Abstract

A glenoid implant is provided and may include a body portion and a stem portion. The stem portion may extend from the body portion along a longitudinal axis. The body portion may include an articular side and a bone-engaging side opposite the articular side. At least a portion of the bone-engaging side may be disposed at a non-parallel angle relative to at least a peripheral edge of the articulation side.

Claims (30)

1. A glenoid implant, comprising:

a body portion including an articular side, a bone-engaging side opposite the articular side, and a longitudinal axis extending through the articular side and the bone-engaging side;

a plurality of fastener apertures extending through the body portion between the articular side and the bone-engaging side, the fastener apertures being sized and shaped to receive bone fasteners to secure the glenoid implant to a bone, wherein the plurality of fastener apertures includes at least three apertures; and

a plurality of removable bone-engaging projections extending from the bone-engaging side of the body portion, each of the bone-engaging projections including a head portion that is configured to be received within one of a plurality of projection apertures formed in the bone-engaging side of the body portion.

2. The glenoid implant of claim 1 , wherein the plurality of fastener apertures have a same size.

3. The glenoid implant of claim 1 , wherein the plurality of fastener apertures are spaced apart around the longitudinal axis of the body portion.

4. The glenoid implant of claim 1 , wherein at least one fastener aperture of the plurality of fastener apertures extends through the body portion in a direction that is substantially parallel to the longitudinal axis.

5. The glenoid implant of claim 1 , wherein at least one fastener aperture of the plurality of fastener apertures extends through the body portion in a direction that is angled with respect to the longitudinal axis.

6. The glenoid implant of claim 1 , wherein the articular side of the body portion includes an outer peripheral edge that is substantially perpendicular to the longitudinal axis.

7. The glenoid implant of claim 1 , wherein the plurality of fastener apertures includes at least four apertures.

8. The glenoid implant of claim 1 , wherein at least one of the plurality of bone-engaging projections is coated with a porous material.

9. The glenoid implant of claim 1 , wherein each one of the plurality of bone-engaging projections is disposed between an adjacent pair of the plurality of apertures.

10. The glenoid implant of claim 1 , further comprising an opening extending through the articular side into the body portion.

11. The glenoid implant of claim 10 , wherein the opening is centered along the longitudinal axis of the body portion.

12. The glenoid implant of claim 10 , wherein the opening extends through the bone-engaging side of the body portion.

13. A glenoid implant, comprising:

a body portion including an articular side, a bone-engaging side opposite the articular side, and a central longitudinal axis extending through the articular side and the bone-engaging side, at least a portion of the bone-engaging side defining a porous surface configured to promote bone in-growth;

a plurality of apertures extending through the body portion between the articular side and the bone-engaging side, the apertures being sized and shaped to receive bone fasteners to secure the glenoid implant to a bone, wherein the plurality of apertures includes at least three apertures;

a plurality of openings extending at least partially through the body portion; and

a plurality of bone-engaging projections removably couplable to the plurality of openings such that the bone-engaging projections extend from the bone-engaging side of the body portion.

14. The glenoid implant of claim 13 , wherein at least one aperture of the plurality of apertures extends through the body portion in a direction that is substantially parallel to the central longitudinal axis.

15. The glenoid implant of claim 13 , wherein at least one aperture of the plurality of apertures extends through the body portion in a direction that is angled with respect to the central longitudinal axis.

16. The glenoid implant of claim 13 , wherein the plurality of apertures includes at least four equally sized and spaced apertures.

17. The glenoid implant of claim 13 , wherein each one of the plurality of bone-engaging projections is disposed between an adjacent pair of the plurality of apertures.

18. The glenoid implant of claim 13 , further comprising a plurality of bone fasteners, wherein at least one of the bone fasteners comprises a fixation peg including a porous shaft.

19. A glenoid implant, comprising:

a body portion including an articular side, a bone-engaging side opposite the articular side, and a longitudinal axis extending through the articular side and the bone-engaging side, at least a portion of the bone-engaging side defining a porous surface configured to promote bone in-growth;

a plurality of threaded apertures extending through the body portion between the articular side and the bone-engaging side, the apertures being sized and shaped to receive bone fasteners to secure the glenoid implant to a bone;

a plurality of bone-engaging projections removably couplable to the body portion and configured to extend from the bone-engaging side of the body portion, the bone-engaging projections securable to the body portion from the bone-engaging side by inserting a head portion of the bone-engaging projection into an opening formed in the bone-engaging side; and

a plurality of bone fasteners, wherein at least one of the bone fasteners comprises a fixation peg including a threaded head and a porous shaft.
