Abstract

An acetabular cup is supported by a pelvic bone and includes an outer surface which rests in a cavity, and a bearing surface which receives an articular body of an artificial hip joint and bounded in surrounding relation by a receiving edge. The receiving edge is provided at least at one area with an elevation which partially surrounds the articular head received by the bearing surface. The elevation is provided at a location in which the articular head is least obstructed in its freedom of movement, and has at its apex projecting furthest from the receiving edge a distance from a lowest point of the bearing surface which guides the articular head in substantially surrounding relation.
