Abstract

Background: Rotator cuff arthropathy associated with pathological fractures and bone lesions presents a complex therapeutic challenge. Management must address joint dysfunction, structural compromise, and the nature of the underlying lesion.

Case presentation: A 61-year-old female with chronic right shoulder pain was diagnosed with rotator cuff arthropathy, a pathological humeral fracture, and a diaphyseal aneurysmal bone cyst. A single-stage reverse total shoulder arthroplasty with a long-stem prosthesis was performed to address all three pathologies concurrently. The procedure proceeded without complications. At five months postoperatively, the patient achieved a Constant Score of 89, indicating excellent functional recovery.

Conclusion: Reverse shoulder arthroplasty with a long stem can be considered and safe surgical option in complex cases involving degenerative arthropathy, pathological fracture, and bone lesions, even in the absence of malignancy. This approach broadens the indications for reverse shoulder arthroplasty in non-oncologic scenarios
