Posterior Fracture Dislocation of the Shoulder: A Modified McLaughlin Procedure.

Abstract

Bilateral posterior fracture dislocation is a rare injury commonly associated with seizures. When the humeral head defect (reverse Hill-Sachs lesion) is between 20% and 45%, operative fixation using a modified McLaughlin procedure is recommended. This video demonstrates a case of bilateral posterior fracture dislocation after a drug-induced seizure treated with a modified McLaughlin procedure. The original McLaughlin procedure involved transfer of the subscapularis tendon from the lesser tuberosity to the reverse Hill-Sachs defect. However, the modified McLaughlin procedure is more commonly described in the literature as of late and involved the transfer of the lesser tuberosity along with the subscapularis. This video demonstrates the modified McLaughlin technique for a posterior fracture dislocation. Computerized tomography confirms the articular impression fractures of the proximal humerus. Through a deltopectoral approach, the lesser tuberosity along with the subscapularis tendon was transferred into the defect. The modified McLaughlin procedure demonstrates excellent clinical and radiographic results after posterior fracture dislocation of the shoulder with a reverse Hill-Sachs lesion between 25% and 45%.
