The invention concerns a shoulder prosthesis assembly comprising a meta-glenoid element (7) formed by a plate (13) provided with a central tubular block (14) an anchoring members in the glenoid cavity (3), and a glenoid sphere (9) designed to top the metaglenoid element and provided with an axial screw (35) screwed into said pin; the glenoid sphere has an articulated surface (11) designed to co-operate with a cup of an associated humeral prosthesis (2); said assembly comprises means (16, 45, 46; 51, 50, 49) guiding the glenoid sphere adapted to facilitate its being fixed on the meta-glenoid element; said means comprise a pin (46) adapted to be slotted into the tubular block (14) and into an axial passage of the screw (35); the glenoid sphere (9) is thus guided by being slid on the pin (46) until the screw
A shoulder prosthesis assembly, comprising a metaglenoid element (7) formed by a plate (13) provided with a central tubular bushing (14) together with members (25, 27) for anchoring it in the glenoid cavity (3), and a glenoid sphere (9) adapted to be fitted over the metaglenoid element and provided with an axial screw (35) capable of being screwed into said bushing, the glenoid sphere presenting a joint surface (11) for co-operating with a cup (12) of an associated humeral prosthesis (2), the assembly being characterized in that it includes means (16, 45, 46;
