All five fingers on one hand are locked in a position that allows some hand function.
Medical records documenting permanent stiffness in all five digits of the affected hand are central to this rating. A VA or private examination should measure the gap between each fingertip and the proximal transverse crease of the palm with the finger flexed as far as possible, and the gap between the thumb pad and the fingers during attempted opposition. Findings showing a gap of two inches or less on each digit support favorable ankylosis.
Exam notes should also specify which joints are ankylosed, whether one or both main joints of each digit are involved, and whether any joint is fixed in extension, full flexion, or with rotation or angulation of bone, since those findings would change how the digit is rated.
Records identifying which hand is affected matter because the rating differs between your major and minor hand. Statements from you or others describing how the stiffness limits your ability to grip, pinch, or perform daily tasks can help show the overall functional impact of the condition.
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.
