Total hip arthroplasty in the treatment of ankylosing spondilitis with hip ankylosis

目的探讨全髋关节置换术治疗强直性脊柱炎髋关节强直的临床效果。方法对11例强直性脊柱炎髋关节强直患者（22髋）进行全髋关节置换术,术后行踝关节及足趾屈伸等功能锻练。结果术后髋关节活动度明显改善,屈曲畸形基本矫正。11例均获随访,时间2-6年。未出现关节脱位和假体松动。Harris评分由术前9-58（36±9.8）分提高到末次随访时64-94（81.2±10.6）分,优13髋,良6髋,中3髋。结论全髋关节置换术治疗强直性脊柱炎髋关节强直能显著改善髋关节功能,矫正髋关节畸形,近期疗效满意。

Objective To study the curative effect of total hip arthroplasty（THA）in the treatment of ankylosing spondilitis with hip ankylosis.Methods 11 cases of ankylosing spondilitis with hip ankylosis（22 hips） were performed by THA and ankle and foot exercises were done after operation.Results Function of hip joint improved evidently after operation,and flexion deformity disappeared basically.After following up for 2～6 years,there was no sign of loosening,dislocation.The clinical results were evaluated by the Harris hip scoring system.Harris hip score improved from 9~58（36±9.8） points preoperatively to 64~94（81.2±10.6） points at the final postoperatively evaluation.13 hips were excellent effect,6 good and 3 fair.Conclusions THA can greatly improve the function and rectify deformity of hip joint of patients with ankylosing spondilitis with hip ankylosis.The short term curative effect is satisfactory.
