6. An orthopaedic glenoid prosthesis for implantation into a glenoid surface of a scapula so as to provide a bearing surface for a natural or prosthetic head of a humerus, the glenoid prosthesis comprising:
-
a metallic defect-filling component sized and shaped to fit and be implanted within a defect in the glenoid surface, the metallic defect-filling component having a plurality of holes extending therethrough, the plurality of holes being arranged in a hole pattern, and a polymer glenoid component, the polymer glenoid component being discrete from the metallic defect-filling component and having (i) a bearing surface configured to articulate with the head of the humerus, and (ii) an engaging surface that is opposite the bearing surface, the engaging surface comprising a plurality of pegs arranged in a peg pattern that corresponds to the hole pattern of the metallic defect-filling component. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 18, 19)

14. An orthopaedic glenoid prosthesis for implantation into a glenoid surface of a scapula so as to provide a bearing surface for a natural or prosthetic head of a humerus, the glenoid prosthesis comprising:
-
a metallic defect-filling component sized and shaped to fit and be implanted within a defect in the glenoid surface, the metallic defect-filling component having (i) a first hole positioned in the center of the metallic defect-filling component, and (ii) a second hole positioned between the center and an edge of the metallic defect-filling component; and a polymer glenoid component secured to the metallic defect-filling component, the polymer glenoid component being discrete from the metallic defect-filling component and having (i) a bearing surface configured to articulate with the head of the humerus, and (ii) an engaging surface that is opposite the bearing surface, the engaging surface comprising (a) an anchor peg positioned in a center of the polymer glenoid component and extending into the first hole of the metallic defect-filling component so as to secure the polymer glenoid component to the metallic defect-filling component, and (ii) a stabilizing peg positioned between the center and an edge of the polymer glenoid component and extending into the second hole of the metallic defect-filling component to prevent rotation of the polymer glenoid component. - View Dependent Claims (15, 16, 17)
