RadioFrequency Ablation for Back Pain
Chronic neck and back pain can interfere with everyday life. Medications and other noninvasive treatments may help some patients manage their pain, but other patients may need further treatment to manage their neck and back pain. If patients do not find relief from noninvasive treatments, then radiofrequency ablation could relieve their pain. Radiofrequency ablation is a procedure designed to decrease pain signals from the nerves where the back pain originates.
When Is Radiofrequency Ablation Recommended?
Radiofrequency ablation may be an option for patients with chronic neck or back pain caused by arthritis in the spine. There are two types of joints in the spine: facet joints and sacroiliac joints. Facet joints are the tiny joints at the back of the spine that stabilize the vertebrae. Sacroiliac joints are located at the bottom of the spine, between the base of the spine and the pelvic bone. These joints can be subjected to degenerative changes from arthritis, which puts pressure on the spinal nerves, leading to neck or back pain.
The goal of radiofrequency ablation is to eliminate or reduce pain signals caused by this compression of the spinal nerves. Although it is a safe procedure with few associated complications, radiofrequency ablation may not be recommended for some patients. Radiofrequency ablation is not suitable for patients with active infections or bleeding disorders. Dr. Trujillo examines patients prior to the procedure to determine whether or not radiofrequency ablation is an option.

Radiofrequency Ablation Procedure
Patients are typically administered IV sedation prior to the radiofrequency ablation procedure. Local anesthetic is also administered in the area where the procedure will be done. Patients are typically awake during this procedure so that they can provide feedback.
Once anesthesia has been administered, Dr. Trujillo will use x-ray guidance to insert the radiofrequency needle into the correct area, alongside the nerves causing pain. A mild electrical current is then passed through the needle to verify correct placement. If placed correctly, the electrical current will briefly create a tingling sensation and may cause a muscle twitch in the neck or back. Once the target nerves are located, local anesthesia may be administered to minimize pain during the procedure.
Radiofrequency currents are then passed through the needle, creating a lesion on the nerve. This lesion disrupts the pain signals sent to the brain. Dr. Trujillo will repeat this process for additional nerves as needed. The procedure typically lasts between 30 and 90 minutes.
what to expect after radiofrequency ablation
Patients are able to return home the day of the procedure, but will need to make arrangements to have someone drive them home. The treatment area may be sore for the first few days after the procedure. Patients may experience muscle spasms and irritation for about one to two weeks after the procedure. Side effects and complications are rare with radiofrequency ablation, but may include:
- Burning pain and hypersensitivity of the treatment area for one to two weeks
- Numbness of the skin over the treatment area
- Leg numbness due to local anesthesia (this should subside after a few hours)
- Permanent nerve pain
Recovery From Back Pain Treatment
Patients may apply ice to the back to help with soreness. While there are no absolute activity restrictions after radiofrequency ablation, patients should avoid painful activities and make sure that they are getting enough rest while recovering. The degree and longevity of pain relief can vary from patient to patient. Most patients experience full pain relief two to three weeks after the procedure.
For many patients, this pain relief can last for 6 to 12 months. The nerves regenerate over time, causing the recurrence of pain. In other cases, pain relief can last for years or may never recur at all.
