Benefits of technology

The patent text describes a surgical method and instruments for fitting an inverted shoulder prosthesis that reduces interference between the scapula and the humeral part of the prosthesis. The method involves placing a graft on the scapula and then inserting a glenoid component with a convex articular surface to cover the graft. The graft is designed to match the glenoid surface and the glenoid part of the prosthesis. The method also includes lateralizing the glenoid component to reduce interference with the scapula and improve stability and mobility of the prosthesis. The graft can be taken from the patient's humerus, which helps to limit rejection and disease transmission. The method also includes shaping and cutting the bone matter to form the graft. Overall, the invention provides a safer and more efficient surgical method for fitting an inverted shoulder prosthesis.

Problems solved by technology

This interference between the humeral prosthetic part and the scapula limits the range of the adduction movement and may cause pain to the patient or even lead to the prosthesis becoming dislodged, in particular by osteolysis of the scapula.

Embodiment Construction

[0047]FIG. 1 shows a shoulder prosthesis 1 comprising a glenoid component 10 and a humeral component 20, respectively implanted in the scapula S and the humerus H of a patient's shoulder. The glenoid components shown herein are illustrated schematically. The method and apparatus of the various embodiments disclosed herein may be used with a variety of other glenoid components, such as for example those disclosed in U.S. Pat. Nos. 7,033,396; 6,953,478; 6,761,740; 6,626,946; 5,702,447 and U.S. Publication Nos. 2004 / 0220673; 2005 / 0278030; 2005 / 0278031; 2005 / 0278032; 2006 / 0020344, which are hereby incorporated by reference.

[0048]The glenoid component 10 comprises a head 11, also described as a head structure, which has, on the side opposing the glenoid surface G of the scapula S, a convex articular surface 11A, also described as a face, of generally hemispherical shape and, on the side turned toward the glenoid surface, an opposing face 11B. In the example considered in the figures, thi...

Abstract

Method and set of surgical instruments for fitting a shoulder prosthesis, and the shoulder prosthesis. The proposed method seeks to interpose a bone graft between the previously prepared glenoid surface of a scapula of a patient's shoulder and the face of a glenoid prosthetic component opposite the articular surface. The set of instruments permit the bone graft to be taken from the upper epiphysis of the humerus, either in situ or ex vivo.
