Abstract

We report a case of extended osteolysis, requiring a third revision of the left hip in an 85-year-old man 46 years after index operation. Major polyethylene (PE) wear occurred due to a missmatched combination of a bipolar Hastings head with a PE liner and head damage of the originally maintained stem. This case demonstrates that bipolar heads should not be used with PE cup liners since the respective bearing diameters cannot be guaranteed to match due to missing specifications. Furthermore, putting a Hastings head on an already damaged head of the stem should be omitted and rather the stem should initially be revised.

摘要

我们报告了一例85岁男性在初次手术46年后出现广泛骨质溶解，需要对左髋关节进行第三次翻修的病例。主要的聚乙烯（PE）磨损是由于双极哈斯汀斯股骨头与PE内衬不匹配组合以及原保留柄的头部损伤所致。该病例表明，双极股骨头不应与PE杯内衬一起使用，因为由于缺少规格，无法保证各自的轴承直径匹配。此外，不应将哈斯汀斯股骨头安装在已损坏的柄头上，而应首先对柄进行翻修。
