What evidence supports a higher rating for Ankylosis of thumb?

The key evidence for Ankylosis of thumb is documentation of how the condition affects daily functioning. For musculoskeletal conditions, range of motion measurements (active, passive, weight-bearing, and non-weight-bearing per Correia v. McDonald) and flare-up documentation are critical. A nexus letter from a qualified medical professional linking the current severity to service is essential for contested claims.

What happens at the C&P exam for Ankylosis of thumb?

The C&P examiner uses a Musculoskeletal System DBQ and evaluates your condition against the DC 5224 rating criteria. Expect range of motion testing in multiple positions. Under Correia v. McDonald, the examiner must test active, passive, weight-bearing, and non-weight-bearing range of motion. Report your worst flare-up symptoms — if you cannot attend during a flare, request the exam be rescheduled.
