Abstract:
An acetabular cup, comprising an outer surface, and a bearing surface (2), defining a sperical inner surface, for receiving an articular head (8) of an artificial hip joint, wherein the bearing surface (2) is bounded in surrounding relation by a receiving edge (3) and includes an elevation (10) which ascends from the receiving edge (3) to an apex (18) positioned at a distance to a lowest point (41) of the bearing surface 2, wherein the distance exceeds a radius (12) of the spherical inner surface, wherein the receiving edge (3) descends in the direction to the lowest point (41) such that the distance is less than the radius of the inner spherical surface thereby allowing for allowing a pivot space (46) for swingably supporting a stem (48) secured to the articular head (8).
