摘要(Abstract)：

[目的]探讨全髋关节表面置换术治疗成人髋关节发育不良继发骨关节炎的疗效、安全性和有效性。[方法]2005年5~6月,对12例成人髋关节发育不良继发骨关节炎患者13个髋关节进行全髋关节表面置换术。男性4例,女性8例;年龄30~59岁,平均47岁,所有患者均为半脱位型。髋臼侧采用真臼位置重建,为非骨水泥固定,股骨头假体采用骨水泥固定。[结果]手术时间平均110 m in,术中失血平均387 m l,术后引流量平均200 m l,肢体延长平均9 mm(术前短缩平均14 mm)。所有患者切口均一期愈合,无感染、股骨颈骨折、脱位、松动、神经血管损伤等并发症。全部随访12~13个月,临床效果满意,平均髋关节活动度屈曲由106.7°增加到120°,外展由25.8°增加到46.4°,外旋由20.8°增加到45°,内旋由3.3°增加到28.6°,Harris评分由术前的平均42分增加到术后的平均96分。X线片显示关节假体位置正常,人工髋臼平均外展角为39°,股骨头中心柄与股骨干夹角平均141°,髋关节旋转中心位置平均下移9 mm,内移11.5 mm。宿主骨对臼杯的平均覆盖率为89.5%,宿主骨与假体之间未见透亮线。[结论]全髋关节表面置换术治疗半脱位型的成人髋关节发育不良继发骨关节炎患者具有良好的近期疗效和应用前景,其远期疗效及其他类型髋关节发育不良患者的应用还需进一步研究。
