A critical component in the evaluation of a patient with a periprosthetic hip fracture is determination of stem stability. Failure to critically evaluate preoperative radiographs and subsequently intraoperative stem position may result in an incorrect treatment algorithm and early catastrophic failure of the implant construct. In 2018, this is becoming a larger issue as demand for revision total hip arthroplasty increases. Several factors contribute to the type of implant used in these fractures and depend on age, activity level, comorbidities, and available bone stock. The purpose of this article is to review the evaluation of periprosthetic hip fractures around a loose stem and provide tips and tricks for their management to allow for a successful, long-lasting outcome.
评估人工髋关节假体周围骨折患者的一个关键组成部分是确定假体柄的稳定性。如果不能仔细评估术前 X 线片，随后术中假体柄位置不当，可能导致治疗方案错误，并导致假体早期灾难性失效。2018 年，随着对翻修全髋关节置换术需求的增加，这一问题变得更加突出。影响这些骨折中使用何种假体的因素有很多，取决于年龄、活动水平、合并症和可用的骨量。本文的目的是回顾评估松动假体柄周围的髋关节假体周围骨折，并提供其处理技巧，以获得成功、持久的效果。
