IDET (Introdiscal ElectroThermal Therapy)
Disc nucleoplasty, officially called percutaneous disc nucleoplasty, sends pulses of radio waves into the nucleus of a herniated disc. These radio waves vaporize small amounts of disc material, creating an empty space within the disc. The material that has bulged out of the disc wall will then move to fill in this empty space, restoring the disc wall to its original shape. With the disc wall no longer herniated, the pressure on nerve roots or the spinal cord will disappear, providing immediate pain relief.
IDET stands for intradiscal electrothermal therapy. IDET is a minimally invasive procedure used to relieve chronic or severe low-back pain caused by diseased, damaged, herniated or degenerated discs. Performed on an outpatient basis, IDET involves the application of an electrothermal catheter, a thin heating wire, which delivers precise amounts of heat to a disc. This allows the physician to shrink or seal any tears or cracks in the outer wall of the disc, reduce the bulge of inner disc material known as a herniated disc, and cauterize (burn) and thereby disable painful nerve endings affected by the deformed disc.
A discectomy removes part of a herniated disc because it is irritating a nerve and causing pain. In this minimally invasive procedure, a small needle is advanced to the herniated disc guided by a fluroscope. A probe with a rotating tip is then inserted through the needle to reach the herniated disc. When the probe is turned on, its tip drills away part of the disc nucleus, creating space for the herniated disc wall and relieving pressure on the nerve.
