Abstract

A glenoid component for securement to a glenoid surface of a scapula comprises a body portion having a first surface adapted to contact the glenoid surface of a scapula and a second surface configured to receive the head portion of a humerus. The glenoid component further includes an anchor peg 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 includes a cylindrical shaft extending from the first surface of the body portion and a fin secured to and extending outwardly from the cylindrical shaft. The glenoid component further includes a feature that prevents rotation of the glenoid component.

[0001] Cross References to Related US Patent Applications [0002] This application claims priority under 35 U.S.C. §119 to U.S. Patent Application No. 61 / 665,633, filed June 28, 2012, and entitled "MODIFIED GLENOID COMPONENTS AND METHODS OF INSTALLING SAME." The disclosure of this application is incorporated herein by reference. technical field [0003] The present disclosure relates generally to glenoid components, and more particularly, to glenoid components that resist rotation and pull-out and methods of installing the same. Background technique [0004] During the patient's lifetime, the patient may have to undergo total shoulder replacement surgery as a result, for example, of disease or trauma. In total shoulder replacement surgery, a humeral component with a head is used to replace the upper limb bone or the natural head of the humerus. The humeral component typically has an elongated intramedullary rod that is used to secure the humeral component to the patient's...
