Abstract

We reviewed 1039 revision total hip replacements where an angle-bore acetabular component was used. After a mean follow-up of nine years (0 to 20.6), the incidence of revision for dislocation was 2.1% (22 revisions), a success rate of 97.9%. In 974 revisions, where the indication was other than dislocation, the success rate was 98.5%. Of the 65 revisions for dislocation, 58 (89.2%) were successful after the first revision and a further five after the second revision, an overall success of 96.9%. Two patients elected to have their implants removed. Dislocation after revision of failed total hip replacement is a complex issue. There is often no single cause and no simple solution. The angle-bore acetabular component, in combination with a 22.225-mm diameter femoral head, offers a high level of success.

摘要

我们回顾了1039例使用角向钻孔髋臼组件的全髋关节翻修术。平均随访9年（0至20.6年）后，脱位翻修的发生率为2.1%（22例翻修），成功率为97.9%。在974例因非脱位原因进行的翻修中，成功率为98.5%。在65例脱位翻修中，58例（89.2%）在首次翻修后成功，另有5例在第二次翻修后成功，总体成功率为96.9%。两名患者选择取出植入物。失败的全髋关节置换翻修术后的脱位是一个复杂的问题。通常没有单一原因，也没有简单的解决办法。角向钻孔髋臼组件与直径22.225毫米的股骨头相结合，成功率较高。
