Implant modularity has recently come under increasing scrutiny due to concerns regarding wear, corrosion and potential adverse reactions to metal debris. This review outlines the evolution and development of the femoral stem trunnion and relates this to contemporary issues now encountered.Despite different manufacturers producing what appear to be similar trunnion designs, there is still a lack of standardisation, with small but significant design variations. Wear and corrosion is certainly not a new phenomenon, but recent changes in design and the use of larger metal head sizes has potentially made the problem more prevalent. These issues along with steps to avoid these problems are discussed.
由于对磨损、腐蚀以及金属碎屑潜在不良反应的担忧，植入物模块化近来受到越来越多的审视。本综述概述了股骨干耳轴的演变与发展，并将其与当前遇到的问题联系起来。尽管不同制造商生产的耳轴设计看似相似，但仍缺乏标准化，存在虽小却显著的设计差异。磨损和腐蚀当然不是新现象，但近期设计的变化以及更大尺寸金属股骨头的使用可能使这个问题更加普遍。本文将讨论这些问题以及避免这些问题的措施。
