Acromioclavicular (AC) dislocations are common shoulder injuries. The classic mechanism of injury to AC joint is direct trauma caused by falls or blows to acromion with the arm abducted. According to Tossy et al,1 the degrees of AC dislocations are classified into types Ⅰ, Ⅱ, and Ⅲ. Tossy Ⅰ and Ⅱ are incomplete dislocations. Tossy Ⅲ is a complete dislocation with complete disruption of the AC and coracoclavicular (CC)ligaments, accompanied by marked upward migration of the lateral end of the clavicle. Typically, surgical treatment is needed for patients with Tossy Ⅲ. It is the best solution to restore the anatomy of AC joint. There are many surgical techniques that had been described in the preceding articles. Every surgical method has its limitations.
