摘要

采用已建立的人工髋关节有限元模型研究半脱位时的撞击。本研究旨在通过位错扭矩和接触应力来参数化评估杯缘半径对边载荷的独立影响。本文推荐在撞击/半脱位时，髋臼衬环的唇半径为2mm，具有良好的机械性能。

Finite Element Analysis of Mechanical Effects of Lip Radii on Three Types of Acetabular Liner Rim after Prosthetic Impingement

An established finite element model of artificial hip was used to study impingement during subluxation. This investigation seeks to assess parametrically the independent effects of the cup rim radius on edge-loading by means of dislocation torque and contact stress. This article recommends 2 mm as the preferred lip radius for the acetabular liner rim with favorable mechanical performance during impingement/subluxation.
