I.D.E.T.

I.D.E.T (Intradiscal ElectroThermal Therapy)

You are a candidate for an I.D.E.T procedure since previously performed provocative discography has identified one or more discs as the possible source of your pain. The procedure is very similar to the previously performed provocative discography except for some details. This procedure involves using a special heating catheter to heat the inside of the disc. This changes the structure of the protein fibers that form the disc, and can stimulate the body to repair any tears in the disc that are responsible for your pain. In addition, heating the disc also can damage the pain sensing nerve endings in the disc, and block pain signals from the disc that you would normally feel. After having the procedure, you may have increased pain for a week or so before the pain begins to subside. It may take around 3 months before you will achieve maximum relief. You will receive instructions on what activities and exercises and when you can and cannot do them.

The procedure is very similar to the provocative discography performed earlier. An IV will first be placed in your arm. You will be placed prone (face down) on the fluoroscopy table. Your low back will be cleansed with an antiseptic and then numbed. The doctor will use X-ray to help guide the needle into the disc. Next, a thin catheter will be inserted through the needle into the disc. Then, the catheter will heat the disc for about 15 minutes. Next, an injection of antibiotics will be made into the disc to protect against infections. This may require the placement of a second needle. The procedure will take about 90 to 120 minutes. A Band-Aid will be applied to each injection site and you will be taken to the recovery area where the nurse will monitor your blood pressure and pulse for about 20 minutes. A nurse will review your discharge instructions with you before going home.
