Paralysis of the Sciatic Nerve Secondary to Hip Replacement (Prosthetic)
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 Hip Replacement (Prosthetic).
Why Paralysis of the Sciatic Nerve Is Linked to Hip Replacement (Prosthetic)
Can result from surgical irritation or altered biomechanics
Primary condition · VASRD 5054
Hip Replacement (Prosthetic)
Your hip joint has been replaced with a prosthesis, or resurfaced, and VA evaluates the result under diagnostic code 5054. The code covers both procedures, but its 30 percent minimum is for a total replacement only.
Secondary condition · VASRD 8520
Paralysis of the Sciatic Nerve
Damage to the sciatic nerve that causes leg weakness, pain, or paralysis.
Paralysis of the Sciatic Nerve VA Rating Tiers
The VA rates Paralysis of the Sciatic Nerve the same way whether it's claimed directly or as secondary to Hip Replacement (Prosthetic) — 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
70% Hip Replacement (Prosthetic) + 40% Paralysis of the Sciatic Nerve = 82%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 70% and 40% combine to 82%, not 110%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.

Using the official combined-ratings formula (38 CFR 4.25): a 70% rating for Hip Replacement (Prosthetic) combined with a 40% rating for Paralysis of the Sciatic Nerve (example figures) produces a combined rating of 82%, not 110%. Approving Paralysis of the Sciatic Nerve as secondar…
- What evidence do I need to service-connect Paralysis of the Sciatic Nerve as secondary to Hip Replacement (Prosthetic)?
- Strong evidence for the underlying Paralysis of the Sciatic Nerve diagnosis includes: EMG or nerve conduction study showing sciatic involvement; Neurologist report describing motor/sensory deficits; Functional assessment showing gait or mobility loss. For the secondary link itself, a nexus letter from a treating provi…
