How Lumbar Radiofrequency Neurotomy Works
Lumbar radiofrequency neurotomy (RF neurotomy) targets the medial branch nerves responsible for transmitting pain from the facet joints in the lower back. Using radiofrequency energy, the procedure heats and disrupts these nerves, preventing them from sending pain signals to the brain. Unlike medications that only mask symptoms, RF neurotomy directly addresses the pain source, offering long-lasting relief.
Most patients experience significant pain reduction that can last anywhere from six months to over a year. This treatment is often recommended for individuals with chronic back pain due to conditions like arthritis or degenerative joint disease who have not found relief with conservative treatments.
What to Expect During and After the Procedure
The procedure is performed on an outpatient basis and typically takes less than an hour. A local anesthetic is applied to numb the treatment area, and fluoroscopic (X-ray) guidance ensures precise needle placement. A small electrode is then used to deliver controlled heat to the medial branch nerves, disrupting pain signals.
Recovery and Results:
- Most patients resume normal activities within 24 to 48 hours.
- Initial soreness at the injection site is common but subsides within a few days.
- Pain relief may take up to two weeks as the nerves stop transmitting pain signals.
