摘要(Abstract)：

[目的]观察分析H/GI人工全髋关节置换术后髋臼假体中、远期疗效。[方法]对1992～2000年采用H/GI人工全髋关节置换术后髋臼假体置换21例(21髋)患者的临床病历和X线片进行回顾性研究。临床随访根据Harris进行评分,X线随访根据DeLee等髋臼分区进行观察。[结果]截止2010年5月10日,随访到19例(19髋),平均随访时间15年(10～18年)。19例中3髋臼杯进行了翻修,集中在术后9～12年。X线片示髋臼假体明确松动3髋、可能松动5髋,内衬磨损率为每年(0.27±0.10)mm。翻修手术中取出的假体表面的骨生长不满意。[结论]H/GI髋臼假体的中、远期疗效不满意。导致较高假体失效率原因包括内衬与金属臼杯设计不合理和过多的螺钉、螺钉孔有关的骨溶解与假体松动。
