Abstract: Traumatic posterior dislocation of the shoulder is dif?cult to diagnose and to treat. There are series that describe that 60-80% of these are not diagnosed during the ?rst visit to the emergency room. In this way, it is frequent to ?nd dislocations after several days and sometimes weeks, which always makes the treatment more complex. Posterior dislocations are usually accompanied by a print fracture on the anterior surface of the humeral head, known as the “reverse Hill-Sachs injury.” This bone defect can “engage” into the posterior glenoid ridge and thereby lead to recurrent instability and progressive destruction of the joint. The authors describe a modi?ed arthroscopic McLaughlin procedure, which allows ?lling of the bone defect with the upper third of the subscapular tendon, avoiding recurrence of posterior instability. In addition, a repair of the posterior Bankart lesion and tenodesis of the long portion of the biceps tendon were performed. This technique, in addition to repairing the posterior chondro-labral lesion, creates a remplissage effect, which makes the repair stronger, representing an optimal procedure in the de?nitive treatment of recurrent posterior luxation. It is an entirely arthroscopic procedure, so it avoids the disadvantages of an open procedure.
