Basivertebral Nerve Ablation for Chronic Low Back Pain

Not every back pain is a disc. Not every back pain is a facet. And a lot of patients with persistent, deep, midline low back pain have been told their problem is “nonspecific” — which usually means nobody has figured out where the pain is actually coming from.

Basivertebral nerve ablation targets a pain generator that most spine surgeons don’t talk about: the vertebral body itself. Inside the hard shell of each vertebra, there’s a network of nerves called the basivertebral nerve complex. For a long time, we thought these nerves were just maintenance workers — trophic nerves responsible for regulating bone density. It turns out they can carry pain signals. When the protective endplate of the disc wears down, the bone underneath gets inflamed. That inflammation irritates the basivertebral nerve, sending a deep, hard-to-localize ache to the brain.

Patients describe it perfectly: “bone-deep” pain. It doesn’t follow the usual rules. It doesn’t clearly get worse with extension the way facet pain does. It doesn’t radiate into the leg the way a compressed nerve does. It just sits there in the low back, often worse with sitting and flexion, and it’s resistant to the standard treatments — because those treatments are aimed at the wrong target.

Why standard treatments miss it

This is a pain generator that lives inside bone. You can’t massage a bone. An epidural injection sits outside the bone. Physical therapy strengthens muscles around the spine but doesn’t address inflammation inside a vertebral body. Facet injections and nerve blocks target structures behind the spine, not inside it. This is why patients with vertebrogenic pain cycle through PT, injections, and frustration without getting better. The treatments aren’t failing — they’re aimed at the wrong address.

The MRI clue

The key diagnostic finding is something called Modic changes on MRI. These are signal changes within the vertebral body endplates that most radiologists report but many clinicians gloss over.

Type 1 Modic changes are the ones that matter most. The bone marrow looks bright on certain MRI sequences, representing active inflammation and edema inside the bone. This is the painful phase — the basivertebral nerve is being irritated by an inflammatory process in the marrow itself.

Type 2 Modic changes represent the burned-out phase, where the marrow has converted to fat and the acute inflammation has settled. These are generally less painful.

When I see a patient with deep, midline low back pain, no radiculopathy, no clear surgical target, and Type 1 Modic changes at one or two levels — that’s a pattern. It’s not “nonspecific low back pain.” It’s vertebrogenic pain, and it has a specific treatment.

Physician demonstrating spine model to explain basivertebral nerve ablation procedure for chronic low back pain treatment — Basivertebral nerve ablation is a one-time outpatient procedure that eliminates pain signals without altering spinal structure.

How basivertebral nerve ablation works

The procedure is straightforward in concept. Under fluoroscopic (X-ray) guidance, a specialized probe is threaded through the pedicle of the vertebra into the vertebral body, navigating to the trunk of the basivertebral nerve near the midline of the bone. Radiofrequency energy is then delivered through the probe, heating the nerve and ablating it — permanently interrupting its ability to transmit pain signals.

It doesn’t fix the disc. It doesn’t fuse the bone. It doesn’t change the structure of the spine at all. What it does is cut the telephone line that’s sending the pain signal from the inflamed bone to the brain.

The procedure is performed as an outpatient surgery. Patients go home the same day. There’s no hardware left behind, no implant, no device to maintain. The ablation is a one-time procedure.

Since I have no formal medical training, I would like to provide you with my layman’s point of view of my case and the incredible journey I undertook. In early January of 2015 I developed a serious problem in my lower back and spine, which caused excruciating pain to the point where I was rendered incapable of basic normal function and activities. To give you a perception of the level of pain, I likened it to childbirth, the only difference for me is that with childbirth it would cease with the birth of the baby, and this pain was continuous. In retrospect there were signs and symptoms for…

Who is a candidate

The candidacy criteria are specific, and that’s actually one of the strengths of this procedure — when the patient fits the pattern, the results are reliable.

Good candidates typically have:

Chronic low back pain lasting at least 6 months
Pain that is primarily midline and axial — centered in the low back, not radiating into the legs
Pain that is worse with sitting and flexion loading
No radiculopathy (no leg pain, numbness, or weakness from a compressed nerve)
No clear surgical target — meaning the MRI doesn’t show a herniated disc or stenosis that explains the pain
Modic type 1 or type 2 changes on MRI at one or two lumbar levels
Failure of conservative treatments including physical therapy, medications, and injections

This procedure is not for everyone with back pain. It’s for a specific subset of patients whose pain originates from inside the vertebral body. The Modic changes on MRI are the essential diagnostic clue. Without them, the procedure doesn’t apply.

What the data shows

Basivertebral nerve ablation is supported by randomized controlled trial data showing durable pain relief. The SMART trial demonstrated statistically significant and clinically meaningful reductions in pain and disability compared to a sham (placebo) procedure — and those results held at 5-year follow-up. This is important because many pain procedures show short-term improvement that fades. The durability of the BVNA data is one of the reasons I’ve added it to my practice.

Why this matters

I performed a basivertebral nerve ablation recently and it made me think how often vertebrogenic pain gets written off in the average spine surgeon’s office. The patient had the classic presentation — deep midline pain, worse with sitting and flexion, no radiculopathy, no clear surgical target. The kind of patient who gets labeled “nonspecific low back pain” and sent through the usual cycle without anyone asking: what if the pain is coming from inside the bone?

That bright signal on MRI inside the vertebral body isn’t just a radiological curiosity. It’s active inflammation, and the basivertebral nerve carries that signal. Once you learn to recognize the pattern, you start seeing it everywhere. A lot of patients who’ve been told they’re “non-operative” may actually have a treatable pain generator that everyone has been looking past.

Recovery

Recovery is quick. Most patients are back to normal activity within a few days. There are no activity restrictions beyond common sense in the first week. There’s no brace, no physical therapy protocol, and no device to manage. Some patients notice improvement within weeks; for others, it takes up to 3 months for the full effect as the inflammatory process in the bone settles after the nerve is ablated.

Frequently Asked Questions

What is vertebrogenic pain?

Vertebrogenic pain is low back pain that originates from the vertebral body itself — specifically from irritation of the basivertebral nerve by inflammation within the bone. It’s distinct from disc pain, facet pain, and nerve compression pain. Patients typically describe a deep, midline ache that’s worse with sitting and doesn’t radiate into the legs. It’s identified on MRI by Modic changes within the vertebral endplates.

What are Modic changes?

Modic changes are signal abnormalities within the vertebral body endplates seen on MRI. Type 1 changes indicate active inflammation and edema inside the bone — this is the phase most associated with pain. Type 2 changes indicate the bone marrow has converted to fat, representing a more chronic, less inflammatory phase. Your radiologist reports these findings, but they’re often overlooked as a potential pain source.

Is basivertebral nerve ablation the same as radiofrequency ablation of the facet nerves?

No. Facet radiofrequency ablation targets the medial branch nerve outside the spine to treat facet joint pain. Basivertebral nerve ablation targets the nerve inside the vertebral body to treat pain originating from the bone itself. They treat completely different pain generators. Interestingly, the medial branch nerve targeted by facet ablation is the same nerve that controls the multifidus muscle — so facet ablation can potentially weaken spinal stability. BVNA doesn’t carry that risk because the basivertebral nerve has no motor function.

How long does the pain relief last?

The SMART clinical trial showed durable pain relief maintained at 5-year follow-up. Because the nerve is permanently ablated, the effect is expected to be long-lasting. The nerve does not typically regenerate in a clinically significant way.

Is this an outpatient procedure?

Yes. The procedure is performed under fluoroscopic guidance, typically under general anesthesia or heavy sedation. Patients go home the same day. There is no implant and no hardware.

Does insurance cover basivertebral nerve ablation?

Coverage is expanding but varies by carrier. The procedure has a specific CPT code and is FDA-cleared. Many commercial insurers and Medicare now cover it for patients who meet the clinical criteria. My office handles prior authorization and can advise you on your specific coverage before scheduling.

Can BVNA be done at the same time as other spine procedures?

In certain cases, yes. If a patient has both a structural problem (like stenosis requiring decompression) and Modic changes suggesting vertebrogenic pain at the same or adjacent level, it may make sense to address both in one session. This is a case-by-case decision based on imaging and clinical presentation.

How do I know if my back pain is vertebrogenic?

The pattern is: deep midline low back pain, worse with sitting and flexion, no leg symptoms, no clear surgical target on MRI, and Modic type 1 or 2 changes in the vertebral endplates. If this sounds like your situation, bring your MRI to a consultation and we’ll review it together.
