Figure 5: (a)The guide is rotated to capture the anterior edge of the glenoid under the hook. The hook should be placed at the 4 o'clock position which will correlate with the mid point of the coracoid. The Glenoid Guide should also align with the placement of the spinal needle. (b) Once the hook is positioned, a bullet is placed in the superior hole of the guide. A small skin incision is made and the bullet is advanced until it firmly contacts the posterior aspect of the glenoid neck. The ratchet teeth of the bullet should be aligned with the screws adjacent to the handle of the guide. The process is repeated for the inferior bullet.
