Abstract: This shoulder prosthesis, comprising a glenoid element (6) intended to be attached to the scapula. According to the invention, this glenoid element (6) comprises a distal anchoring tail (20) and a proximal flange (21), the distal anchoring tail (20) having a substantially “I-shaped” cross-section, i.e. with a central core and two side walls substantially perpendicular to this central core, and with a helicoidally twisted shape, and the proximal flange (21) being perforated with at least one hole (30); and the prosthesis comprises at least one screw (5) intended to be engaged into the hole (30) of said flange (21) and inserted into the bone.

Abstract: The subject of the invention is a shoulder prosthesis (5, 32) comprising a humerus rod (9, 39) intended to be introduced into the medullary cavity of a fractured humerus (2), and a roughly hemispherical head (12) which can be secured to the humerus rod and is designed to become lodged in a glene of the shoulder, characterized in that the humerus head (12) can be fixed to the humerus rod in any radial plane with respect to the axis of the humerus rod (9, 39) after the rod (9, 39) has been fixed into the humerus and the shoulder muscles have been fixed to the head.
