Abstract: The invention is a modular composite shoulder prosthesis 64, whose construct incorporates a solid autogenous bone graft 50 to be used to replace the upper humerus in certain fracture types. The prosthesis comprises a stem 22 to be inserted in the canal of the humerus, an intermediary part reduced to a medial pillar 24 and a head which is a generally spherical cap 20 that is hollow. The head of the prosthesis being hollow and coated with an osteoconductive material, the lateral aspect of the medial pillar as well as the upper part of the stem being also coated with the same material, an epiphyso-metaphyseal space is delineated in which a solid autogenous bone graft is fitted. Union can be achieved between the coated parts of the prosthesis, the bone graft 50 and the tuberosities reattached to the humerus shaft, secured to holes 62 of the medial pillar and between themselves.

Abstract: A glenoid plastic prosthesis 100 for cementation is described, comprising a pear-shaped body having a concave articular face 26 and a convex face with a horizontal keel 28 and threaded pegs 34. Indentations 30 on the keel and the convex surface of the implant follow a generally fractal pattern in order to increase the implant cement interface. Tools are provided such as a) A glenoid-marking tool 58 used to stamp into the glenoid subchondral bone patterns of indentations of a generally fractal nature and b) A glenoid indentation tool used to make indents in walls of the glenoid cavity for the keel in order to increase the bone-cement interface.

Abstract: The invention relates to a shoulder-joint endoprosthesis comprising a glenoid joint socket having a rearward part which has a porous structure for attachment to the shoulder blade. The socket is dished and substantially pear shaped. A humeral joint socket is fixed to the humerus by way of an intramedullary prosthesis stem. A joint ball is disposed between the glenoid joint socket and the humeral joint socket so as to be freely movable.
