Learn About Intradiscal Electrothermal Annuloplasty

Intradiscal electrothermal therapy (IDET) is a relatively new, minimally invasive treatment for spinal disc-related chronic low back pain.

Intradiscal Electrothermal Annuloplasty (IDET) is a minimally invasive treatment for chronic low back pain that results from certain types of painful degenerative disc disease or contained disc herniation. Successful IDET treatment may allow some patients to experience good or excellent pain relief without having to undergo major spinal surgery for disc removal and spinal fusion, or disc replacement.

Prior to undergoing an IDET procedure, patients usually have a preliminary discogram test in which the lumbar disc or discs that are abnormal (as seen on an MRI scan) and thought to be the cause of a patient’s back pain are injected with dye. Discogram tests that reproduce the patient’s pain and demonstrate tears or small herniations on the posterior wall (in the back of the disc) may signify a disc that may respond to IDET treatment. Recent improvements in the discogram test utilizing pressure controlled injection equipment have allowed physicians to more accurately identify truly symptomatic disc levels.
