IDET: INTRADISCAL ELECTROTHERMAL THERAPY
What is a disc and how is IDET helpful?
The discs are the cushion-like pads that separate the vertebral bones of your spine. When a disc degenerates, tears or
herniates, it can cause pain in the back, buttocks, hips and legs. Discography is the gold standard to confirm or deny the
disc itself as a source of pain. If it is determined that a particular disc is the source of your pain, your physician can advise
you on an appropriate treatment method such as intradiscal electrothermal therapy (IDET). IDET is a minimally invasive
procedure which involves guiding a wire into a disc which is then heated in order to help heal tears within the disc and
reduce pain.
What happens during the procedure?
An IV will be started so that antibiotics (to prevent infection) and relaxation medication can be given. You will lie face
down on a procedure table. The physician will use fluoroscopic (x-ray) guidance to visualize the spine. The physician
will scrub your skin with sterile soap and place a drape on your low back. The physician will numb a small area of skin
with anesthetic medication. After the anesthetic has been given time to be effective, the physician will then direct a very
small needle using fluoroscopic guidance into the disc. You may feel temporary discomfort as the needle passes through
the outside of the disc. The next step is to insert the electrothermal wire through the needle into the disc. The heating
element is activated, and the heat then increased slowly over the next 15 minutes. As the heat increases into the treatment
range, you might experience some discomfort. Your physician will monitor your responses during the procedure to insure
that any discomfort you feel is well controlled.
What happens after the procedure?
Immediately after the procedure, you will go to a recovery area where you will be monitored for approximately 30
minutes. After discharge, you will not be able to drive the day of the procedure.
For the first 7-10 days after your procedure, you may experience a moderate increase in back pain; do not expect your
typical pain to disappear immediately. Rest, ice, and anti-inflammatory and/or pain medications may help minimize this
discomfort. Any new or unusual symptoms (ie. fever, rash, or numbness) should be reported to your physician
immediately. If you experience a marked reduction in pain, do not exert yourself during this time as this may negatively
affect the overall outcome. Housework, lifting, or bending should not be done. In addition, you should not return to work
during the first week even if you have a sedentary job. You should plan to discuss your return to work with your
physician if you have a more active job. Note, while you should generally be resting during the first week, short walks up
to 15 to 20 minutes are permitted.
For the first month after the procedure, your disc is continuing to heal. You may begin to feel a reduction in pain during
this time however pain reduction usually occurs over 3 - 4 months. Anti-inflammatory medications and/or pain
medication may be prescribed if needed to control any low back pain. Applying ice up to 20 minutes at a time 3-5 times a
day is also advisable to reduce any discomfort.
During this first month, you must treat your back carefully. Absolutely no bending, twisting, or heavy lifting. No sport
activities including running, biking, golf, tennis, skiing, etc. You do not have to abstain from sexual activity, but be
careful not to exert your back. Your physician will guide you regarding rehabilitation exercises after your procedure. If
you have been performing strenuous rehabilitation exercises before the procedure, you will not immediately return to that
level of exercise, but to a more moderate level that will be gradually increased as you improve. Be sure to ask your
physician for a post-operative exercise program.
In the 2nd, 3rd, and 4th months after the procedure, you should continue to maintain good body mechanics ie. avoiding
bending improperly. Your physician will help you advance your flexibility and strength. If you plan to return to athletic
pursuits, specialized advanced training may be undertaken to help achieve your goal.
