摘要： A prosthetic glenoid component has a body having a concave bearing surface and a convex glenoid contacting surface. First and second pegs extend outwardly from adjacent respective first and second ends of the bone contacting surface of the body, the first and second pegs have portions with a first diameter at the bone contacting surface extending for a first length and a second diameter extending from the first diameter for a second length, the first diameter larger than the second diameter. A third peg extends outwardly from the bone contacting surface intermediate the first and second pegs. The third peg has a third diameter greater than the second diameter portion of the first and second pegs and a third length greater than the first length of the first diameter portion of the first and second pegs. The third length is less than the sum of the first and second lengths.
