Concomitant Acromioclavicular and Coracoclavicular Ligament Reconstruction with a Duo-Figure-8 Autogenic Graft Wrapping Technique for Treating Chronic Acromioclavicular Separation.

The technique yielded acceptable functional outcomes in patients with anatomic reduction or partial loss of reduction. The "duo-figure-8" wrapping method-a single autogenic tendon graft passing beneath the coracoid process with a tendon-knot fixation over the distal clavicle and looping around the acromion intramedullary-did not increase the risk of peri-tunnel fractures over the clavicle, coracoid process, or acromion.
