On the mechanical testing of some implants and materials.
This paper discusses the proliferation of medical devices and focusses its attention on the rapid development of orthopedic implants and the attempts by federal authorities to provide standards and recommended practices. The very important aspect of implant assessment based on mechanical testing is discussed and shown to be completely lacking. Current attempts to maintain quality and safety of orthopedic implants are discussed. One test configuration for femoral components of total hip replacement is offered as an example of methods that should be established to verify a particular design in conjunction with efforts to control material composition.
