## Abstract

A kit for making a glenoid prosthesis. The kit includes an articulating member having an articulation side and an opposing second side opposing the articulating member. The opposing second side includes a locking mechanism. The kit further includes a plurality of bases, and each of the plurality of bases having an articulating-member facing side and a glenoid attachment side. Each of the plurality of glenoid attachment sides include at least one glenoid attachment member extending outwardly and sized and shaped to extend into a patient's glenoid. The glenoid attachment member of one of the plurality of bases differs from the glenoid attachment member of at least one other of the plurality of bases. Each of the plurality of bases includes a locking mechanism sized and shaped to lock each of the plurality of bases to the articulating member.

## Claims

### Claim 1

A kit for making a glenoid prosthesis, the kit comprising:
an articulating member having an articulation side and an opposing second side opposing the articulating member, wherein the opposing second side includes a locking mechanism; and
a plurality of bases, each of the plurality of bases having an articulating-member facing side and a glenoid attachment side, wherein each of the plurality of glenoid attachment sides include at least one glenoid attachment member extending outwardly and sized and shaped to extend into a patient's glenoid, wherein the glenoid attachment member of one of the plurality of bases differs from the glenoid attachment member of at least one other of the plurality of bases, and wherein each of the plurality of bases includes a locking mechanism sized and shaped to lock each of the plurality of bases to the articulating member, wherein the plurality of bases includes at least one finned peg and one wedge-shaped filler.

### Claim 2 (depends on 1)

The kit of claim 1, wherein the opposing second side of the articulating member includes a recess defined by three side-walls and having an opening opposite one of the three sidewalls.

### Claim 3 (depends on 1)

The kit of claim 1, wherein the base locking mechanism includes a locking recess and the articulation member locking mechanism includes a lip sized and shaped to fit into the locking recess.

### Claim 4 (depends on 1)

The kit of claim 1, wherein the base locking mechanism includes a pair of protrusions and the articulation member locking mechanism includes a pair of recesses sized and shaped to engage the protrusions.

### Claim 5 (depends on 1)

The kit of claim 1, wherein the plurality of bases further include a screw.

### Claim 6 (depends on 1)

The kit of claim 1, wherein the opposing second side of the articulating member includes a recess defined by two side-walls and being open on two sides.

### Claim 7 (depends on 6)

The kit of claim 6, wherein the articulating member locking mechanism includes a projection on the two open sides and the base includes two sides corresponding to the open sides of the articulating member locking mechanism and the two sides each includes a lip and a recess to engage the projection on the articulating member.

### Claim 8 (depends on 1)

The kit of claim 1, wherein the articulating member and plurality of bases are polyethylene.

### Claim 9 (depends on 8)

The kit of claim 8, wherein the articulating member and plurality of bases are UHMWPE.

### Claim 10 (depends on 1)

The kit of claim 1, wherein the base locking mechanism includes a locking recess and the articulation member locking mechanism includes a lip sized and shaped to fit into the locking recess.

### Claim 11 (depends on 1)

The kit of claim 1, wherein the base locking mechanism includes a pair of protrusions and the articulation member locking mechanism includes a pair of recesses sized and shaped to engage the protrusions.

### Claim 12

A kit for making a glenoid prosthesis, the kit comprising:
an articulating member having an articulation side and an opposing second side opposing the articulating member, wherein the opposing second side includes a locking mechanism; and
a plurality of bases, each of the plurality of bases having an articulating-member facing side and a glenoid attachment side, wherein each of the plurality of glenoid attachment sides differs from the glenoid attachment side of at least one other of the plurality of bases, and wherein each of the plurality of bases includes a locking mechanism sized and shaped to lock each of the plurality of bases to the articulating member, wherein the plurality of bases includes at least one finned peg and one wedge-shaped filler.

### Claim 13 (depends on 12)

The kit of claim 12, wherein the plurality of bases further include a screw.

### Claim 14 (depends on 12)

The kit of claim 12, wherein the articulating member and plurality of bases are polyethylene.
