Acromioclavicular (AC) Dislocation Repair Rehab Protocol

An acromioclavicular (AC) joint dislocation, or “separated shoulder,” is not truly an injury to the shoulder joint itself, but of the ligaments that attach the clavicle to the scapula. This injury commonly occurs from a direct blow to the shoulder such as a fall during sporting activity. A mild sprain involves the AC ligaments that attach the clavicle to the top portion of the scapula called the acromian. Severe injuries rupture both the AC ligaments as well as the coracoclavicular (CC) ligaments that attach the undersurface of the clavicle to the scapula. There is a sensation of a “sagging shoulder” as the weight of the arm pulls the scapula down away from the clavicle, causing a noticeable bump deformity the top of the shoulder. Mild sprains can be treated conservatively with rest, therapy, and time. More severe injuries require surgery to restore the anatomic relationship of the clavicle and scapula to optimize shoulder function.

The AC joint is reconstructed using a combination of strong sutures and buttons to restore the scapula height to the clavicle and in more chronic injuries a tendon graft may be necessary to reinforce the construct. Direct visualization and intraoperative x-ray help ensure adequate restoration AC joint. The goal of surgery is to restore the anatomic length of the clavicle to ensure return of shoulder motion and arm strength over time. This surgery can be performed as an outpatient, getting you home the same day.
