Radiofrequency neurotomy

Updated: 01-24-2012

Definition

Radiofrequency neurotomy is a procedure to reduce back and neck pain. It uses heat generated by radio waves to damage specific nerves and temporarily interfere with their ability to transmit pain signals.

In radiofrequency neurotomy, the radio waves are delivered to the targeted nerves via needles inserted through the skin above your spine. Imaging scans are used during radiofrequency neurotomy to help the doctor position the needles precisely.

Radiofrequency neurotomy works better in some people than in others. Tests may be required to determine if the nerves commonly targeted by radiofrequency neurotomy are the same nerves responsible for your pain.

Why it's done

Radiofrequency neurotomy is most commonly performed by doctors specializing in the treatment of pain. The goal is to temporarily reduce chronic pain in the back or neck that hasn't been adequately relieved by other means, such as medications or physical therapy.

  • Paralysis
  • Bowel and bladder incontinence

How you prepare

To determine if you're a good candidate for radiofrequency neurotomy, your doctor may perform a test to see if the nerves commonly targeted by the procedure are the same nerves responsible for your pain.

This diagnostic test involves injecting a small amount of numbing medication into the precise spots where the radiofrequency needles will go. If your pain significantly lessens, radiofrequency treatment at those spots may help you.

Prior to the actual radiofrequency neurotomy procedure, you should:

  • Tell your doctor if you're taking blood thinners
  • Arrange for someone to drive you home
  • Follow any eating or drinking restrictions outlined by your doctor
  • Take your regular medicines as directed by your surgeon

What you can expect

During radiofrequency neurotomy
Radiofrequency neurotomy is an outpatient procedure, so you'll go home later that same day. The entire procedure usually takes about an hour.

You'll wear a hospital gown and lie on your stomach on an X-ray table. A special kind of X-ray machine, called a fluoroscope, will help the doctor position the radiofrequency needles precisely — so only the targeted nerve tissue will be affected.

An intravenous (IV) line will be placed in your arm or hand to deliver medication that will keep you comfortable during the procedure. Numbing medication will be injected into your skin before the radiofrequency needles are inserted.

After radiofrequency neurotomy
After the procedure, you'll be taken to another room to rest until you feel well enough to go home. You might notice some soreness in the area where the needles were inserted, but this usually goes away in a day or two.

Results

Radiofrequency works better for some people than others. A key factor is whether the nerves targeted by the procedure are the same nerves responsible for your pain. Symptom relief is temporary, ranging from a few months to more than a year.
