Abstract

Many investigators consider the polymethylmethacrylate—bone interface the weakest link in the bone—cement—implant system. Push-out tests, frequently used for in vitro evaluation of the bone—cement interface, produced inconsistent results of shear strength. Therefore, a more reliable model for testing the shear failure of the interface was developed. Better understanding of intrinsic variations in bone quality and geometry of endosteal bone at the interface may yield important insight into the patterns of clinical failure of cemented total joint prostheses.
