Abstract

A modular hip joint prosthesis is assembled from a head section having a connection for the ball of the joint and from a shaft section. The shaft section is joined by a insert connection to the head section, and provision is made for fixing the insert connection. The insert connection is situated in the region of Shenton's arc. The respective contours, in longitudinal section, of the head and shaft sections in the region of the connection merge smoothly, without any substantial change in direction, irrespective of the relative mutual alignments of the sections at any given time, with the exception of a gap in the immediate vicinity of the connection.
