[摘要] 目的探讨微创全人工关节置换治疗髋关节强直的疗效。方法 2006年6月至2009年7月,13例(21髋)髋关节强直患者在微创入路下行人工全髋关节置换,年龄20~66岁(平均46岁),病因为:强直性脊柱炎5例(10髋),类风湿性关节炎4例(6髋),股骨头无菌性坏死继发严重骨性关节炎2例(3髋),髋关节感染后遗强直畸形2例(2髋)。患者患髋均无活动度,均选用生物型人工关节,13髋为解剖头金属对金属界面,8髋为陶瓷对陶瓷界面。结果手术顺利,手术时间(80±12)min(最短60min),术中出血量(380±156)ml。所有患者术后均获得随访,随访时间12~48个月,术后X线评价人工关节位置良好,术中无骨折,术后无假体松动、关节脱位、感染及深静脉栓塞等并发症。Harris评分:术前(±)分,术后至最后1次随访(±)分,差异有统计学意义(P<)。结论对于外展肌功能存在的髋关节强直患者行微创人工关节置换,能有效改善髋关节功能,提高患者生活质量,创伤小,恢复快。

[Abstract]Objective To discuss the techniques and the effect of minimally invasive on total hip arthroplasty for stiff hip. Methods From June 2006 to July 2009,13 patients(21hips) with stiff hip received in total hip arthroplasty with minimally invasive techniques, and their age between 20 years and 66 years(mean, 46 years),with contraction function of abducent cause of stiffness include that ten hips(5 patients) are from spinal akylosis;six hips(4 patients) are from rheumatoid arthritis;three hips(2 patients) are secondary from AVN of the femoral head,and two hip
