Proceed with locking all variable angle screws used. Then slide the reaming guide into the reamer holder and depyu the two parts together by firmly tightening the upper round handle. The largest 42mm glenosphere is recommended by the manufacture if the size of the joint allows to increase both the overlap and the range of motion. The screw depth gauge can also be used to assess optimal screw length.
To obtain optimal compression of the metaglene plate on bone, alternate tightening of the superior and inferior locking screws. Repeat the same steps for the superior locking screw. For eccentric glenospheres, the vertical laser mark on the trial glenosphere should be aligned with the base of the coracoid superiorly and the depu neck inferiorly.
Inspect the exposed portion of the humeral component for cement and remove as necessary. Do so by inserting the hex head tip of the handle in the corresponding plate hole right or left depending on the shoulder being operated upon and lock the assembly by tightening the internal rod.

If necessary, remove the inferior retractor or sepuy the capsular release. After the two initial drapes are placed delfa the head shoulder and over the waist, one drape is place over the chest and feet.
Remove the resurfacing reamer, leaving the metaglene central guide pin in place. Select the appropriate proximal reaming guide size. Incising into anything medial to the lateral border of the conjoined tendon can result in musculocutaneous nerve injury. Check that the trial restrictor is firmly seated in the canal, then remove trial. Use the humeral cutting guide from the old DePuy Delta set to mark the cut angle on the humeral head.
The reamer is also power compatible, but CTA glenoids often are too soft for power. If you choose to lock your screws onto the driver, you will need to loosen the locking inner screws of each locking screw and retighten the outer screws.
