Treatment of a Failed Type V Acromioclavicular Separation Due to Coracoid Fracture: Revision of Acromioclavicular-Coracoclavicular Reconstruction and Coracoid Fixation

Acromioclavicular (AC) injuries are common, especially in the young and active population. AC joint dislocations account for 8% of all joint dislocations and are even more common in contact sports. These injuries are graded as type I through type VI on the basis of the Rockwood classification method. Types I and II are generally treated without surgery whereas types IV, V, and VI are best treated operatively. Type III dislocations remain controversial in terms of treatment, and many surgeons recommend nonoperative treatment first and operative treatment in case of continued symptoms such as pain, instability, or shoulder girdle dysfunction. The goal of operative treatment is to restore AC joint stability, which involves addressing both the coracoclavicular and coracoacromial ligaments to achieve a desirable patient outcome. The objective of this Technical Note is to describe our technique for management of a failed acromioclavicular stabilization, treated with a coracoclavicular and AC joint capsular reconstruction using tibialis anterior and semitendinosus allografts.
