A Radiofrequency Ablation Rhizotomy is a procedure using a specialized instrument/machine that generates a radio-frequency current. A special needle is placed at the nerve which carries pain from the spinal facet joints or the sacroiliac joints to the spinal cord and the brain. The radiofrequency current is passed through the needle. The current generates heat which destroys/lesions the nerve that transmits pain signals to the central nervous system thereby alleviating or eliminating the patient's perception of pain.

 

Radiofrequency Ablation procedures are almost always utilized as part of a comprehensive pain management program.
