Radiofrequency ablation (RFA) of the lumbar spine is a minimally invasive technique to relieve chronic lower back pain by targeting specific nerves that transmit pain signals. During the procedure, a specialized needle electrode is precisely inserted near the targeted lumbar nerve under imaging guidance. Once correctly positioned, radiofrequency energy is delivered through the electrode, producing heat that deactivates the nerve’s ability to send pain signals.
RFA helps relieve lower back pain by interrupting pain pathways, reducing inflammation, and improving mobility. It can be especially beneficial for patients who have not found relief through other treatments such as medication, physical therapy, or steroid injections. The procedure typically results in pain relief lasting from several months to over a year, allowing patients to engage in daily activities with less discomfort and improved quality of life. Additionally, RFA has a low risk of complications and a shorter recovery time compared to surgical interventions.
