Total shoulder prosthesis of an inverted type

摘要

A total shoulder prosthesis includes a glenoidal component a substantially hemispherical convex articular surface and of which a center of curvature is adapted, when the prosthesis is implanted, to be 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 to thereby reduce a space requirement of the prosthesis.
