Open Anatomic Coracoclavicular Ligament Reconstruction for Acromioclavicular Joint Injuries.

Open reconstruction of the coracoclavicular (CC) and acromioclavicular (AC) ligaments results in excellent reduction of severely displaced AC dislocations, most commonly Grades III and V. Anatomic CC reconstruction through clavicular bone tunnels can prevent vertical instability, whereas the addition of an acromial limb of the graft can increase horizontal stability. Autograft tendon is preferred in the young athletic group of collision sports participants, although allograft has had acceptable results. Accessory fixation may be placed to protect the graft during healing, or for severe instability, especially for athletes involved in contact sports.
