Reverse total shoulder arthroplasty (rTSA) initially faltered because of glenoid component failure. Modern design utilizes a large glenosphere component and relies upon a functional deltoid for arm elevation. We report novel use of rTSA to revise a chronically dislocating TSA. The patient underwent proximal humeral resection for chondrosarcoma, requiring sacrifice of the deltoid and all proximal insertions including the latissimus dorsi. Twoyears post-operatively, he had good stability, no pain, and was using his arm more than he had in years. rTSA is a salvage option for failed TSA, even with absent deltoid function and lack of a latissimus.
