Reverse shoulder prosthetic

摘要

A reverse modular humeral implant for implantation into a humerus that includes a natural humeral shaft and a natural humeral head. The implant includes a humeral stem implantable into the natural humeral shaft, and an adapter couplable to the humeral stem, the adapter including an anchoring projection configured to be coupled to a convex bearing.

主权项

1. A method of implanting a shoulder prosthetic comprising:
implanting a glenoid tray into a resected glenoid; engaging a planar surface of a bearing coupling member with a bearing mount surface of the glenoid tray; fixing the bearing coupling member to the glenoid tray using a fastener; restricting relative rotation between the glenoid tray and the bearing coupling member with a bushing member disposed about the bearing coupling member, the bushing member having a plurality of planar bore surfaces engaging corresponding planar surfaces of the bearing coupling member; inserting a locking member of a coupling flange of the bearing coupling member into an interior coupling bore of the glenoid tray; engaging the locking member with a locking surface formed between first and second portions of the interior coupling bore; and mating a coupling surface of the bearing coupling member with a corresponding surface on a bearing member.
