Colorado Lumbar Discogram
Find Out What’s Causing Your Back Pain
The discogram procedure is a diagnostic test that determines if your neck
or back pain is the result of a damaged or displaced disc. “Discs”
are the cartilage padding between each vertebrae of the spine. They act
as stabilizers and shock absorbers. When one of these discs is damaged
it result in serious back pain.
Once our skilled physicians have diagnosed the cause of your back pain,
we will immediately start working with you to develop an effective treatment
plan. We strive to help all of our patients achieve a higher quality of life.
What are intervertebral discs?
Discs are cushioning quarter-sized structures made of cartilage and a watery
gel substance. Discs are shock absorbers between the spine bones (vertebrae).
Each vertebra has a disc above and below it, with the spine consisting
of vertebrae, discs, the spinal cord, and spinal nerves.
What conditions require a discogram?
Disc-related pain occurs with disc disease. Conditions that may require
you to have a discogram include:
- Degenerative disc disease
- Herniated disc
- Bulging disc
- Discogenic pain
What does the discogram show?
The discogram is used to determine which spinal discs are damaged and whether
or not those discs are the source of your pain. This test will show if
the disc has tears of the tough outer layers. When the doctor injects
the disc, the pressure may cause pain, which alerts the doctor that the
disc is problematic. The discogram does not show a herniated disc, nor
does it show the nerves or bones of the spine.
How do I prepare for the discogram?
The doctor will review the pros and cons of the discogram procedure. You
must understand the benefits and risks associated with the discogram before
it is scheduled. The doctor will review your medical history, conduct
a physical examination, and assess your back pain. Because the procedure
is minimally invasive, you will be given a sedative.
Avoid eating or drinking after midnight before your test, and notify the
doctor of any medications you take. You should arrive an hour before your
scheduled procedure, as certain laboratory tests may be required. Because
you cannot drive after the procedure, arrange for someone to drive you
home. Wear comfortable clothing and leave all valuables at home.
What can I expect during the lumbar discogram?
An interventional radiologist will discuss the procedure, answer your questions,
and have you sign a consent form. After you change into a procedure gown,
the nurse will place an IV catheter in your arm. Once you are positioned
face-down on the table, your back is cleaned with an antiseptic solution.
The nurse administers a sedative in your IV, and monitors are used to
assess blood pressure, heart rate, and oxygen level.
The doctor numbs the skin over the spine with a local anesthetic. Once
numb, the physician inserts a needle with catheter into the center of
the disc. Real-time x-ray is used to assure needle placement. A dye with
antibiotic is also injected into the disc. During injections, the doctor
will ask you questions about pain and what you feel. During the discogram,
the doctor may choose to inject and test several discs. A typical discogram
takes around 60 minutes.
What happens after the discogram test?
After the test, you are monitored in the recovery room for an hour. As
the local anesthetic wears off, expect to have some mild soreness. The
results of the discogram will be sent to your pain management specialist,
if he is not the doctor who performs the test.
Does the discogram work?
In a recent clinical study, the discogram was considered successful for
diagnosing discogenic pain. Adjusting for certain factors the predictive
value of discography was calculated at 60%.
