Provisional orthopedic implant with removable guide

摘要

A provisional orthopedic prosthetic component and a removable guide element. The provisional component may be mounted to a bone prior to fully preparing the bone for receiving a corresponding permanent prosthetic component to preliminarily assess the fit of the permanent prosthetic component. The guide element is then attached to the provisional component. The guide element is engaged with a surgical tool to position the tool for preparing the bone for the permanent prosthetic component. In an alternative embodiment, the provisional component is an assembly of first and second provisional components. After mounting the provisional assembly on a partially prepared bone, the second provisional component is interchanged with a guide element which is mounted on the first provisional component. The guide element is used to position a surgical tool relative to the first provisional component. Both embodiments may be mounted on a distal femur and define a single-condylar shaped projection.
