Secondary Condition Claim · VASRD 5215
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Ankylosis of the Wrist (Major) when it develops after Ankylosis of Thumb and One or More Fingers.
Impaired thumb use can lead to poor wrist control.
Primary condition · VASRD 5233
Ankylosis of Thumb and One or More Fingers
Fusion or stiffness of the thumb and another finger limits ability to pinch, grip, or write.
Secondary condition · VASRD 5215
Ankylosis of the Wrist (Major)
A fused wrist joint with no ability to bend, often due to trauma or arthritis.
The VA rates Ankylosis of the Wrist (Major) the same way whether it's claimed directly or as secondary to Ankylosis of Thumb and One or More Fingers — severity of Ankylosis of the Wrist (Major) itself determines the percentage.
Example combined rating
20% Ankylosis of Thumb and One or More Fingers + 40% Ankylosis of the Wrist (Major) = 52%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 20% and 40% combine to 52%, not 60%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
