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.
Claims22
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, the glenoid component comprising:
- a body portion having (i) a first surface adapted to contact the glenoid surface of a scapula and (ii) a second surface configured to receive the head portion of the humerus;
- and
- 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, wherein the anchor peg includes (i) a cylindrical shaft extending from the first surface of the body portion and (ii) a fin secured to and extending outwardly from the cylindrical shaft, the fin being generally square-shaped.
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, the glenoid component comprising:
- a body portion having (i) a first surface adapted to contact the glenoid surface of a scapula and (ii) a second surface configured to receive the head portion of the humerus;
- 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, wherein the anchor peg includes (i) a cylindrical shaft extending from the first surface of the body portion and (ii) a fin secured to and extending outwardly from the cylindrical shaft;
- and
- at least one gusset secured to and extending downwardly from the first surface of the body portion and secured to and extending outwardly from the cylindrical shaft of the anchor peg.
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, the glenoid component comprising:
- a body portion having (i) a first surface adapted to contact the glenoid surface of a scapula and (ii) a second surface configured to receive the head portion of the humerus;
- 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, wherein the anchor peg includes (i) a cylindrical shaft extending from the first surface of the body portion and (ii) a fin secured to and extending outwardly from the cylindrical shaft, wherein the fin includes at least one cutout configured to allow the fin to deflect outwardly along a hole in which the glenoid component is secured, thereby preventing rotation of the glenoid component.
A tool for preparing a glenoid surface of a scapula, the tool comprising:
- a handle;
- and
- a punch operatively connected to the handle, wherein the fin punch includes a plate having a cylinder extending from the disc and at least one gusset extending outwardly from the cylinder.
