Abstract: The glenohumeral component of the invention comprises a first side and a second side, which are opposite each other and which, in an implanted state in which the glenohumeral component is free-floating with respect to a humerus and a glenoid of a human shoulder, are in contact respectively with an end portion of the humerus and with a glenoid component intended to be secured to the glenoid. The first side of the glenohumeral component includes a convex articular surface that is designed to articulate with a concave bone surface prepared within the end portion of the humerus. The second side of the glenohumeral component includes a concave articular surface that is designed to articulate with a convex articular surface of the glenoid component. The corresponding shoulder prosthesis is thus reversed.
