Abstract

A femoral stem surgical instrument system includes a handle component and an impact component, either one of which is selectively coupled with a femoral stem through a recess in the femoral stem, the recess providing separate facilities for the appropriate coupling of either of the components with the femoral stem, with each of the separate facilities being protected against damage when the other of the facilities is in use.
