The study utilized the geometric element analysis method to investigate the effect of three variables (head diameter, d; head material; and neck material) on the y-direction displacement, due to fretting (delta), in a model of the head-neck connection in a modular version of the femoral component of a hip implant, subjected to a resultant hip joint force only. It was found that while d and neck material exerted a strong effect on delta, the head material had practically no such effect. The implications of this finding for design and materials selection issues for this connection are discussed.
该研究采用几何元素分析方法，在仅承受髋关节合力的髋关节置换股骨部件模块化版本的头颈连接模型中，研究三个变量（头部直径d、头部材料和颈部材料）对微动引起的y方向位移（δ）的影响。研究发现，虽然d和颈部材料对δ有很大影响，但头部材料实际上没有这种影响。讨论了这一发现对该连接的设计和材料选择问题的影响。
