Abstract
A reverse modular humeral implant for implantation into a humerus that includes a natural humeral shaft and a natural humeral head.

Claims1
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;
- 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.
