Abstract
Locked posterior shoulder dislocations are dislocations that remain unreduced for more than three weeks. In most cases, they are associated with other injuries. We report the case of a 38-year-old male who presented with pain and total functional impotence due to a complex injury, including posterior glenohumeral dislocation, a reverse Hill-Sachs lesion, and a clavicle fracture. Because of the unsuccessful attempts at closed reduction, the patient underwent surgery. We performed the McLaughlin technique, which included the transfer of the subscapularis tendon to the reverse Hill-Sachs lesion, stabilized by bone anchors. At the last follow-up, the patient was doing well and had regained full range of motion with no recurrent dislocation. Clinicians should maintain clinical and radiological suspicion about this injury to timely manage this rare and dangerous injury.
