Biplanar Reconstruction With Pectoralis Minor Tendon and Coracoacromial Ligament Transfer for Chronic Acromioclavicular Joint Dislocations.

Acromioclavicular joint dislocation is a common pathology, affecting mostly young male patients. High-grade injuries require surgical treatment, but evidence is lacking regarding a gold standard technique. Chronic cases frequently are treated with graft reconstruction, but complications and availability remain as a limitation for autograft and allograft use, respectively. The objective of this Technical Note is to describe the treatment of chronic acromioclavicular dislocations by a reconstruction made with a local tendon graft, the pectoralis minor, in addition to transferring the coracoacromial ligament as a horizontal stabilizer.
