We reviewed the cases of thirty-six patients who had forty cemented total hip replacements with the Harris metal-backed acetabular component. The operations were done between 1972 and 1977, and the duration of follow-up averaged 7.6 years (range, five to 10.8 years). The average age of the patients was forty-four years (range, sixteen to sixty-two years). Aseptic loosening of the acetabular component occurred in three hips (7.5 per cent), and three more sockets were revised for other reasons. Two of the three sockets with aseptic loosening were in the fifteen patients (seventeen hips) who were forty-five years old or younger. The remaining loose cup was in one of the twenty-one patients (twenty-three hips) who were forty-six years old or older. The reduction in the rate of aseptic loosening of the socket in our series, compared with the higher rates reported in similar long-term studies in which other acetabular components were used, supports the conclusion that there is enhanced longevity of acetabular fixation when a metal-backed acetabular component is used in cemented total hip arthroplasty.
我们回顾了36例患者的病例，这些患者接受了40例使用哈里斯金属背衬髋臼组件的骨水泥型全髋关节置换术。手术于1972年至1977年间进行，平均随访时间为7.6年（范围为5至10.8年）。患者的平均年龄为44岁（范围为16至62岁）。髋臼组件出现无菌性松动的有3髋（7.5%），另有3个髋臼因其他原因进行了翻修。3例无菌性松动的髋臼中，有2例出现在15例（17髋）45岁及以下的患者中。其余松动的髋臼杯出现在21例（23髋）46岁及以上的患者中的1例。与使用其他髋臼组件的类似长期研究报告的较高松动率相比，我们系列中髋臼无菌性松动率的降低支持了以下结论：在骨水泥型全髋关节置换术中使用金属背衬髋臼组件时，髋臼固定的使用寿命会延长。
