We report the results of our continued review of 11 total hip arthroplasties using 22.225 mm alumina ceramic femoral heads on a Charnley flanged stem, articulating with chemically cross-linked polyethylene. There was an initial bedding-in of up to 0.41 mm at the articular surface in the first two years. This had not progressed further, at a minimum follow-up of 15 years. Radiographically no femoral or acetabular component showed loosening or osteolysis.
我们报告了对11例全髋关节置换术的持续评估结果，这些手术使用的是22.225毫米氧化铝陶瓷股骨头，安装在Charnley带凸缘柄上，与化学交联聚乙烯进行关节连接。在最初的两年中，关节表面的初始磨合达0.41毫米。在至少15年的随访中，这种情况没有进一步发展。影像学检查显示，股骨或髋臼部件均未出现松动或骨溶解。
