Abstract

A rotary cutter for making the socket bed for a complete endoprosthesis is slidable on a guide rod, which rod is first inserted into a guide bore which has previously been made in the hip bone. The relative axial position of the cutter with respect to the rod indicates the depth of penetration of the cutter.
