Abstract: A glenoid prosthesis includes a head portion and an anchor. The head portion includes a first surface adapted to contact a glenoid and an opposed second surface that is at least partially concave. The anchor extends from the first surface of the head portion and terminates at a distal end. At least one first circular member is disposed between the head portion and the distal end of the anchor and encircle the anchor. At least one second circular member is disposed between the head portion and the distal end of the anchor and encircles the anchor. The at least one first circular member is adapted to engage cortical bone of a glenoid and the at least one second circular member is adapted to engage cancellous bone of a glenoid when the glenoid prosthesis is implanted.

Abstract: Guides for guiding a tool into a medullary canal of a bone. The guides can include a base and a guide feature. The base can include a first surface configured to contact the bone and a second surface opposite the first surface. The guide feature can be disposed to guide the tool along a central portion of the medullary canal.

Abstract: A method of fixating a prosthesis to a glenoid is disclosed. The method includes forming a bore in the glenoid; positioning the prosthesis adjacent the glenoid, where the prosthesis includes a head portion and an anchor extending from a rear surface of the head portion; wherein the anchor includes a first fin and a second fin proximal of the first fin; advancing the anchor into the bore until the first fin is implanted within cancellous bone; and further advancing the anchor in the bore until a proximal-facing surface of the second fin is implanted within cancellous bone and abuts cortical bone.

Abstract: A method of fixating a prosthesis to a glenoid includes drilling a first hole in a central portion of the glenoid; and inserting a stem of the prosthesis into the first hole until at least one first deformable fin that encircles the stem engages cortical bone and at least one second deformable fin that encircles the stem engages cancellous bone, the prosthesis including a head portion having a first outwardly curved surface and an inwardly curved surface that is sized and configured to engage at least one of a humerus or a humeral component, wherein the stem is formed from a first material and the head portion of the prosthesis is defined from a second material that is different from the first material.
