Abstract: A joint prosthesis implant having: a main body made mainly of ceramic and including a joint outer surface made of ceramic, of concave or convex shape, at least one tightening screw configured to tighten the main body on the patient's bone or on an intermediate element attached to the bone, at least one added ring in the main body configured to homogeneously distribute in the main body the mechanical stresses caused by tightening the tightening screw, the added ring having a first member and a second member separate from each other.

Abstract: A glenoid implant for reverse shoulder prosthesis, having a base for anchoring the implant to a bone formed by a rod configured to extend through the thickness of the bone from a glenoid fossa, the rod including through-holes, and by screws for anchoring the rod configured to cross radially the rod, via the through-holes, and the bone, when the glenoid implant is implanted on the bone.

Abstract: The invention relates to a joint prosthesis implant (1) made mainly of ceramic and having a housing (4) on its joint outer surface (8) and an assembly (100) of such an implant (1) and a gripping device (20).

Abstract: The invention relates to a method and a device for manufacturing an articular prosthesis implant using a mould comprising a ceramic imprint (1) moved by a piston (2), the ceramic imprint (1) pressing the thermoplastic material introduced into the mould.

Abstract: The invention relates to a glenoid trial implant for reverse total shoulder prosthesis including a metaglene intended to be assembled in a stabilized and temporary manner inside the glenoid fossa of a patient who will receive surgery, and a glenosphere integrally assembled to the metaglene.

Abstract: A set of reconstruction includes an element of reconstruction (1) having a base part (11) and an upper part (10) connected to the base part (11) or intended to be connected to this base part (11); the base part (11) includes elements (12, 25, 26) for its mounting on the external side of the humeral implant (2); it is sized to project, after installation on the humeral implant (2), beyond the external surface (2a) of the humeral implant (2) and beyond at least one of the anterior (2b) or posterior (2c) surfaces of this humeral implant (2), on the outer side of these surfaces; and the upper part (10) forms an outer external curved surface extending, after mounting on the humeral implant (2), away from the external surface (2a) of this humeral implant (2) and from at least one of the anterior or posterior surfaces of this humeral implant.
