摘要
目的探讨成人严重发育性髋关节发育不良(DDH)进行人工全髋关节置换术(THA)的方法及治疗效果。方法18例CroweⅣ级DDH的患者行THA,术中在软组织松解延长的基础上,重建髋关节旋转中心在真臼位置及髋关节外展功能。术后评估髋关节功能。结果术后平均随访21个月,髋关节Harris评分平均为90分,患肢长度平均延长2.6cm,有1例出现坐骨神经牵拉症状,短期未出现假体失败现象。结论通过松解延长、重建关节功能、选择合适的假体,并注重对神经血管的保护,成人严重DDH可以通过THA获得满意的治疗效果。
Objective To discuss the methods and clinical results of total hip arthroplasty for the adults with developmental dysplasia of the hip （ DDH ）. Methods Eeighteen patients with unilateral Crowe type-IV dislocation underwent total hip replacement. In the operation procedure, the acetabular rotation center and abductor function were reconstructed on the basis of soft tissue release. The evaluation after surgery included the leg-length and Harris scores. Results The average follow-up period was 21 months and the average postoperative Harris hip score was 90 points. The average leg-lengthening was 2.6 cm. One patients appeared sciatic nerve palsy. No implants failure was found in short time follow up. Conclusions Total hip arthroplasty could effectively treat server DDH of adult by the methods of tissue release, reconstruction of acetabular, proper selection of prosthetic and protection nerve.
