In this procedure, the provider performs a release of the coracoacromial ligament to restore shoulder function when the patient experiences a stiff, painful, or frozen shoulder. The provider may perform acromioplasty, a process in which the provider shaves a portion of the bone from the underside of the acromion process to release the abnormal pressure that it might be causing on underlying muscle or tendon.

Hold the bit with pliers, reverse the gun for couple of times, and then try to pull it out. Might’ve just gotten jammed in the hex a little.

This series uses a ball detent to hold the bit. When you slide the knurled ring down the ball should loose its tension allowing the bit to come out. Rust or debris can jam the ball detent. You could have used the wrong bit too. Once you can pull the ring down grab the bit with some pliers to help pull it out.
