glenoid component of shoulder prostheses, game constituent elements of said component and total shoulder prosthesis incorporating such a component.

摘要

glenoid component (2) of a shoulder prosthesis comprising a base (21), suitable to be immobilized on the glenoid (G) of a patient, and a suitable element (22) to be connected to said base and defining a surface convex articulation (S2) of which at least a portion (S2a) is generally in the form of a portion of sphere and centered on a geometric point (C2), said element (22) of a rear face (27) being provided in the leading a housing (25) receiving at least part of a portion (24) of the base centered on an axis (X21) and it said element is connected, while, in the assembled configuration of said component (2), said geometric center (C2) and said axis (X21) are offset (d) relative to one another, and whereas said element (22) defines a connection surface (S2b) extending the part (S2a) generally in the form of portion of a sphere of the articular surface (S2) to the edge (27a) of the face rear (27) at its farthest point from the geometric (C2) which is centered the surface portion (S2a) as sphere portion part.
