Abstract
This prosthesis comprises a humeral or femoral component and an intermediate component. The concave surface of articulation of the humeral or femoral component is formed by a plate connected by a neck to a part of this component adapted to be anchored in the humeral or femoral medullary cavity. The intermediate component is provided with a member for retaining the humeral or femoral component in a position where the plate is in abutment against the first convex surface of the intermediate component. The retaining member defines a non-circular passage in which the neck is adapted to be displaced as a function of the movements of the humeral or femoral component with respect to the other components of the prosthesis. The retaining member defines with the first convex surface of articulation of the intermediate component a volume for receiving a part of the plate projecting radially with respect to the neck.
