Radiofrequency Ablation

What is Radiofrequency Ablation?

Radiofrequency ablation (RFA) is a minimally invasive outpatient procedure used to treat chronic neck and low back pain caused by arthritic facet joints. It works by applying carefully controlled heat to small sensory nerves—called the medial branches—that carry pain signals from the joints to the brain.

By stopping these signals, RFA can provide long-lasting relief, reduce reliance on medications, and help patients return to normal activity.

Why Facet Joints Cause Pain

The facet joints are small stabilizing joints along the spine that allow bending and twisting. Over time, they can become arthritic, inflamed, or injured—this is called facet arthropathy.

  • Cervical facet pain: aching, stiffness, or headaches at the base of the skull, worse with turning or looking up.
  • Lumbar facet pain: aching in the low back, often worse with standing, twisting, or extension.

Unlike sciatica or a herniated disc, facet joint pain usually does not radiate below the knee or elbow, but it can still be severe and disabling.

How RFA Works

  1. Diagnostic confirmation: Before RFA, patients receive medial branch blocks—temporary numbing injections around the facet nerves. If these provide short-term relief, the facet joints are confirmed as the pain source.
  2. Precise targeting: During RFA, a thin probe is placed next to the medial branch nerves using live X-ray guidance.
  3. Thermal treatment: Controlled heat (about 80°C) is applied for 60–90 seconds, creating a small lesion that stops the nerve from transmitting pain.
  4. Function preserved: These nerves only carry pain sensation—they do not control muscles or movement—so strength and mobility are unaffected.

Benefits of Cervical and Lumbar RFA

  • Relief lasting 6–12 months or longer in most patients
  • Improved mobility, sleep, and daily function
  • Reduced dependence on medications, including opioids
  • Outpatient procedure with minimal downtime (return to activities in 1–2 days)

Is RFA Right for You?

Radiofrequency ablation is considered when patients have:

  • Chronic neck or low back pain
  • Inadequate relief from non-surgical options
  • Positive response to two diagnostic nerve blocks

It is a safe, effective, outpatient procedure that can offer long-lasting relief, enabling you to get back to the things you love.

What to Expect

  • Performed in our office-based lab (OBL) under local anesthesia, with light sedation if needed
  • Mild soreness at the injection site is common for a few days
  • Pain relief typically begins within 1–3 weeks
  • Results usually last 6–12 months; nerves may regrow, but the procedure can be repeated if pain returns

Patient FAQ

What exactly is facet joint pain?
Facet joints are small joints in your spine that can develop arthritis and inflammation. This causes aching in the neck or low back, often worse with extension or twisting.
How do I know if my pain is coming from the facet joints?
A diagnostic medial branch block—a numbing injection around the facet nerves—is the gold standard. If pain improves temporarily, the facet joints are confirmed as the source.
What happens during the RFA procedure?
After numbing the skin, a thin probe is placed next to the medial branch nerves under X-ray. Heat is applied for 60–90 seconds to stop the nerve from transmitting pain. You go home the same day.
Will RFA affect my strength or movement?
No. The targeted nerves only transmit pain sensation and do not control muscles.
How soon will I feel relief?
Some patients notice improvement within days, but full benefit may take up 4 weeks
How long does relief last?
Most patients experience 6–12 months of relief, sometimes longer. Repeat RFA can be performed safely if pain returns.
What are the risks of RFA?
Risks are very low. Temporary soreness, bruising, or mild numbness at the injection site are possible risks. Rarely, infection or bleeding may occur.
How does RFA compare to injections or medications?
Facet joint injections usually provide short-term relief, while RFA can last many months to 1-2 years. RFA avoids the risks of chronic medication use including dependence/addiction and is less invasive than surgery.
Is RFA covered by insurance?
Yes. Medicare and most major insurance plans cover RFA if criteria are met which includes two prior positive diagnostic nerve blocks confirming the source of pain.
