ABSTRACT:
A modular humeral prosthesis including a humeral stem for anchoring which stem includes a bearing face, a spacer in the form of a wedge having a first face which fits on the bearing face of the stem and a second face, and a humeral semi-spherical cap having a base which is fixed with respect to the second face of the spacer. The manner in which the cap and spacer are connected relative to the bearing face of the stem permits the cap to be adjusted angularly in position about an axis which is off-set from the axis of symmetry of the cap. Elements are provided to lock the cap to the spacer and the spacer to the stem.
