Three fingers on one hand are locked in a position that allows some hand function.
Medical records and examination findings are central to supporting a rating under this code. An examiner will need to document which three digits are affected and which hand is your major or minor hand. Range-of-motion testing showing that only one joint per affected digit — either the metacarpophalangeal or proximal interphalangeal joint — is locked, and that each locked joint is fixed in the position of function, supports a favorable rather than unfavorable finding.
A key measurement is the gap between each affected fingertip and the proximal transverse crease of the palm when the finger is flexed as far as possible. A gap of two inches or less supports favorable ankylosis. X-rays can help confirm the presence and position of ankylosis. Statements from you or people who see you regularly can document how the stiffness in those three fingers affects tasks at work or in daily life that require gripping, pinching, or fine hand control.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
