Intradiscal electrothermic therapy (IDET) for disc-related low back pain
Intradiscal electrothermic 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.
