Two fingers on one hand are locked in a position that allows some hand function.
Medical records documenting which specific fingers are ankylosed and confirming that the ankylosis is favorable — meaning only one joint per digit is fixed, and the fingertip can come within two inches of the proximal transverse crease of the palm when flexed — support a rating under this code. For the thumb, records showing only one joint is ankylosed and the thumb pad can come within two inches of the fingers when attempting opposition also support a favorable finding.
Examination findings that identify the affected hand as your major or dominant hand or your minor or nondominant hand are relevant because some rating levels differ between the two. Imaging such as X-rays can document the fixed joint positions and rule out rotation or angulation of bone, which would change the evaluation. Statements from you or people who know you describing how the stiffened fingers affect grip, fine motor tasks, or work duties can help show the practical impact of the condition, which may be relevant when VA weighs the overall level of disability.
