Abstract
In this study, a hemi-pelvis of composite sawbone was implanted with a Charnley cup using a conventional bone cement and the acetabular replacement was tested under constant amplitude cyclic loads, simulating the maximum hip contact force during normal walking. The damage development in the reconstruction was detected and monitored using CT scanning at regular test intervals, verified by microscopy post testing. Three identical experimental results showed that extensive debonding at the bone–cement interface occurred around the dome region after 20 million cycles.
