Which does not qualify for a reverse total shoulder arthroplasty (RTSA)?

Which does not qualify for a reverse total shoulder arthroplasty (RTSA)?

• A. Small, repairable cuff tear
• B. Rotator cuff arthropathy
• C. Dysfunctional subscapularis
• D. Proximal humerus fracture

Answer: (A)

RTSA is used when the rotator cuff is severely damaged and cannot provide a stable, functional joint al-lowing the deltoid to lift the arm. This design is particularly helpful in cuff tear arthropathy with pseudoparalysis and in certain complex proximal humerus fractures where the rotator cuff is irreparable or nonfunctional. A small, repairable cuff tear, on the other hand, is treated best with tendon repair or non-reverse options because the rotator cuff can be restored to normal anatomy and function, making a reverse prosthesis unnecessary and less favorable. So the scenario of a small, repairable cuff tear does not qualify for RTSA, whereas the other situations align with its intended indications.
