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.

A joint ball is disposed between the glenoid joint socket and the humeral joint socket so as to be freely movable.
