Radiofrequency Lesioning

What is Radiofrequency Lesioning

Radiofrequency lesioning is a procedure that is performed to relieve pain. The procedure is often used for back, neck, or arm pain. Radiofrequency lesioning involves the use of a machine that creates radio waves to make heat.

During the procedure, the heat is applied to the nerve that carries the pain signal. The heat damages the nerve and interferes with the pain signal. Pain relief usually starts about 2 weeks after the procedure and lasts for 6 months to 1 year.

Tell a health care provider about:

  • Any allergies you have.
  • All medicines you are taking, including vitamins, herbs, eye drops, creams, and over-the-counter medicines.
  • Any problems you or family members have had with anesthetic medicines.
  • Any blood disorders you have.
  • Any surgeries you have had.
  • Any medical conditions you have.
  • Whether you are pregnant or may be pregnant.

What are the risks?

Generally, this is a safe procedure. However, problems may occur, including:

  • Pain or soreness at the injection site.
  • Infection at the injection site.
  • Damage to nerves or blood vessels.

What happens before the procedure?

  • Ask your health care provider about:
    • Changing or stopping your regular medicines. This is especially important if you are taking diabetes medicines or blood thinners.
    • Taking medicines such as aspirin and ibuprofen. These medicines can thin your blood. Do not take these medicines before your procedure if your health care provider instructs you not to.
  • Follow instructions from your health care provider about eating or drinking restrictions.
  • Plan to have someone take you home after the procedure.
  • If you go home right after the procedure, plan to have someone with you for 24 hours.

What happens during the procedure?

  • You will be given one or more of the following:
    • A medicine to help you relax (sedative).
    • A medicine to numb the area (local anesthetic).
  • You will be awake during the procedure. You will need to be able to talk with the health care provider during the procedure.
  • With the help of a type of X-ray (fluoroscopy), the health care provider will insert a radiofrequency needle into the area to be treated.
  • Next, a wire that carries the radio waves (electrode) will be put through the radiofrequency needle. An electrical pulse will be sent through the electrode to verify the correct nerve. You will feel a tingling sensation, and you may have muscle twitching.
  • Then, the tissue that is around the needle tip will be heated by an electric current that is passed using the radiofrequency machine. This will numb the nerves.
  • A bandage (dressing) will be put on the insertion area after the procedure is done.

The procedure may vary among health care providers and hospitals.

What happens after the procedure?

  • Your blood pressure, heart rate, breathing rate, and blood oxygen level will be monitored often until the medicines you were given have worn off.
  • Return to your normal activities as directed by your health care provider.
