Annular tears cause chronic low back pain through two mechanisms: direct stimulation of the densely innervated outer annulus and inflammatory chemistry leaking from the disc into surrounding tissue. The pain is real, structural, and persistent because the tear continues to generate it. Sealing the tear addresses both mechanisms.
Key Takeaways
- The annulus is densely innervated; tears cause direct pain.
- Inflammatory leakage from torn discs irritates surrounding tissue.
- Untreated tears continue generating pain over years.
- Sealing the tear addresses both mechanisms.
- Imaging confirms whether tears are the driver.

- Why do untreated tears persist?
- How does the fibrin procedure address both?
What is the first pain mechanism?
The first mechanism is direct nerve stimulation. The outer annulus contains pain-sensing nerve fibers in high density. A tear disrupts the structure and stimulates those fibers, producing localized back pain that is commonly positional and mechanical.
What is the second pain mechanism?
The second mechanism is inflammatory leakage. A torn disc releases inflammatory cytokines and other chemistry into the surrounding tissue. That chemistry irritates adjacent structures, including nerve roots, producing both back pain and downstream symptoms like sciatica.
Why do untreated tears persist?
The disc has limited blood supply, which slows intrinsic healing. Mechanical loads continue to stress the lesion. Without intervention to seal the tear or remove the load, the cycle of damage and irritation continues over years.
How does the fibrin procedure address both?
The fibrin procedure delivers a sealant into the tear, holding it closed and creating conditions for biologic healing. Sealing the tear stops both the direct mechanical stimulation and the inflammatory leakage that drove pain. The sealant scaffolds the body’s own repair.
Clinical Note
Patients with chronic low back pain sometimes hear that nothing is structurally wrong because the imaging report is brief. Our clinical staff reads the imaging in detail and looks specifically for annular tears, which are the most common driver of disc-related pain in this population. When we find the tear, the explanation for the persistent pain becomes concrete. The Valor team’s posture is to identify the source and make sure patients understand it before discussing treatment.
Frequently Asked Questions
Are annular tears visible on every MRI?
Tears are visible on most modern MRI sequences but not all. Imaging quality matters.
Can a small tear cause significant pain?
Yes. Tear size correlates loosely with pain; location and inflammation matter more.
Will the tear heal once sealed?
The fibrin scaffold supports tissue healing over weeks to months.
