Service-connected sciatica frequently originates in the lumbar disc, where annular tears irritate the nerve root that travels into the leg. When fusion or repeat injections have not resolved the pain, intra-annular fibrin injection offers a regenerative option that targets the disc tear rather than removing tissue or joining vertebrae.
Key Takeaways
- Sciatica is a symptom; the underlying driver is most frequently a disc lesion compressing or irritating the nerve root.
- Veterans frequently develop service-connected sciatica from cumulative load, vehicle vibration, or trauma.
- Epidural steroid injections are not effective for chronic low back pain per AAFP systematic review.
- Intra-annular fibrin injection seals annular tears that drive nerve-root irritation in selected cases.
- Imaging review establishes whether sciatica originates from a tear, a herniation, stenosis, or another driver.

What is sciatica in plain language?
Sciatica is pain that travels along the sciatic nerve from the low back into the buttock and down the leg. It is a symptom, not a diagnosis. The most common driver is irritation or compression of the nerve root where it exits the spine — usually due to a disc bulge, herniation, or annular tear leaking inflammatory chemistry onto the nerve.
Because sciatica is downstream of the underlying lesion, treating the leg pain without addressing the disc rarely produces durable change. That is why patients can have repeat injections without lasting relief.
Why is sciatica common in the veteran population?
The cumulative loading of military service — rucks, body armor, parachuting, vehicle vibration, lifting in awkward positions — is hard on lumbar discs. Annular tears in the lower lumbar segments are common, and when those tears are at the posterolateral corner of the disc, they sit close to the exiting nerve root.
Veterans often present with leg-dominant pain, numbness, or weakness that has been treated as nerve pain in isolation. The imaging review at Valor focuses on what is happening at the disc level that explains the nerve symptom.
Why look beyond fusion when sciatica persists?
Fusion can be the right answer for unstable segments or severe disc-height collapse. For nerve-root irritation driven by a localized annular tear, fusion is a heavy intervention that does not always be necessary. Patients who have undergone fusion for radicular pain and continue to have leg symptoms commonly fall into the Failed Back Surgery Syndrome category.
When does regenerative treatment fit?
Regenerative treatment fits when imaging shows discrete annular tears as the pain generator, disc height is reasonably preserved, and conservative care has not resolved the symptom. The fibrin sealant addresses the tear directly. Outcomes data show meaningful pain-score reductions in published cohorts; individual outcomes vary, and a clinical evaluation determines fit for any specific veteran.
What does a candidacy evaluation include?
The Valor evaluation includes review of recent MRI imaging, a focused neurologic exam, history of conservative care, and review of any prior surgical or interventional records. The team looks for the pain generator — the tear, herniation, or other lesion explaining the nerve symptom. The output is a candidacy answer, not a sales pitch.
Clinical Note
The veterans we see with service-connected sciatica are almost always tired of being told their imaging “looks fine for their age.” A 50-year-old combat veteran’s imaging is not the same as a 50-year-old desk worker’s, and the threshold for tolerating disc-level findings is different too. Our clinical staff reads the imaging in the context of what the veteran’s life actually demands. When we find a tear that explains the nerve symptom, we say so. When we do not, we say that too — and we point the veteran toward the right next step rather than offering a procedure that will not help.
Frequently Asked Questions
Does the procedure address leg pain or just back pain?
Both are possible. When the leg pain comes from disc-level inflammation reaching the nerve root, sealing the tear can reduce the leg symptom along with the back symptom.
How is the procedure different from a steroid injection?
Steroid injections reduce inflammation around the nerve. The procedure delivers a fibrin sealant into the disc itself to seal the tear that is driving the inflammation.
What if my sciatica is bilateral?
Bilateral sciatica can come from central or multi-level pathology. The imaging review determines whether the procedure addresses the driver or whether a different intervention is more appropriate.
Is the procedure available to non-service-connected veterans?
Many enrolled veterans qualify for community-care even for non-service-connected conditions. Eligibility is determined by the VA on a case-by-case basis.
