目的评估人工全髋关节置换术（total hip arthroplasty，THA）治疗髋关节骨性强直的效果。方法自1987年8月～1998年2月，36例（38髋）行转换THA，平均术前融合时间20年1个月；平均随访8年11个月。结果Harris评分由（68．7±7．2）...目的评估人工全髋关节置换术（total hip arthroplasty，THA）治疗髋关节骨性强直的效果。方法自1987年8月～1998年2月，36例（38髋）行转换THA，平均术前融合时间20年1个月；平均随访8年11个月。结果Harris评分由（68．7±7．2）分提高到（87±6．1）分；髋关节总活动度增加180．7°±14．5°。关节疼痛缓解率为93．3％；平均肢体短缩由4．1cm降到1．6cm；人工关节存活率为86．8％。X线片示髋臼骨溶解6例，髋臼杯松动2例，股骨骨溶解4例，股骨柄松动1例。结论骨性强直的髋关节转换THA，可以缓解周围关节疼痛、增加髋关节的活动度、改善双下肢不等长和矫正髋关节畸形，提高生活质量。髋关节功能与臀中肌力量的恢复直接关联。展开更多
