Medial branch neurotomy

Medial Branch Neurotomy

What are medial branch block and neurotomy?

Facet joints connect your vertebrae to each other. Problems in these joints can cause chronic (long-term) pain in the neck or back.

Medial branch nerves are the nerves that carry many of the pain messages from your facet joints.

Radiofrequency medial branch neurotomy is a type of medial branch neurotomy that is used to relieve arthritis pain. It uses radio waves to damage nerves in your neck or back so that they can no longer send pain messages to your brain.

Before your doctor knows if a neurotomy will help you, you will get a medial branch block to find out if certain nerves are the ones that are a source of your pain. You will need two separate visits to the outpatient center or hospital to have both procedures.

You will need someone to drive you home.

How is a medial branch block done?

The doctor will use a tiny needle to numb the skin where you will get the block. Then the doctor puts the block needle into the numbed area. You may feel some pressure, but you should not feel pain. Using fluoroscopy (live X-ray) to guide the needle, the doctor injects medicine onto one or more nerves to make them numb.

If you get relief from your pain in the next 4 to 6 hours, it's a sign that those nerves may be contributing to your pain. The relief will last only a short time. You may then have a medial branch neurotomy at a later visit to try to get longer relief.

Call 911 anytime you think you may need emergency care. For example, call if:

  • You passed out (lost consciousness).
  • You have severe trouble breathing.
  • You are unable to move an arm or a leg at all.

  • You have new or worse symptoms in your arms, legs, chest, belly, or buttocks. Symptoms may include:

How do you prepare for a medial branch neurotomy?

Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.

Preparing for the procedure

  • Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
  • Understand exactly what procedure is planned, along with the risks, benefits, and other options.
  • Tell your doctor ALL the medicines, vitamins, supplements, and herbal remedies you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
  • If you take a medicine that prevents blood clots, your doctor may tell you to stop taking it before your procedure. Or your doctor may tell you to keep taking it. (These medicines include aspirin and other blood thinners.) Make sure that you understand exactly what your doctor wants you to do.
  • Make sure your doctor and the hospital have a copy of your advance directive. If you don’t have one, you may want to prepare one. It lets others know your health care wishes. It’s a good thing to have before any type of surgery or procedure.
