Index Finger Ankylosis

DC 5225Musculoskeletal38 CFR 4.71a, DC 5225

Complete fusion of one or more joints of the index (pointer) finger, where the finger is permanently fixed with no remaining motion at the affected joint(s). This significantly impairs pinch grip, typing, and fine motor tasks. The VA rates index finger ankylosis based on whether it is favorable or unfavorable and whether it is on the dominant or non-dominant hand.

How the VA rates this condition

The VA rates this condition based on how much it affects your ability to work and carry out daily activities. The examiner will focus on the functional limitations your condition causes, not just the diagnosis itself.

Rating range

10% – 30%

Rating levels

Rating criteria are defined in 38 CFR 4.71a, DC 5225. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.

Rating Levels

You have unfavorable ankylosis of the index finger on your dominant hand, with the finger fused in a non-functional position. This severely impairs writing, using tools, and most hand activities.

What the VA looks for

Index finger fused in non-functional position (dominant hand)
Severe impairment of grip, pinch, and fine motor function
Major occupational disability documented
Inability to perform precision tasks with dominant hand

Common Pitfalls

⚠Not documenting dominant hand — ratings for unfavorable ankylosis differ between the major (dominant) and minor (non-dominant) hand.
⚠Not distinguishing favorable from unfavorable — favorable ankylosis means the finger is fused in a position that preserves some function. Unfavorable ankylosis means the finger is fixed in a position that interferes with overall hand function or the use of other fingers.
⚠Overlooking the impact on other fingers — if the ankylosed index finger interferes with the use of adjacent fingers, this should be documented as it may warrant a higher evaluation or separate ratings.
