Total shoulder prosthesis or inverted type

摘要

This total shoulder prosthesis comprises a glenoidal component, defining a substantially hemispherical convex articular surface and of which the centre of curvature is located in the glenoid cavity or in the immediate vicinity thereof, and a humeral component defining a concave articular surface adapted to cooperate with the convex articular surface of the glenoidal component. The concave humeral articular surface is defined by a metallic part of the humeral component, this avoiding having to resort to a part made of plastics material which would increase the space requirement of the prosthesis.
