The coracoacromial ligament transfer and the lateral portion of the clavicle removal are done to reconstruct the torn coracoclavicular ligaments. The absence of AC shock can also protect the surgery and fibrous tissue that grows in AC space and can also work as a shock absorber. Metallic suture anchor stabilization is used to protect the ligament transfer. The coracoacromial ligament is dissected from the undersurface of the acromion and is reinserted on the lateral clavicle by transosseous suture fixation. We achieved a very satisfactory reduction of the dislocated AC joint, reproducing the results achieved in open surgery. © 2010 Lippincott Williams & Wilkins, Inc.
