Radiofrequency ablation is a procedure that is designed to disrupt the small sensory nerves that go to the joints in the spine (the facets). First, you need to be diagnosed with a facet disorder. You must have lower back pain (or neck pain if in the cervical spine). A series of injections (fact blocks or medial branch blocks) must give you temporary relief of your local pain (see facet blocks on the web site).
If that is the case, then you could be a candidate for facet rhizotomies (radiofrequency ablations). The success rate for reasonable relief is 70%.
Radiofrequency ablation will not cure or relieve buttocks pain, leg pain or foot pain and numbness.
