Radiofrequency neurotomy uses heat generated by radio waves to target specific nerves and temporarily turn off their ability to send pain signals.
Needles inserted through the skin near the painful area deliver the radio waves to the targeted nerves. A health care provider will typically use imaging scans during radiofrequency neurotomy to make sure the needles are positioned properly.
Radiofrequency neurotomy is most commonly used for pain in the back, neck, and buttocks (sacroiliac joint). It may also be helpful for long-term shoulder, knee, or hip joint pain.
Radiofrequency neurotomy is usually done by a provider who specializes in treating pain. The goal is to reduce chronic back, neck, hip, or knee pain that hasn’t improved with medications or physical therapy, or when surgery isn’t an option.
For example, your provider may suggest the procedure if you have back pain that:
Radiofrequency neurotomy might also be recommended to treat neck pain associated with whiplash.
To determine if you’re a good candidate for radiofrequency neurotomy, your provider may refer you to a pain specialist or order more tests.
For example, a test may be done to see if the nerves commonly targeted by the procedure are the same nerves responsible for your pain. A small amount of numbing medication is injected into the precise spots where the radiofrequency needles will go. If your pain significantly lessens, radiofrequency treatment at those spots may help you.
However, the provider may determine that a different procedure is needed to help your specific symptoms.
Let your provider know if you take blood-thinning medications. You may need to stop taking them for a period of time before the procedure.
Follow these steps:
Radiofrequency neurotomy is an outpatient procedure, so you’ll go home later that same day.
You’ll wear a hospital gown and lie on your stomach on an X-ray table. 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.
The provider will then use a special X-ray machine (fluoroscope) to guide the radiofrequency needles to the precise area — so only the targeted nerve tissue will be treated.
You’ll be taken to another room to rest until you feel ready 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.
When you get home:
Radiofrequency neurotomy isn’t a permanent fix for back or neck pain.
Studies on the success of treatment have been conflicting. Some people may have modest, short-term pain relief, while others might feel better for several months. Sometimes, the treatment does not improve pain or function at all.
For the treatment to work and for you to feel better, it’s important that the nerves targeted by the procedure are the same nerves responsible for your pain.
