Apparatus and method for securing a cementless glenoid component to a glenoid surface of a scapula

摘要

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.
