Secondary Condition Claim · VASRD 8520
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 Paralysis of the Sciatic Nerve when it develops after Amputation of Leg, with Defective Stump.
Nerve damage near the stump site
Primary condition · VASRD 5043
Amputation of Leg, with Defective Stump
Below-knee amputation where the stump cannot support a prosthetic effectively.
Secondary condition · VASRD 8520
Paralysis of the Sciatic Nerve
Damage to the sciatic nerve that causes leg weakness, pain, or paralysis.
The VA rates Paralysis of the Sciatic Nerve the same way whether it's claimed directly or as secondary to Amputation of Leg, with Defective Stump — severity of Paralysis of the Sciatic Nerve itself determines the percentage.
| Rating | Criteria |
|---|---|
| 80% | Foot hangs limp and can’t move below the knee due to nerve damage. |
| 60% | Severe weakness and pain in leg with visible muscle loss. |
| 40% | Leg weakness and numbness interfere with walking and standing. |
| 20% | Mild leg weakness or numbness from nerve damage. |
| 10% | Mild nerve issues like tingling or shooting leg pain. |
Example combined rating
60% Amputation of Leg, with Defective Stump + 40% Paralysis of the Sciatic Nerve = 76%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 60% and 40% combine to 76%, not 100%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
