What is a Radiofrequency Ablation?

Radiofrequency ablation (RFA), also known as radiofrequency neurotomy or radiofrequency denervation, is a minimally invasive procedure used to reduce or eliminate pain arising from certain nerves. It involves the use of radiofrequency energy to heat and disrupt the function of targeted nerve fibers. RFA is commonly used to treat chronic pain conditions, particularly those associated with the spine and joints.


During a radiofrequency ablation procedure:

  1. Local Anesthesia: The area around the targeted nerve is numbed using a local anesthetic.
  2. Electrodes Placement: Needle-like electrodes are inserted through the skin and positioned near the targeted nerve using imaging guidance (such as fluoroscopy).
  3. Nerve Stimulation: Mild electrical stimulation is applied through the electrodes to identify the exact location of the target nerve and confirm its relationship to the patient’s pain.
  4. Radiofrequency Ablation: Once the target nerve is confirmed, radiofrequency energy is delivered through the electrodes to heat the nerve tissue. This generates heat and causes the nerve to stop transmitting pain signals.
  5. Post-Procedure: After the procedure, the electrodes are removed, and the patient is monitored for a short time before being discharged.


Radiofrequency ablation is used to treat various chronic pain conditions, including:

  • Facet Joint Pain: RFA can be used to treat pain originating from the facet joints in the spine.
  • Sacroiliac Joint Pain: It can alleviate pain from the sacroiliac joints that connect the spine to the pelvis.
  • Nerve Pain: RFA can target nerves responsible for transmitting pain signals, such as the medial branch nerves or the genicular nerves in the knee.
  • Trigeminal Neuralgia: A condition causing facial pain, RFA can be used to target the trigeminal nerve.
  • Occipital Neuralgia: Pain at the back of the head can be treated with RFA targeting the occipital nerves.


  • Pain Relief: RFA can provide effective and long-lasting pain relief for many patients, allowing them to resume normal activities.
  • Minimally Invasive: RFA is performed using small incisions and local anesthesia, reducing the risk of complications and minimizing recovery time.
  • Non-Destructive: Unlike surgical procedures, RFA does not remove tissue; it only disrupts nerve conduction.


  • Temporary Relief: While RFA can provide significant pain relief, the effects are not always permanent and may require repeat procedures over time.
  • Response Varies: Individual responses to RFA can vary, and not all patients experience the same degree of relief.
  • Risks: Potential risks include infection, bleeding, nerve injury, and temporary discomfort at the procedure site.

Before undergoing radiofrequency ablation, it’s important to have a thorough discussion with a healthcare provider who specializes in pain management. They can assess your condition, discuss potential benefits and risks, and determine if RFA is an appropriate treatment option for your specific pain condition.
