radiofrequency denervation

Doctors can deaden a nerve with a probe that generates intense heat (radiofrequency denervation or ablation) or intense cold (cryoanalgesia).

This diagnostic procedure can also be therapeutic; the injection of steroids or radiofrequency denervation of the medial branch can be added for refractory cases.
