Intradiscal electrothermal therapy or IDET, is a new minimally invasive treatment option for patientsIntradiscal electrothermal therapy with low back pain caused by tears or cracks due to ageing in the outer wall of the intervertebral disc. Since there are many nerve endings and blood vessels at these points, these fissures are a chronic source of pain in many patients. In addition, the inner tissue (nucleus) will cause the disc to herniate into these fissures in the outer region of the disc, likewise stimulating pain sensors within the disc.
This is a minimally invasive treatment which involves the use of heat to modify the collagen fibers of the disc and destroy the pain receptors in that area. A wire known as an electrothermal catheter is inserted through a small incision on the back and into the disc with the guidance of a special X-ray camera, through which an electrical current passes is inserted into the disc. The catheter heats the disc to a temperature of 90° C over the course of 15-20 minutes. The physician applies controlled levels of thermal energy (heat) to a broad section of the affected disc wall. This heat contracts and thickens the collagen of the disc wall and raises the temperature of the nerve endings. Therapy may result in contraction or closure of the disc wall fissures, a reduction in the bulge of the inner disk material and a desensitization of the pain sensors within the disc.
IDET therapy acts only on the tissues of the disc and does not relieve symptoms arising from other spinal structures, such as nerve roots or spinal joints. Proper diagnosis needs to be done to ensure that the disc is the primary source of pain. Magnetic Resonance Imaging (MRI) or injections of dye into the disc (discography) may be done to confirm the diagnosis.
IDET therapy is usually performed on an outpatient basis under local anesthesia and mild sedation. The patient will be awake and can give feedback to the physician. Under the guidance from C-Arm which is an instant X-ray imaging unit, the physician inserts a needle into the disc. The catheter is passed thru this needle and into the disc. Once in the appropriate position, the heating of the catheter will be done which raises the disc wall temperature. The pain which was there, if felt during the process, indicates that the heat is being applied to the correct areas. Both the catheter and needle are removed after the procedure, and the patient can return home the same day.
SpineCATH IDET therapy, like any surgical procedure, has some risks. Not all patients will find relief for their back pain and relieved symptoms may recur over time. Please consult your physician about the risks and potential complications of SpineCATH IDET therapy. Many additional factors may prevent your physician from recommending SpineCATH IDET therapy for your condition. Such factors may include, but are not limited to, very narrow disc height, severe disc herniation, spinal instability, very advanced stages of disc degeneration, or various general health concerns.
After the Procedure
There would be discomfort for several days and pain medication may be prescribed. The disc healing process will take up to 12 to 16 weeks following the procedure and it is very important to take utmost care during this period. Your physician will provide you with activity and physical rehabilitation guidelines. Studies have shown that it is during this time that most patients begin to experience relief from their lower back pain symptoms, a reduction or elimination of any medication use and an increase in their functional abilities. Improvements may continue up to six months following the procedure.
