## Abstract

A method of preparing a shoulder to receive a glenoid component includes accessing a glenoid of a shoulder, positioning a distal portion and a proximal portion of a combination power extension/anti-rotation device on a guide wire positioned in the shoulder and reaming a hole in the shoulder using the combination power extension/anti-rotation device with the distal portion and the proximal portion positioned on the guide wire. The proximal portion is removed from the guide wire and pivoted with respect to the distal portion while the distal portion is still positioned on the guide wire. The picoted proximal portion is used to rotate an instrument to a first position and a bore is formed in the glenoid through the instrument with the instrument at the first position.

## Claims

### Claim 1

A method of preparing a shoulder to receive a glenoid component, comprising:
accessing a glenoid of the shoulder;
positioning a distal portion of a combination power extension/anti-rotation device on a guide wire positioned in the shoulder;
positioning a proximal portion of a combination power extension/anti-rotation device on the guide wire positioned in the shoulder;
reaming a hole in the shoulder using the combination power extension/anti-rotation device with the distal portion and the proximal portion positioned on the guide wire;
removing the proximal portion from the guide wire;
pivoting the proximal portion with respect to the distal portion after removing the proximal portion and while the distal portion is still positioned on the guide wire;
rotating an instrument to a first position using the pivoted proximal portion; and
forming a first bore in the glenoid through the instrument with the instrument at the first position.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
maintaining the instrument at the first position using the pivoted proximal portion while forming the first bore.

### Claim 3 (depends on 1)

The method of claim 1, forming the first bore further comprising:
forming the first bore at a first location on the glenoid spaced apart from the reamed hole through a first drill guide extending through a body portion of the instrument.

### Claim 4 (depends on 3)

The method of claim 3, wherein the instrument further includes a second drill guide extending through the body portion of the instrument, the method further comprising:
forming a second bore at a second location on the glenoid spaced apart from the reamed hole and the first bore through the second drill guide.

### Claim 5 (depends on 4)

The method of claim 4, wherein the instrument further includes a third drill guide extending through the body portion of the instrument, the method further comprising:
forming a third bore at a third location on the glenoid spaced apart from the reamed hole, the first bore, and the second bore through the third drill guide.

### Claim 6 (depends on 3)

The method of claim 3, wherein reaming the hole in the shoulder further comprises:
transferring torque from the proximal portion to the distal portion through a first pair of tines associated with the proximal portion and through a second pair of tines associated with the distal portion.

### Claim 7 (depends on 6)

The method of claim 6, wherein pivoting the proximal portion with respect to the distal portion further comprises:
pivoting the proximal portion about a tine pin extending through at least one of the first pair of tines and at least one of the second pair of tines.

### Claim 8 (depends on 1)

The method of claim 1, further comprising:
decoupling the distal portion and the instrument while removing the proximal portion from the guide wire.

### Claim 9 (depends on 8)

The method of claim 8, further comprising:
recoupling the distal portion and the instrument using the pivoted proximal portion prior to rotating the instrument to the first position.
