| Cervical,
Thoracic, and Lumbar Discography Information:
What are the discs?
The discs are soft, cushion-like pads which separate the hard
vertebral bones of your spine. A disc may be painful when
it bulges, herniates, tears or degenerates and may cause pain
in your neck, mid-back, low back and/or arms, chest wall,
abdomen and legs. Other structures in your spine may also
cause similar pain such as the muscles, joints and nerves.
Usually, we have first determined that these other structures
are not your sole pain source (through history and physical
examination, review of x-rays, CT/MRI, and/or other diagnostic
injection procedures such as facet and sacroiliac joint injections
and nerve root blocks) before performing discography.
What is discography and why is it helpful?
Discography confirms or denies the disc(s) as a source of
your pain. It is a relatively simple procedure that uses a
small needle to inject contrast dye into your disc. MRI and
CT scans only demonstrate anatomy and cannot absolutely prove
your pain source. In many instances, the discs may be abnormal
on MRI or CT scans but not be a source of pain. Only discography,
which is a functional test, can tell if the disc itself is
a source of your pain. Therefore, discography is done to identify
painful disc(s) and help the surgeon plan the correct surgery
or avoid surgery that may not be beneficial. Discography is
usually done only if you think your pain is significant enough
for you to consider surgery or more advanced treatment options.
What will happen to me during the procedure?
An IV will be started so that antibiotics (to prevent infection)
and relaxation medicine can be given. You will lie on your
back for cervical discography, on your belly for thoracic
discography, and on your side for lumbar discography. Your
skin will be well cleaned. Next, the physician will numb a
small area of skin which may sting for a few seconds. Next,
the physician will use x-ray guidance to direct a small needle
into your disc. You may feel temporary discomfort as the needle
passes through the muscle or near a nerve root. The physician
may repeat this at several adjoining disc levels. After the
needles are in their proper locations, a small amount of contrast
dye is injected into each disc. If a disc is the source of
your usual pain the injection will temporarily reproduce your
symptoms. If a disc is not the source of your pain than the
injection will not reproduce your symptoms or cause any discomfort.
What should I do after the procedure?
Immediately afterwards you may be taken for a CT scan. You
should not drive for eight hours following this procedure.
You will wait 30-45 minutes after your CT scan to go home.
You will be given, if desired, a prescription for pain medication
over the next 2-3 days when your muscles may be sore.
General Pre/Post Instructions
You should eat a light, but not a full meal at least 2 hours
before the procedure. If you are an insulin dependent diabetic
do not alter your normal food intake. Take your routine medications
before the procedure (such as high blood pressure and diabetes
medications). Stop aspirin and all anti-inflammatory medications
(e.g. Motrin/Ibuprofen, Aleve, Relafen, Daypro) 3 days before
the procedure. These medicines may be re-started the day after
the procedure. You may take your regular pain medicine as
needed before/after the procedure. If you are on coumadin,
heparin, lovenex, plavix or ticlid you must notify my office
so that the timing of stopping these medications can be explained.
If you are on antibiotics please notify our office, we may
wait to do the procedure. If you have an active infection
or fever we will not do the procedure. You will be in the
hospital as an out-patient for 2-3 hours even though you see
the physician for 20 minutes. You will need to bring a driver
with you. You may return to your current level of activities
the next day including return to work.
