Osteonecrosis of the Humeral Head Following Anterior Shoulder Dislocation in a Dialysis-Dependent Patient

Case: A 75-year-old woman on long-term hemodialysis sustained anterior shoulder dislocation without a fracture. Four months later, she presented with persistent shoulder pain and limited motion. Imaging revealed humeral head osteonecrosis (Cruess stage V) and a massive rotator cuff tear. Reverse shoulder arthroplasty was performed with favorable outcome. Conclusion: Osteonecrosis of the humeral head following anterior shoulder dislocation without a fracture is rare. To our knowledge, this is the first reported case in a dialysis-dependent patient. This case highlights the need for increased clinical awareness regarding this complication in such patients.
