A sterile implantable component of a total shoulder prosthesis intended to be used in the revision surgery of a reverse shoulder prosthesis to avoid replacement of the humeral body/stem by enabling articulation between a reverse shoulder body and a standard humeral head [typically a cuff tear arthropathy (CTA) head]. It is a double male taper made of metal [e.g., cobalt-chrome-molybdenum (Co-Cr-Mo), or titanium (Ti)] and is used in a modular shoulder replacement system.
