Radiofrequency ablation (RFA) uses heat generated by radio waves to disrupt the function of specific nerves that transmit pain signals from damaged facet joints or SI joints. At Merrillville Injury Care, RFA is performed by our pain management specialist for patients who have responded positively to diagnostic nerve blocks.
How Radiofrequency Ablation Works
During RFA, a specialized needle is positioned near the target nerve under fluoroscopic guidance. Radiofrequency energy is delivered through the needle, creating a small, precise lesion that disrupts the nerve’s ability to transmit pain signals. The procedure does not damage surrounding structures and preserves motor function. RFA is typically performed after diagnostic medial branch blocks or sacral lateral branch blocks have confirmed the specific nerves responsible for pain.
Duration of Relief and Candidacy
Radiofrequency ablation provides pain relief that typically lasts 6 to 18 months. Over time, treated nerves may regenerate, and the procedure can be repeated if pain returns. RFA is most commonly used for facet joint-mediated neck and back pain, SI joint pain, and other conditions where diagnostic blocks have identified a specific nerve target. It is an effective option for patients who have experienced temporary relief from injections but require a longer-lasting solution.
