Interventional procedure overview of radiofrequency ablation for palliation of painful spinal metastases

There are no RCTs comparing the effect of RFA alone with other treatments for painful vertebral metastases.

Limited evidence included was mainly from small prospective and retrospective studies with short to medium term follow up.

RFA systems with different ablation methods (bipolar or monopolar RF electrodes) and temperatures, protocols were used in studies.

Outcomes were variable patient reported outcomes and are subject to high risk of bias.

Limited studies show that RFA is likely to provide effective short to mid-term (1 week to 6 months) pain relief.
