A computer-modeled range of motion study of reverse shoulder arthroplasty in osteoarthritic shoulders with severe posterior glenoid erosion (Walch B2, B3, C). Using CT-based simulation, it asks which glenoid version, glenoid lateralization, and humeral neck-shaft angle maximize bone-constrained prosthetic motion. The goal is to guide component choice when heavy reaming of an eroded glenoid threatens to medialize the joint and worsen impingement.
