The Intracept Procedure: Relief for Vertebrogenic Low Back Pain
For years, the focus of chronic low back pain treatment has been on discs, nerves, and facet joints — and for good reason. But recent research has identified another significant pain source that's been largely overlooked: the vertebral endplates and the basivertebral nerve within the vertebra itself.
This is the target of the Intracept procedure — a minimally invasive, outpatient treatment that provides significant and durable relief for a specific and identifiable subset of chronic back pain patients.
What Is Vertebrogenic Pain?
Vertebrogenic pain originates from the vertebral endplates — the thin cartilaginous surfaces at the top and bottom of each vertebral body. The basivertebral nerve runs through the center of the vertebra and innervates these endplates.
When the endplates are damaged from disc degeneration, they show characteristic changes on MRI called Modic changes — bright signal changes in the vertebral body visible on specific MRI sequences. Studies suggest that Modic Type 1 or Type 2 changes are present in up to 35–40% of patients with chronic low back pain, representing a significant and specific pain generator.
How Intracept Works
Through a small transpedicular approach (entering through the bony projection on the back of the vertebra — the pedicle), a specialized radiofrequency probe is advanced to the center of the vertebral body where the basivertebral nerve resides. Radiofrequency energy is then delivered to permanently ablate the basivertebral nerve.
This is done under fluoroscopic guidance as an outpatient procedure. No fusion, no disc removal, no significant incision.
The Evidence
The INTRACEPT trial, published in the New England Journal of Medicine Evidence, is the landmark study. Results:
- 75% of treated patients achieved clinically meaningful improvement at 3 months
- Results maintained at 2-year follow-up — dramatically better than sham procedure
- Significant advantages over standard medical management
- No serious adverse events
Notably, unlike medial branch nerves (which regenerate after RFA), the basivertebral nerve appears to have limited regeneration capacity — making Intracept potentially more durable than typical radiofrequency ablation.
Am I a Candidate?
You may be a candidate for Intracept if:
- Your primary complaint is chronic low back pain (not leg pain)
- Your MRI shows Modic Type 1 or Type 2 changes in the vertebral body
- You've had 6+ months of pain despite conservative treatment
- You prefer to avoid surgery
If you don't know whether your MRI shows Modic changes, bring your MRI report and images to your consultation — we can review them together.
Coverage
Medicare has established coverage criteria for the Intracept procedure. Commercial insurance coverage varies and our office will verify your benefits.
