Results of Acute Treatment of Reverse Hill-Sachs Lesion Associated With Locked Posterior Shoulder Dislocation With Modified McLaughlin Procedure: A Case Report and Literature Review

This case report evaluates the clinical outcomes of two patients with locked posterior shoulder dislocation associated with a reverse Hill-Sachs lesion who were operated on in the acute phase with a modified McLaughlin procedure. Both patients had dislocated posterior shoulder fractures affecting approximately 40% of the articular surface of the humeral head and could not be reduced in the emergency department. Both patients were operated on the same day of hospitalization. We analyzed the clinical and radiological results after at least three years of follow-up. Care should be taken not to overlook these rare injuries and difficult reduction maneuvers should be avoided in the emergency department. Reduction and articular surface reconstruction with the modified McLaughlin method can be performed in the same session and in the acute period. Acute treatment of the reverse Hill-Sachs lesion associated with locked posterior shoulder dislocation with the modified McLaughlin procedure is effective and safe. Further studies are needed to determine the optimal treatment of these very rare injuries.
