In short — Basivertebral nerve ablation is a minimally invasive, image-guided procedure that treats a specific nerve inside certain vertebrae, and may help selected patients whose chronic low back pain is linked to particular MRI findings called Modic changes. It targets a different pain generator than facet-joint radiofrequency ablation and is not appropriate for every type of back pain.
A patient in Mandarin has had midline low back pain for two years. Physical therapy helped a little. An epidural injection helped for a few weeks and then wore off. Her MRI report mentions "Type 2 Modic changes" at two levels, a phrase her prior doctors never fully explained.
A patient in Orange Park had radiofrequency ablation of his facet joints last year for arthritis-related back pain. It worked well — for the facet pain. But he still has a separate, deeper ache along the midline of his low back that the facet procedure never touched.
Both of these situations point toward the same idea: not all chronic low back pain comes from the same structure, and a treatment aimed at the wrong pain generator will not help, no matter how well it is performed. For some patients, particularly those with specific MRI changes, the vertebral endplate itself — and the nerve that serves it — may be the source worth investigating.
What is vertebrogenic back pain?
Vertebrogenic back pain refers to chronic low back pain believed to originate from the vertebral endplate, the thin bony surface that sits between an intervertebral disc and the vertebra above or below it. When an endplate is damaged or inflamed, it can become a persistent source of pain that is distinct from a disc bulge, a facet joint, or a compressed nerve root.
The clue is usually on MRI, in the form of Modic changes — specific signal patterns in the bone marrow adjacent to the endplate. Type 1 Modic changes reflect more active inflammation and edema; Type 2 reflects more fatty replacement. Not every patient with Modic changes has significant pain from them, and not every case of chronic low back pain shows Modic changes at all, which is why imaging findings are interpreted alongside the pain pattern and exam rather than by themselves.
A common point of confusion: isn't this the same as facet radiofrequency ablation?
It is easy to assume that any procedure using radiofrequency energy on the spine is interchangeable with any other, but the target nerve and the pain generator are different. Facet-joint radiofrequency ablation treats the medial branch nerves that sit outside the vertebral body and carry pain signals from the facet joints connecting adjacent vertebrae.
Basivertebral nerve ablation instead treats a nerve located inside the vertebral body itself, which carries pain signals from a damaged endplate. A patient can have facet-related pain, vertebrogenic pain, or both at the same time, which is one reason a careful history, exam, and MRI review matter before recommending either procedure.
How the procedure works
Basivertebral nerve ablation is an outpatient, image-guided procedure performed under fluoroscopy (a form of real-time X-ray) with local anesthesia and typically some sedation. A thin, curved probe is introduced through the pedicle — a bony bridge at the back of the vertebra — and advanced into the vertebral body to reach the location of the basivertebral nerve. Radiofrequency energy is then delivered for a set period to treat the nerve, after which the probe is removed.
The device used for this procedure (marketed under the brand name Intracept) carries FDA clearance specifically for the L3 through S1 vertebral levels, in adults with chronic low back pain of at least six months' duration, Modic Type 1 or Type 2 changes on MRI at the treated level or levels, and no adequate response to at least six months of conservative care such as physical therapy, activity modification, and medication.
What this means for patients
Basivertebral nerve ablation is not a first-line treatment and is not a fit for every kind of back pain. It is intended for a specific subset of patients: those with predominantly midline, non-radiating low back pain, the corresponding Modic changes on MRI, and a history of conservative treatment that has not provided enough relief. Patients whose pain is primarily radiating into a leg, or who have significant facet or sacroiliac joint involvement instead, are more likely to be candidates for a different approach.
A physician evaluation that reviews imaging alongside the pattern and duration of pain, and what has already been tried, is what determines whether this procedure is a reasonable next step — not the presence of Modic changes on a radiology report alone.
What the evidence shows
Basivertebral nerve ablation has been studied in a randomized, sham-controlled trial as well as in longer-term follow-up studies extending out to five years. Pooled analyses from these studies have reported that roughly two-thirds of appropriately selected, treated patients experienced meaningful, sustained improvement in pain and function at one year. As with any procedure, individual results vary, some patients experience limited or no benefit, and most of the published research to date has been funded by the device's manufacturer, which is worth knowing when weighing the evidence.
Risks and recovery
Reported risks include temporary soreness or leg pain, nerve irritation, bleeding, infection, incomplete pain relief, and, rarely, a vertebral fracture. As with any spine procedure, an individualized discussion of risks, benefits, and alternatives should happen before scheduling.
Recovery from this outpatient procedure is typically brief. Most patients are advised to limit heavy lifting and vigorous activity for a short period afterward, with a gradual return to normal activity over days to a couple of weeks, following the specific instructions given by the treating physician.
Seek prompt medical attention for fever, spreading redness or drainage at the procedure site, new or worsening leg weakness or numbness, or loss of bladder or bowel control — these can be signs of a serious complication that should not wait for a scheduled follow-up.

The bottom line
Not all chronic low back pain shares the same source, and a procedure aimed at the wrong pain generator will not help, however well it is performed. For selected patients with midline low back pain and Modic changes on MRI who have not improved with conservative care, basivertebral nerve ablation targets a specific, different nerve than facet-joint radiofrequency ablation and may be worth discussing.
An MRI mentioning Modic changes is a detail worth asking about, not a phrase to move past — it may point toward a treatable pain generator that a standard treatment ladder has not yet addressed.
Frequently Asked Questions
What is vertebrogenic back pain?
Vertebrogenic back pain is chronic low back pain believed to come from the vertebral endplate — the bony surface between a disc and the vertebra above or below it — rather than from a disc, facet joint, or nerve root. On MRI, it is associated with Type 1 or Type 2 Modic changes, which are specific signal patterns at the endplate.
What is basivertebral nerve ablation?
Basivertebral nerve ablation is a minimally invasive, image-guided procedure that uses radiofrequency energy delivered through a probe placed inside the vertebral body to treat the basivertebral nerve, which carries pain signals from a damaged endplate. The device used for this procedure is FDA-cleared for use at the L3 through S1 vertebrae in adults with at least six months of chronic low back pain and Modic Type 1 or Type 2 changes who have not responded to at least six months of conservative care.
How is this different from radiofrequency ablation for facet joint pain?
Facet-joint radiofrequency ablation targets the medial branch nerves outside the vertebral body that carry pain from the facet joints connecting adjacent vertebrae. Basivertebral nerve ablation targets a different nerve located inside the vertebral body itself, addressing pain from the endplate rather than the facet joint. The two procedures treat different suspected pain generators and are not interchangeable.
Who may be a candidate for basivertebral nerve ablation?
Candidates generally have chronic low back pain lasting six months or longer, midline pain that is not primarily radiating into a leg, MRI showing Modic Type 1 or Type 2 changes at one or more levels between L3 and S1, and no meaningful improvement from at least six months of conservative treatment such as physical therapy and medication. A physician evaluation, including imaging review, determines candidacy.
What does the evidence show about how well it works?
A randomized, sham-controlled trial and subsequent long-term follow-up studies have reported sustained improvement in pain and function for many treated patients through five years, with published pooled analyses reporting that roughly two-thirds of treated patients achieved meaningful pain reduction at one year. As with any procedure, results vary by patient, and it is not effective for everyone.
What are the risks and what does recovery involve?
Reported risks include temporary soreness or leg pain, nerve irritation, bleeding, infection, incomplete pain relief, and, rarely, a vertebral fracture. Recovery is typically brief for this outpatient procedure, with most patients easing back into normal activity over days to a couple of weeks, following the specific instructions given by the treating physician. Seek prompt medical attention for fever, spreading redness or drainage at the procedure site, new or worsening leg weakness or numbness, or loss of bladder or bowel control.
