Project Description

Injuries to the acromioclavicular (AC) joint are common, particularly in the young and active population. Type I and II injuries are typically treated nonoperatively, while type IV–VI injuries are most often treated surgically. A variety of surgical techniques have been described, including anatomic and non-anatomic reconstruction. However, up to 80% go on to lose radiographic reduction, and between 20% and 30% have complications leading to reoperation. This is my preferred technique for the treatment of AC joint instability in the revision setting. This technique utilizes a Dog Bone™ Button (Arthrex, Inc, Naples, FL) and two allografts, and reconstructs both the CC ligaments and AC joint capsule.  This is unique in that the grafts are incorporated into the AC joint for added stability.  We have shown this in our lab to be the most robust construct, especially to keep the clavicle from translating posteriorly and causing pain and dysfunction.
