Total hip arthroplasty is one of the most successful operations in all of medicine. Femoral deformities from malunion, prior osteotomy, and retained surgical implants all present unique challenges. Corrective osteotomy and hardware removal add significant morbidity to an operation that typically has a fast recovery. Short stems can be used in these cases to spare patients' increased morbidity. We present a case-based illustration and surgical technique for the use of short stems in complex primary total hip arthroplasty with femoral deformity and retained hardware. We discuss how these implants can spare significant morbidity, show radiographic examples of their use, and present short-term outcomes.
全髋关节置换术是医学领域中最成功的手术之一。骨折畸形愈合、既往截骨术以及残留手术植入物导致的股骨畸形均带来了独特的挑战。对于通常恢复较快的手术，截骨矫正和内固定取出会增加显著的发病率。在这些情况下可使用短柄假体，以降低患者增加的发病率。我们通过一个病例展示了在伴有股骨畸形和残留内固定的复杂初次全髋关节置换术中使用短柄假体的手术技术。我们讨论了这些植入物如何能够显著降低发病率，展示了其使用的影像学示例，并给出了短期疗效。
