Open Anatomic Coracoclavicular Ligament Reconstruction by Modified Conjoint Tendon Transfer for Treatment of Acute High-Grade Acromioclavicular Dislocation

Sumario: | There is no ideal surgical technique for the treatment of acromioclavicular (AC) dislocations. Reconstruction of the coracoclavicular ligaments (CCLs) for the treatment of AC dislocations is evolving. Many techniques for CCL reconstruction have been described. They differ mainly in the method of fixation, number of tunnels, and graft used. The surgeon should select among hamstring autograft reconstruction, coracoacromial ligament transfer, and conjoint tendon transfer for CCL reconstruction. Early on, conjoint tendon transfer to the lateral clavicle was described for the treatment of high-grade AC dislocation. Dynamic instability occurred with poor long-term outcomes. The procedure was abandoned. Recently, proximally based conjoint tendon transfer for CCL reconstruction was described, but the technique is nonanatomic and leads to anterior displacement of the clavicle and malreduction. This article describes modified conjoint tendon transfer. The technique may yield stable, anatomic, biological reconstruction of the CCL for the treatment of acute high-grade AC dislocation. It consists of the following steps: (1) creation of clavicular holes, (2) coracoid osteotomy, (3) conjoint tendon mobilization, (4) conjoint tendon transfer and fixation to the CCL footprint on the undersurface of the clavicle, and (5) AC reduction and conjoint tendon tenodesis to the bed of the retained coracoid process. |
