Open Reduction of a Posteriorly Locked Shoulder Dislocation: A Case Example.

Summary: Posterior shoulder dislocations are uncommon but pose diagnostic and treatment challenges, particularly when locked due to humeral head impaction or soft tissue interference. These cases often necessitate surgical intervention, especially when locked or associated with recurrent instability or bony injuries. Preoperative assessment is vital to confirm the diagnosis and guide surgical planning. The surgical procedure begins with patient positioning and anesthesia, followed by a chosen approach, such as the deltopectoral route. In this case, exposure involved identifying and tenodesing the biceps tendon and performing a lesser tuberosity osteotomy. Reduction of the humeral head is achieved under direct visualization and confirmed with fluoroscopy. Stabilization is performed, and any associated lesions are addressed. Postoperative care involved immobilization and gradual rehabilitation. Consideration of patient age, chronicity, and associated bone loss helped dictate the appropriate intervention.
