Fractures of well-ingrown femoral components are a rare and often challenging complication after revision total hip arthroplasty. Prior series have documented catastrophic failure at the modular junction of revision femoral components. However, to the authors' knowledge, there has been only 1 report of a mid-stem fracture of a modular tapered revision stem. The present article reports 2 cases of fatigue fractures (14 months and 10 years after implantation) of a tapered modular revision stem. It presents the results of the fracture surface analysis, discusses the etiology of failure, and presents the authors' recommendations on how to best avoid this complication.
在翻修全髋关节置换术后，骨长入良好的股骨假体骨折是一种罕见且常具有挑战性的并发症。既往系列报道记录了翻修股骨假体在模块化连接处的灾难性失败。然而，据作者所知，仅有1例关于模块化锥形翻修柄中段骨折的报告。本文报道了2例锥形模块化翻修柄疲劳骨折病例（植入后14个月和10年）。文章展示了骨折表面分析结果，讨论了失败原因，并提出了作者关于如何最佳避免这一并发症的建议。
