This surgical case demonstrates the conversion of a failed reverse total shoulder arthroplasty complicated by a chronic periprosthetic fracture nonunion to an allograft prosthetic composite (APC) hemiarthroplasty using a long-stemmed interlocking humeral prosthesis. Dr. Uma Srikumaran details the preoperative planning, surgical technique, graft preparation, and tendon transfers utilized to restore stability and function in a patient with significant proximal humeral bone loss.

This video presents a modified McLaughlin procedure performed for a locked posterior shoulder dislocation with a large reverse Hill-Sachs lesion in an active young adult. The procedure includes a lesser tuberosity transfer and a novel dual anchor and button fixation technique to restore humeral head stability. Dr. Uma Srikumaran discusses indications, surgical steps, fixation strategy, and postoperative management, offering insights into treating complex posterior instability.
