Radiofrequency Ablation (RFA)

Radiofrequency ablation (RFA) is a minimally invasive procedure used to treat chronic pain by targeting specific nerves.

During this treatment, heat generated by radio waves is applied to small nerve areas to interrupt pain signals before they reach the brain.

RFA is commonly used for back, neck, and joint pain, especially when other treatments like medications or injections have not provided lasting relief.

What Conditions Does This Treatment Help?

Radiofrequency ablation is commonly used to treat:

How Does Radiofrequency Ablation Work?

Pain is often caused by nerves continuously sending signals to the brain.
  • A thin needle is placed near the targeted nerve
  • An electrode delivers radiofrequency energy (heat)
  • The heat creates a small lesion on the nerve
  • This blocks the nerve’s ability to transmit pain signals
This does not damage surrounding tissues and focuses only on the pain-carrying nerve fibers.

What to Expect During the Procedure

Before the Procedure
  • A medial branch block or diagnostic injection is usually performed first
  • If significant relief is achieved, RFA is recommended
During the Procedure
  • Performed under fluoroscopy (X-ray guidance)
  • Local anesthesia with or without sedation
  • A needle is placed near the nerve
  • Heat is applied through an electrode
  • Procedure takes 15–60 minutes
After the Procedure
  • Same-day discharge
  • Mild soreness for a few days
  • Return to normal activity within 24–48 hours

Benefits of Radiofrequency Ablation

✔ Minimally invasive, no surgery required
✔ Provides longer-lasting relief than injections
✔ Reduces need for pain medications
✔ Improves mobility and function
✔ Quick recovery time

Pain relief can last 6–12 months or longer, and the procedure can be repeated if needed.

Who Is a Good Candidate?

You may be a candidate if you:

  • Have chronic pain lasting 3–6 months or more
  • Have pain coming from facet or joint-related nerves
  • Experienced relief from a diagnostic nerve block
  • Have not improved with medications or therapy

👉 RFA works best when the pain source is clearly identified

Risks & Side Effects

Radiofrequency ablation is generally safe, but possible risks include:
  • Temporary soreness or burning sensation
  • Numbness at the treatment site
  • Infection or bleeding (rare)
  • Nerve injury (very rare)
Some patients may experience temporary discomfort before improvement begins.

When Is This Treatment Recommended?

Radiofrequency ablation is typically recommended when:
  • Conservative treatments have failed
  • Diagnostic injections confirm the pain source
  • Pain is chronic and affecting daily life
  • Patients want to avoid surgery
👉 It is positioned as a next step after injections and before surgery

Recovery & Results

  • Mild soreness may last a few days
  • Pain relief may begin within 1–3 weeks
  • Relief typically lasts months to over a year
  • Nerves may regenerate over time, and the procedure can be repeated
Many patients experience significant improvement in daily activities and quality of life.

FAQs

Most patients feel minimal discomfort due to local anesthesia and sedation.
Relief typically lasts 6–12 months or longer.
Yes, nerves can regenerate over time, which may require repeat treatment.
RFA generally provides longer-lasting relief compared to injections.

FAQs

RFA uses a heated electrode at 80°C for about 90 seconds to disrupt the nerve’s ability to send pain signals, resulting in reduced pain for the patient.

A patient must complete two successful Medial Branch Block (MBB) trials to confirm that the correct nerve is responsible for their pain.

RFA is typically used for Axial Low Back Pain caused by facet-mediated pain secondary to osteoarthritis of the spine.

RFA can help treat low back pain, neck pain, knee pain, shoulder pain, cancer pain, arthritis, herniated discs, migraine headaches, whiplash CAD, and post-laminectomy syndrome.
