The stem-cement interface experiences fretting wear in vivo due to low-amplitude oscillatory micromotion under physiological loading, as a consequence it is considered to play an important part in the overall wear of cemented total hip replacement. Despite its potential significance, in-vitro simulation to reproduce fretting wear has seldom been attempted and even then with only limited success. In the present study, fretting wear was successfully reproduced at the stem-cement interface through an in-vitro wear simulation, which was performed in part with reference to ISO 7206-4: 2002. The wear locations compared well with the results of retrieval studies. There was no evidence of bone cement transfer films on the stem surface and no fatigue cracks in the cement mantle. The cement surface was severely damaged in those areas in contact with the fretting zones on the stem surface, with retention of cement debris in the micropores. Furthermore, it was suggested that these micropores contributed to initiation and propagation of fretting wear. This study gave scope for further comparative study of the influence of stem geometry, stem surface finish, and bone cement brand on generation of fretting wear.

SummaryIn two dogs with periprosthetic infection after total hip replacement, the femoral cement mantle was retrieved by proximal extraction without an invasive osteotomy or cortical fenestration. En-bloc femoral cement removal was performed by injection of polymethylmethacrylate cement into the central mantle void left after stem removal, and by threading a positive profile pin into the newly injected cement. Once the PMMA had polymerized, the pin was withdrawn with the entire mantle attached. This technique should be considered in patients with circumferential deterioration of the femoral bone-cement interface in which the diameter of the femoral isthmus would not obstruct withdrawal of the cement mantle.
