This paper reports results from an on-going programme investigating the wear processes in cemented femoral stems and includes clinical studies and appropriate parallel laboratory tests. A number of femoral stem components removed during revision surgery have been examined and a consistent pattern of wear has been observed. Micromovement between a bone cement specimen and the metal substrate has been studied using a micro-sliding apparatus. Apparatus has been developed where axial and torsional forces can be applied to a femoral stem mounted in bone cement. The morphology and location of clinical wear damage has been successfully replicated on the femoral stems. The observed wear has been interpreted in terms of a fretting-like process between the prosthesis and the cement mantle.
