Abstract

A modular artificial hip joint includes a head part and at least one shaft part. The shaft part, which can be driven into the bone and forms the distal region, is connected to the distal end of the head part by insertion, preferably by means of an insert cone. A first screw or tie rod, guided through an axial bore in the head part, can be screwed into the threaded bore in the shaft part. In order to guide a second screw for separating the conical insert connection between the individual components of the artificial joint, the bore in the head part is threaded and has a diameter which is greater than the diameter of the threaded bore in the shank part.
