ABSTRACT:
A hipjoint socket has an outer cup and an inner cup disposed within and secured to the outer cup. The inner cup has a hemispherical bearing surface which is concentric with an axis and terminates at the end face, which is perpendicular to the axis. An open groove formed in the end face is concentric with the axis. A closed ring has axially relatively longer and shorter portions and a cylindrical guiding surface having a diameter about equal to a diameter of the hemispherical guiding surface. The ring includes tongues engaging the groove and thereby securing the ring to the inner cup when the ring abuts the end face. The tongues are able to slide along the groove and position the cylindrical guiding surface concentric with the axis and substantially contiguous with an end of the hemispherical bearing surface at the end face. The ring can be rotated relative to the inner cup upon the implantation of the socket to position the relatively longer ring portion on the socket where it prevents luxation of a femur head cooperating with the socket.
