A medical procedure includes providing a prosthesis which includes (i) a body portion having a rear surface and a bearing surface, and (ii) an anchor peg including a shaft extending from the rear surface of the body portion, wherein the anchor peg includes a plurality of outwardly extending fins secured to the shaft, and further wherein the plurality of outwardly extending fins each possesses a first diameter. The medical procedure further includes creating an anchor hole in a natural bone, the anchor hole possessing a second diameter which is less than the first diameter. In addition, the method procedure includes positioning the anchor peg within the anchor hole so that each of the plurality of outwardly extending fins deforms so as to possess (i) a concave side which faces an open end of the anchor hole, and (ii) a convex side that faces a closed end of the anchor hole.

A glenoid component for securement to a glenoid surface of a scapula so as to provide a bearing surface for a head portion of a humerus includes a body portion having a first surface configured to contact the glenoid surface of the scapula and a second surface configured to receive the head portion of the humerus. The glenoid component also includes an anchor peg extending from the first surface of the body portion for penetrating the glenoid surface of the scapula so as to secure the body portion to the glenoid surface of the scapula. The anchor peg has a first end portion and a second end portion with the first end portion of the anchor peg being secured to the first surface of the body portion, and the second end portion of the anchor peg having a number of fins secured thereto. The glenoid component also includes a first stabilizing peg extending from the first surface of the body portion for penetrating the glenoid surface of the scapula so as to prevent movement of the body portion relative to the glenoid surface of the scapula. A method of securing a glenoid component to a glenoid surface of a scapula so as to provide a bearing surface for a head portion of a humerus is also disclosed.

A spreadable retractor for use in joint arthroplasty. The retractor includes a first arm having a first portion and a second portion that is movably coupled to the first portion. The second portion is also coupled to a first retaining member that is sized and shaped to retain a portion of a coracoid process. A second arm is also included in the retractor and is movably coupled to the first arm. The second arm has a first portion and a second portion that is movably coupled to the first portion. Also, the second portion is coupled to a second retaining member that is sized and shaped to couple to a resected humerus.
