Radiofrequency Ablation is a minimally invasive procedure used to reduce chronic pain by interrupting pain-signal transmission from a targeted sensory nerve.

1. Target Identification: The pain-generating nerve is identified using ultrasound or fluoroscopic guidance.

2. Probe Placement: A specialized RF needle or electrode is positioned close to the target nerve.

3. Sensory and Motor Testing: Mild electrical stimulation confirms correct placement and helps protect nearby motor nerves.

4. RF Energy Delivery: The generator delivers high-frequency alternating electrical current through the electrode.

5. Controlled Heat Generation: Electrical resistance in the surrounding tissue produces controlled heat at the electrode tip.

6. Thermal Lesion Formation: The heat creates a small, precisely controlled lesion in the targeted nerve tissue.

7. Pain-Signal Interruption: The treated nerve’s ability to transmit pain signals to the brain is reduced, providing pain relief.
