1-37. (canceled)
A shoulder prosthesis for implantation in a patient, comprising:
- a shaft portion for attachment to a humerus shaft of the patient, wherein the shaft portion includes a proximal end and a distal end;
- a metaphyseal portion, wherein the metaphyseal portion includes a body, a proximal end and a distal end;
- a fin;
- and
- a flange portion;
- wherein the distal end of the metaphyseal portion abuts the proximal end of the shaft portion and the proximal end of the metaphyseal portion abuts the flange portion;
- wherein the fin extends from the metaphyseal portion in a generally anterior-lateral direction;
- wherein a free edge of the fin is offset in an anterior direction from a frontal plane of the prosthesis;
- and
- wherein a position of the free edge of the fin substantially mimics a position of essentially an entire anatomical location of a bicipital groove.
