Radiofrequency Ablation

Radiofrequency Ablation (RFA) is a minimally invasive, non-surgical pain-management procedure that uses heat generated by radio waves to temporarily disable specific small sensory nerves (such as the medial branch nerves) in the spine. It targets the small nerves that transmit pain signals from arthritic or degenerative facet joints (in the neck or lower back) and sacroiliac joints to the brain.

A specialized needle electrode is guided to the nerve using X-ray (fluoroscopy) imaging. Thermal energy heats the tip to cauterize or stun the nerve, stopping it from sending pain messages.

It disrupts pain transmission without affecting overall motor function, muscle strength, or limb movement.
