Radiofrequency Ablation

Radiofrequency ablation (RFA) also called rhizotomy or neurotomy is a non-surgical procedure for treating pain. This technique employs radiofrequency waves to produce heat which leads to temporary desensitization of the nerves transmitting pain signals to the brain. This procedure is performed to treat painful facet joints in the spine that usually cause chronic low back pain and neck pain.

​

Radiofrequency ablation treatment is considered only after it is confirmed that the cause of neck or back pain lies in the facet joints and this is confirmed by performing diagnostic medial branch blocks or facet joint injections. Medial branch blocks and facet joint injection relieve pain for a short duration whereas radiofrequency ablation is intended to provide a longer time period of relief.
