ABSTRACT:
Endoprosthetic joint particularly one permitting no appreciable adduction or abduction. There is provided an endoprosthesis for ginglymus joints comprising a first part made from a metal inert to the human body and having a substantially cylindrical head. A second part is provided of molded plastics material having a socket of substantially cylindrical shape for receiving said head. A ridge is provided around the entire perimeter of the aperture through which access to said socket is obtained, which ridge is of dimension to permit the parts to be snapped together manually but to provide substantial resistance against their becoming unsnapped. Further, the cylindrical head is only a clearance distance shorter than the corresponding dimension of the socket whereby swing motion of said head within said socket is substantially prevented.
