Abstract

A hip replacement for reducing the likelihood of joint dislocation and including a femoral component having a head and an elongated neck and an acetabular cup formed with a socket to capture the head. The socket includes a formed annular liner defining a stop to engage the neck during extreme motion. The neck contact surface and annular liner cooperate to shift the resultant contact point radially outwardly from the head to minimize dislocation resulting from the moment acting upon the femoral component.
