Ankylosis of Thumb VA Disability Rating

VA Rating Tiers

How the VA Evaluates Ankylosis of Thumb

DC 5224 has exactly two rating rows - 'Unfavorable' at 20 percent and 'Favorable' at 10 percent - and the major (dominant) and minor (non-dominant) columns carry identical values, so hand dominance does not change the evaluation here. What has to be established is that the thumb is ankylosed and what position it is fixed in. The code's note directs two further considerations: 'Also consider whether evaluation as amputation is warranted and whether an additional evaluation is warranted for resulting limitation of motion of other digits or interference with overall function of the hand.' A thumb that still moves but cannot reach the fingers is not rated here - that is DC 5228, limitation of motion of the thumb.
