IDET (INTRADISCAL
ELECTROTHERMAL THERAPY)

Why is this procedure done?
IDET is a procedure to manage discogenic pain (pain originating from the disc). The pain is caused by a tear, rip or injury to the disc. Some describe the condition as a leaky disc. The goal of IDET is to repair the tear or leaky disc. Those patients with back pain that have not had relief with conservative treatments including physical therapy, medications and spinal injections often see invasive surgery as their only option. IDET may be an alternative to more invasive surgery (i.e. Discectomy or Fusion). IDET can also be tried for individuals who are not candidates for surgery. A discogram is performed to assist in determining if a disc is causing your pain and if you are a candidate for the IDET procedure.

What happens during this procedure?
You will be placed on your stomach and the skin over the injection site(s) is cleaned. A local anesthetic numbs the skin. After the numbing medicine has been given time to be effective, the physician directs a needle, using x-ray guidance, into the disc. A heating probe is passed through the needle into the disc. The disc is then heated with the probe according to standard protocols. This heating changes the internal structure of the disc. This change in the disc structure is to help “heal” the disc and decrease your pain. When completed, the needle and probe will be removed, the area will be cleaned, and a band-aid will be placed. You will then be taken to the recovery area. Your corset will be placed and worn until you are home.

How do I prepare for the procedure?
You may not eat for 4 hours before the procedure. You can take your routine medications. If you have diabetes, please contact your treating provider for instructions on how to manage your diabetes medications. You must bring a driver. If you have any changes in your medical condition or are feeling sick, you should contact our office to inform our staff. You should stop all blood thinners, such as: Coumadin, Plavix, aspirin and most arthritis medications. You should stop herbal medicines and supplements one week before the procedure.

What are the side effects?
In general, IDET is a safe procedure. Serious side effects or complications are rare with IDET. However, similar to all injection procedures adverse effects are possible. The risks include but are not limited to increased pain, bleeding, and infection. To help prevent infection the procedure is performed under sterile conditions. Please discuss any specific concerns with your physician.

What happens after this procedure?
After the procedure you may not drive for 5 days or do strenuous activities. You will wear a lumbar brace for 6-8 weeks. You will need to limit your sitting time for 10- 20 minutes at a time for 3 days. If you have a sedentary or desk job, you may be able to return to work in 2 weeks. You will be started in physical therapy approximately one month after the IDET procedure.
