They are associated with a horizontal imbalance of the shoulder, causing pain and limitation of active internal rotation. Historically, the alternative for these patients has been transfer of the pectoralis major, with all its variations, total or partial, up or under the conjoint tendon. However, this transfer has mechanical disadvantages, especially related to the vector of traction, because it originates in the anterior region of the chest. In 2013, Elhassan and colleagues demonstrated in cadavers the technical feasibility and neurological safety of performing transfers of the latissimus dorsi (LD) to the lesser tuberosity to reconstruct irreparable lesions of the subscapularis. This option, compared with alternatives, has superior biomechanical advantages such as a similar vector of traction, originating from lower and posterior to the thorax, in addition to involving a synergistic muscle in action. In early 2016, Kany and colleagues first published a study of 5 patients undergoing arthroscopic assisted LD to SS transfer, with promising results. Our purpose is to present an arthroscopically assisted latissimus dorsi transfer technique in patients with irreparable subscapularis rupture.enArthroscopyIrreparableLatissimusSubscapularisTransferArticle
