Abstract

We hypothesize that cracks initiate and propagate within the initially firmly fixed cement and eventually lead to loss of implant fixation. To develop this hypothesis, mechanical failure processes were experimentally studied at the bone-cement-implant interface by cyclically loading tibial components that were fixed to cadaver tibias with polymethylmethacrylate (PMMA) using established surgical procedures. The obtained solutions give insight into possible failure processes occurring in bone cement under compression. However, the importance of these processes, relative to similar processes in other parts of the bone-cement-implant system must still be determined.
