Rhizotomy ablation (or RA) is a procedure used to reduce pain. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing pain signals from that specific area.
RA can be used to help patients with chronic (long-lasting) low-back and neck pain and pain related to the degeneration of joints from arthritis.
The degree of pain relief varies, depending on the cause and location of the pain. Pain relief from RFA can last from six to 12 months and in some cases, relief can last for years. More than 70% of patients treated with RFA experience pain relief.
