Taperosis/trunnionosis is a scientific term for describing tribocorrosion (fretting corrosion) at the head-neck taper junction of hip implants where two contacting surfaces are undergone oscillatory micromotions while being exposed to the body fluid. Detached ions and emitted debris, as a result of taperosis, migrate to the surrounding tissues and can cause inflammation, infection, and aseptic loosening with an ultimate possibility of implant failure. Improving the tribocorrosion performance of the head-neck junction in the light of minimising the surface damage and debris requires a better understanding of taperosis. Given its complexity associated with both the mechanical and electrochemical aspects, computational methods such as the finite element method have been recently employed for analysing fretting wear and corrosion in the taper junction. To date, there have been more efforts on the fretting wear simulation when compared with corrosion. This is because of the mechanical nature of fretting wear which is probably more straightforward for modelling. However, as a recent research advancement, corrosion has been a focus to be implemented in the finite element modelling of taper junctions. This paper aims to review finite element studies related to taperosis in the head-neck junction to provide a detailed understanding of the design parameters and their role in this failure mechanism. It also reviews and discusses the methodologies developed for simulating this complex process in the taper junction along with the simplifications, assumptions and findings reported in these studies. The current needs and future research opportunities and directions in this field are then identified and presented.

结核病/耳蜗病是一个科学术语，用于描述髋关节植入物的头颈部锥度连接处的摩擦腐蚀（微动腐蚀），其中两个接触面在暴露于体液的同时经历振荡微运动。分离出的离子和散落的碎屑，是由于塔形菌病而迁移到周围组织的，可引起炎症，感染和无菌性松动，最终有可能导致植入失败。根据最大程度地减少表面损伤和碎屑来改善头颈连接处的摩擦腐蚀性能，需要更好地了解锥度。鉴于其复杂性与机械和电化学方面都相关，最近已采用诸如有限元法之类的计算方法来分析锥度结中的微动磨损和腐蚀。迄今为止，与腐蚀相比，在微动磨损模拟方面已有更多的努力。这是由于微动磨损的机械特性，对于建模而言可能更简单。然而，随着最近的研究进展，腐蚀已经成为锥形结的有限元建模中的重点。本文旨在回顾与头颈部交界处的锥度有关的有限元研究，以提供对设计参数及其在这种失效机制中的作用的详细了解。它还回顾并讨论了为在锥度连接处模拟此复杂过程而开发的方法，以及在这些研究中报告的简化，假设和发现。
