Counter-Torque Revisable Stemless Shoulder Implant

A base member of a prosthetic stemless shoulder implant may include a proximal collar, a central anchor, and at least one peripheral anchor. The proximal collar may have a proximal surface and a distal bone-engaging surface opposite the proximal surface. The central anchor may extend distally from t...

Beschreibung
Zusammenfassung:	A base member of a prosthetic stemless shoulder implant may include a proximal collar, a central anchor, and at least one peripheral anchor. The proximal collar may have a proximal surface and a distal bone-engaging surface opposite the proximal surface. The central anchor may extend distally from the bone-engaging surface and define an opening extending from the bone-engaging surface into the central anchor for receiving a humeral head component of the prosthetic stemless shoulder implant. The at least one peripheral anchor may be positioned radially outwardly of the central anchor and extend distally from the bone-engaging surface. The peripheral anchor may be frangibly connected to the proximal collar.
