  • Publication number: 20140081270
    Abstract: An instrument for use in preparing a graft. The instrument includes at least one cutting portion configured to resect a graft section from the graft. The instrument also includes a drive portion operably coupled to the cutting portion and configured to receive a rotational force. At least one reaming portion is positioned proximally to the cutting portion, the reaming portion is configured to ream a surface of the graft. The reaming portion and the cutting portion are positioned with respect to each other such that when the instrument is positioned against the graft and the rotational force is applied to the drive portion, the cutting section rotationally forms the graft section from the graft and the reaming portion rotationally reams a proximal section of the graft.

  • Publication number: 20140005789
    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.
