The Harris-Galante I modular acetabular components (Zimmer, Warsaw, Ind) were most widely used in the 1980s in primary and revision total hip arthroplasty. We assessed 76 primary total hip arthroplasties performed using Harris-Galante I modular acetabular components. Dissociation of the polyethylene liner occurred in 5 patients and required revision surgery. None of the 76 hips had fractures of the metal locking tines on the metal shell. Liner dissociation was attributed to fatigue fracture of the polyethylene, a result of a gap between the liner and the metal shell. The thin polyethylene liner rim aggravated failure. The revision technique was to cement the polyethylene liner into the well-fixed Harris-Galante metal shell. The average follow-up observation period after revision surgery was 6.4 years; and there was no recurrence of dissociation, which supports the use of our revision technique.
哈里斯-加兰特I型模块化髋臼组件（捷迈公司，印第安纳州华沙）在20世纪80年代的初次和翻修全髋关节置换术中使用最为广泛。我们评估了76例使用哈里斯-加兰特I型模块化髋臼组件进行的初次全髋关节置换术。5例患者出现聚乙烯内衬分离，需要进行翻修手术。76个髋关节中没有一个金属外壳上的金属锁定齿发生骨折。内衬分离归因于聚乙烯的疲劳骨折，这是内衬与金属外壳之间间隙导致的结果。薄的聚乙烯内衬边缘加剧了失效。翻修技术是将聚乙烯内衬用骨水泥固定到固定良好的哈里斯-加兰特金属外壳中。翻修手术后的平均随访观察期为6.4年；且没有分离复发的情况，这支持了我们翻修技术的应用。
