The aim of this article is to propose a diagnostic and therapeutic algorithm for the acetabular periprosthetic fractures.
This article explores the current literature on the epidemiology, causes and classification of periprosthetic acetabular fractures. Integrating data with the experience of the authors, it offers a guide to diagnosis and possible therapeutic strategies.
Intra-operative fractures can occur during rasping, reaming or implant impaction, and they must be treated immediately if the component(s) is (are) unstable. Post-operative fractures can be due to major trauma (acute fractures) or minor forces in bone osteolysis; it is possible to plan reconstruction and fixation according to fracture characteristics. Treatment choice depends upon fracture site and implant stability.
Periprosthetic acetabular fractures are uncommon complications that can occur intra-operatively or post-operatively, and a reconstructive surgeon must be able to manage the procedure. Accurate planning and reconstruction implant are necessary to achieve good cup stability.
本文旨在提出一种髋臼假体周围骨折的诊断和治疗方案。
本文探讨了有关假体周围髋臼骨折的流行病学、病因及分类的当前文献。结合作者的经验和数据，提供了诊断指南及可能的治疗策略。
术中骨折可发生于锉削、扩髓或植入物撞击过程中，若假体部件不稳定则必须立即处理。术后骨折可能由重大创伤（急性骨折）或骨溶解中的微小外力所致；可根据骨折特征规划重建和固定方案。治疗选择取决于骨折部位及植入物稳定性。
假体周围髋臼骨折是术中或术后可能出现的罕见并发症，重建外科医生必须能够处理该手术。精确的规划和重建植入物对于实现髋臼杯的良好稳定性是必要的。
