Intradiscal Electrothermal Therapy
Intradiscal Electrothermal Therapy (IDET) is a minimally invasive treatment for spinal disc related chronic low back pain. This type of persistent disc pain is thought to be caused by nerve fibers that have grown from their normal location in the outer layers (annulus), or from an injury to the disc, causing the material in the middle of the disc (nucleus pulposus) to move into the outer layers of the disc (annulus) where nerves are, causing pain. Under x-ray guidance a thin flexible catheter is introduced into the problematic disc, and heats up. The proposed mechanism is that the heat causes contraction of the collagen fibers that may seal up painful tears and destruction of the painful nerve fibers, and stimulation of new collagen formation.
