Intracept Procedure for Chronic Low Back Pain: How It Works

If you have chronic low back pain that hasn’t improved after months of physical therapy, medication, and injections, the source may be inside the vertebrae themselves — not a disc or a joint. The Intracept procedure, also called basivertebral nerve ablation, is a minimally invasive treatment built for exactly that problem. This guide explains what it is, who it helps, and what recovery looks like.

What is the Intracept procedure?

The Intracept procedure is a minimally invasive treatment that targets the basivertebral nerve — a small nerve deep inside the vertebra that carries pain signals from worn vertebral endplates to the brain. Using radiofrequency energy, a pain physician heats and disables that nerve so it can no longer send the pain message. Because it works inside the bone rather than on a disc or joint, it addresses a specific kind of back pain that other treatments often miss.

What is vertebrogenic back pain?

Vertebrogenic back pain is chronic low back pain that comes from damage to the endplates — the thin layers of cartilage and bone where a disc meets the vertebra above and below it. When these endplates wear down or become inflamed, the basivertebral nerve inside the vertebra becomes irritated and sends a steady pain signal. This kind of pain is often felt as a deep, aching, midline ache in the lower back that gets worse with sitting, bending forward, or physical activity.

On an MRI, vertebrogenic pain is linked to specific changes at the endplates (known as Modic changes). Because the pain doesn’t come from a pinched nerve or a herniated disc, it can be missed for years — which is why a careful diagnosis matters.

How does basivertebral nerve ablation work?

Basivertebral nerve ablation works by using heat to interrupt the nerve that carries the pain signal. Guided by live X-ray imaging, the physician places a small probe through a tiny opening in the back and into the vertebra, then delivers radiofrequency energy to the basivertebral nerve. That energy disables the nerve so it stops relaying pain from the damaged endplates. The disc, bones, and surrounding structures are left intact — nothing is removed or fused.

Who is a candidate for the Intracept procedure?

The Intracept procedure is meant for people whose chronic low back pain has a vertebrogenic source and hasn’t improved with conservative care. In general, good candidates have:

• Low back pain lasting six months or longer
• Pain that hasn’t responded to physical therapy, medication, or injections
• MRI changes at the vertebral endplates consistent with vertebrogenic pain

At Empire Minimally Invasive Spine and Pain, that diagnosis is made carefully — because the treatment only helps when the pain truly comes from the endplates. You can learn more on our basivertebral nerve ablation treatment page.

What happens during the procedure?

The Intracept procedure is done in an outpatient setting and usually takes about an hour. You’re positioned face down, the area is numbed, and using X-ray guidance the physician creates one small opening to reach the vertebra. The radiofrequency probe treats the basivertebral nerve, and the small opening is closed with a bandage — no large incision and no stitches into muscle. Most people go home the same day.

Recovery and results

Recovery from the Intracept procedure is typically quick because nothing is fused or removed. Many people return to light activity within a few days and feel fully recovered within a couple of weeks. Pain relief may build gradually over the following weeks as the area settles.

Intracept vs. other radiofrequency treatments

Radiofrequency energy is used in more than one back-pain treatment, and it helps to know the difference. Radiofrequency ablation (RFA) for facet pain targets the small nerves around arthritic facet joints. The Intracept procedure targets a different nerve — the basivertebral nerve inside the vertebra — for pain coming from the endplates. They treat different sources, so the right one depends on where your pain actually originates. Injections such as an epidural steroid injection work differently again; our guide on epidural injection vs. radiofrequency ablation explains how those compare.

When should you see a specialist?

See a pain specialist if you’ve had low back pain for several months that hasn’t improved with therapy and medication, especially if it’s a deep, central ache that worsens with sitting or bending. A specialist can determine whether your pain is vertebrogenic and whether a targeted treatment like Intracept fits. Persistent pain deserves a precise diagnosis rather than an endless cycle of temporary fixes — and general back pain care is the starting point.

Frequently asked questions

Is the Intracept procedure the same as spinal fusion?

No. Spinal fusion permanently joins vertebrae together with hardware. The Intracept procedure doesn’t fuse or remove anything — it simply disables one small nerve inside the vertebra. Cleveland Clinic describes it as a minimally invasive alternative to open back surgery.

How long does relief from Intracept last?

For appropriate candidates, the relief is durable. Cleveland Clinic reports that many people have significant pain reduction that lasts five years or longer, because the treated basivertebral nerve does not regrow the way some other nerves do.

Is the Intracept procedure painful?

The procedure is done with anesthesia, so you shouldn’t feel pain during it. Afterward, some soreness at the treatment site is normal for a few days and usually settles quickly. Most people fully recover within one to two weeks.

How do I know if my back pain is vertebrogenic?

Vertebrogenic pain is usually a deep, central low back ache that worsens with sitting and bending and hasn’t responded to standard care. An MRI showing endplate (Modic) changes helps confirm it. A pain specialist puts the picture together before recommending treatment.

Can I have Intracept if I’ve already had back surgery?

Sometimes. Prior back surgery doesn’t automatically rule it out, but candidacy depends on your imaging and the source of your current pain. A specialist will review your history and MRI to decide whether it’s a good fit.
