Method for modeling a glenoid surface of a scapula, apparatus for implanting a glenoid component of a shoulder prosthesis, and method for producing such a component

A surgical apparatus for implanting a glenoid component of a shoulder prosthesis, the apparatus comprising:

• position-finding means for spatially locating a scapula of a patient;
• mapping means for mapping a glenoid surface of the scapula;
• modeling means for implementing the modeling method of claim 1 and thereby obtaining a theoretical glenoid surface from cartographic data of the glenoid surface supplied by the mapping means;
• first means of determination for determining a spatial position of a lower reference point for implanting the glenoid component from the cartographic data obtained at a lower end of the glenoid surface by the mapping means;
• and
• means of implantation for obtaining a spatial implantation configuration of the glenoid component from at least the theoretical glenoid surface and the lower reference point.
