Abstract
Abstract This invention relates to a socket for a hip joint prosthesis which allows a great freedom of motion over at least 60*, with at least two externally fixed pins, wherein the rim of the socket is offset over at least a section relative to the plane of the rim to form a notch parallel to the rim. The socket has also means for its exact and rapid positioning in the acetabulum.
