Acromioclavicular joint injuries are relatively common traumas particularly seen in contact sports and skiing, skateboarding and cycling. The severity of injury is determined by the level of laceration of coracoclavicular ligaments and displacement of clavicula. According to Rockwood classification system, the first line treatment modality of type I and II injuries are non-operative. On the other hand, choice of treatment for type III (the most diagnosed type) and type V is controversial for years despite increasing knowledge about biomechanics of the joint. All types of surgical procedures have got two steps: reduction of the clavicle and repair, augmentation or reconstruction of coracoclavicular ligament in order to maintain the reduction. Open reduction and fixation with hook plates or coracoclavicular screws and button-suture methods for coracoclavicular ligament augmentation are applied in acute period. Besides, Weaver-Dunn procedure which includes distal clavicula excision and coracoacromial ligament transfer has been modified with additional steps because of the high failure rates. In addition, some other procedures like coracoclavicular ligament reconstruction by using allo/autografts could be used alone or with the other methods to keep joint reduced. Recently, some studies claim that there is no statistically significant functional differences between patients treated with surgery or conservative methods. That`s why, some variables like type and time (acute or chronic) of injury, preferences and expectations of the patient should be considered in order to decide the treatment.
