Radiofrequency denervation (or ablation) is a day case procedure performed in the UK. Its purpose is to address neck or back pain stemming from degenerative changes or mechanical strain affecting the facet joints.

Typically, patients undergo diagnostic facet joint injections before this procedure. These injections serve to confirm that the pain originates from the facet joint nerves. These nerves transmit pain signals from the joints to the spinal cord and subsequently to the brain.

The objective of the denervation procedure is to generate heat in the tissue, effectively “cutting” these nerves to reduce pain transmission. This should provide long-lasting relief from the symptoms you’re experiencing, although it’s important to note that the nerves will regenerate over a period of eighteen months to two years.

During the procedure, the nerves are stimulated using a small electric current. This may cause a mild tingling sensation, and the muscles may twitch, but it is typically not painful. Sedation is administered while the nerves are being treated, and the entire procedure typically lasts approximately thirty to forty minutes.
