Secondary Condition Claim · VASRD 8528

Common Peroneal Nerve Paralysis Secondary to Posterior Tibial Nerve Paralysis

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 Common Peroneal Nerve Paralysis when it develops after Posterior Tibial Nerve Paralysis.

Why Common Peroneal Nerve Paralysis Is Linked to Posterior Tibial Nerve Paralysis

Loss of nerve control

Primary condition · VASRD 8524

Posterior Tibial Nerve Paralysis

The posterior tibial nerve runs down the back of the calf and controls movement and sensation in the foot and toes. Damage to this nerve can cause numbness, tingling, weakness, or in severe cases the foot becoming fixed in a downward (plantar flexed) position, and it's most often linked to a specific leg injury or surgery.

Secondary condition · VASRD 8528

Common Peroneal Nerve Paralysis

Paralysis or weakness in the lower leg affecting foot lift (foot drop).

Common Peroneal Nerve Paralysis VA Rating Tiers

The VA rates Common Peroneal Nerve Paralysis the same way whether it's claimed directly or as secondary to Posterior Tibial Nerve Paralysis — severity of Common Peroneal Nerve Paralysis itself determines the percentage.

RatingCriteria
40%Foot drop, cannot lift foot
30%Weak lift, major mobility issues
20%Some weakness, altered gait
10%Minor weakness or numbness

Example combined rating

20% Posterior Tibial Nerve Paralysis + 30% Common Peroneal Nerve Paralysis = 44%

The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 20% and 30% combine to 44%, not 50%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.

Evidence for a Common Peroneal Nerve Paralysis Secondary Claim
