Basivertebral Nerve Ablation
A minimally invasive, implant-free treatment for chronic vertebrogenic low back pain
What is vertebrogenic pain?
The vertebral endplates are thin layers of cartilage and bone between each vertebra and its neighboring disc. When they are damaged or degenerate, pain signals travel from the endplates through the basivertebral nerve, which runs inside the vertebra itself.
This vertebrogenic pain is different from pain caused by a herniated disc or a strained muscle. It typically causes chronic pain in the center of the low back, and it can be identified on MRI by characteristic endplate changes known as Modic type 1 or 2 changes.
How it works
-
Access
Under X-ray guidance, a small access cannula is advanced just inside the back wall of the vertebral body.
-
Navigation
A curved introducer is guided through the cannula toward the center of the vertebra, where the basivertebral nerve branches.
-
Probe placement
A radiofrequency probe is positioned precisely at the nerve.
-
Ablation
Radiofrequency energy creates a controlled thermal lesion of the nerve, interrupting pain signals from the damaged endplates.
What to expect
Before your procedure
Your physician confirms the diagnosis with your history, exam, and MRI. Our team will review your medications, including blood thinners, and give you specific instructions.
During your procedure
BVNA is an outpatient procedure performed through a small incision with imaging guidance, typically with local anesthetic and sedation. No implant is left behind.
After your procedure
You'll be monitored briefly, then go home the same day. Soreness at the treatment site is common for a few days, and most patients notice improvement over the following weeks.
Is basivertebral nerve ablation right for you?
BVNA may be an option if:
- You have had chronic low back pain for at least 6 months
- Your pain hasn't improved with at least 6 months of conservative care, such as physical therapy and medications
- Your MRI shows Modic type 1 or 2 endplate changes in the lower lumbar spine
Our physicians will review your symptoms, exam, and imaging to determine whether this treatment is a good fit for you.
Risks
Risks are uncommon but include soreness at the treatment site, bleeding, infection, nerve injury, and the possibility that your pain is not fully relieved. Your physician will review the risks with you before your procedure. Individual results vary.
