Disposable provisional instrument component for evaluating the fit of an orthopaedic implant

摘要

A provisional instrument component 1 for evaluating the fit of a corresponding orthopaedic implant. The component 1 is intended and designed to be a disposable, single use provisional instrument component. The provisional instrument component 1 is made of a material which can be sterilized by gamma irradiation, but which provides a visible indicator, such as visible deformation 10, upon resterilization by exposure to a heated environment, thereby discouraging or preventing re-use of the component 1.
