What results in fretting wear on polished femoral stems

This paper investigates fretting wear and how it is initiated in polished, cemented total hip replacements. The mechanism is accepted to be fretting wear; this paper identifies the way in which wear is initiated and propagates and models the contact at the micro level, facilitated by a novel understanding of the surface topography. The work has enabled similar measurement and modelling techniques to be used in alternative situations, particularly at the taper-head junction in modular replacements and also in skin-device contact in alternative medical devices. The Work has input directly to a large industrial contract supported by DePuy Orthopedics.
