Radiofrequency Ablation is an injection that is performed to treat pain due to irritation of the spinal facet joints.  Radiofrequency Ablation delivers radio waves (heat) through a needle to disrupt the small sensory nerve endings of your medial branch nerves and interrupt pain signals from the facet joints.  This procedure is considered quite effective and typically provides pain relief between 6-24 months after the procedure.  The nerve endings do regenerate; therefore the return of familiar pain may occur.  Fortunately, the procedure may be repeated if necessary and appropriate.  These injections are performed under fluoroscopic guidance (x-ray) to ensure safe placement of the needles to the intended site.
