomy in a group of patients with Crowe type 郁 developmental dysplasia of thehip (DDH),andtorefinesurgicaltechniquestodecreasetheincidenceofthecomplications.Methods From Jun. 2002 to Aug. 2009, 35 patients (42 hips) with Crowe type 郁 DDH underwent DDH, including 24 females and 11 males, with the mean age of 渊47.4依9.61冤 years. The results and complications were evaluated retrospectively. The arthroplasty was performed in combination with a subtrochanteric shortening osteotomy and with placement of the acetabular component at the level of the anatomic hip center. Results The mean Harris hip score increased from 60.42依14.41 points preoperatively to 81.58依26.96 points at the time of final follow鄄up (P=0.0382). Eighteen of the 42 hips (42.9%) had a peri鄄operative complication. Eleven perioperative fractures happened. Two hips were followed by nonunion. Four nerve injuries and two vascular injuries occurred. One hip dislocated postoperatively. All components were well鄄fixed at the time of the last radiographic follow鄄up except one femur stem loosened. Avoidance of over or under reaming, appropriating osteotomy level and prophylactic cerclage wiring were associated with low complication rate. Conclusion Subtrochanteric osteotomy, performed in THA for osteoarthritis secondary to Crowe type 郁 DDH, is a highly complicated surgical procedure. Appropriate prosthesis selection and meticulous surgical techniques is mandatory and efficient to decrease the complication rates.
