Intradiscal electrothermal therapy (IDET) is a controversial, minimally invasive treatment for chronic low back pain related to a spinal disc.
Before an IDET procedure, you are given a sedative and a local anesthetic. Using "live" X-ray imaging (fluoroscopy), a doctor inserts a hollow needle containing a thin flexible tube (catheter) and heating element into the spinal disc. The catheter is positioned in a circle around the inside of the disc, and is then slowly heated to about 194°F (90°C). The heat is meant to kill the nerve fibers and toughen the disc tissue, sealing any small tears. Antibiotics, either given into a vein (intravenous) or injected into the disc, are used to prevent a disc infection.
