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.
Claims19
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.

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.

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.
