Minimally Invasive Back Pain Treatment in Colorado
Also called the minimally invasive lumbar discectomy (MILD), the percutaneous
discectomy is recommended for people who have not responded to usual treatments.
A percutaneous discectomy involves the removal of central disc material
without removing the actual disc itself.
Who is a candidate for the percutaneous discectomy?
When you see the pain management professional, he will review your MRI
scan to assess your disc problem. The percutaneous discectomy is used
to prevent major spine surgery. You may be a candidate if:
- You are diagnosed with a disc bulge, but the disc has not ruptured.
- The pain is severe enough to keep you from walking and doing usual activities.
- The pain has not improved after four or more weeks of non-invasive conventional
- You have spinal stenosis.
- There is no disc material in the spinal canal.
- If nerve damage that affects your legs will continue to progress without
How do I prepare for the percutaneous discectomy?
Before the surgery, you meet with the physician to discuss your goals,
your current condition, and your medical history. If the doctor decides
the percutaneous discectomy would work for you, he may schedule additional
imaging tests. Once you agree to the procedure, the doctor discusses the
risks and benefits and has you sign a consent form. Because a sedative
is given, you should not eat/drink 8 hours before surgery time, and must
arrange to have a ride home.
How is the MILD percutaneous discectomy done?
After the nurse starts an IV line in your arm, you are connected to monitoring
devices to assess heart rate, oxygen level, and blood pressure. A mild
sedative is given after you are positioned face-down on the procedure
table. The doctor cleans the skin over the targeted disc with an antiseptic,
and uses a tiny needle and syringe to numb the skin with an anesthetic.
A small incision is made, and the doctor inserts the decompressor needle
into the disc. To assure correct needle placement, x-ray technology guides
the doctor’s vision. Using gentle suction, the disc material causing
the bulge or displacement is removed. The doctor may use a laser to destroy
portions of the herniated disc to remove it more easily.
What can I expect after the percutaneous discectomy procedure?
The procedure is done in an outpatient facility, so you go home the same
day. Expect 20 minutes for preparation, 30 minutes for the procedure,
and 2 hours for the recovery. A nurse monitors you while you wake up from
sedation. You will have some postoperative pain, but the nurse can give
you medication. Once you go home, we recommend resting for a couple days,
and avoid lifting, excessive bending, and twisting.
Does the percutaneous discectomy work?
According to clinical studies, the percutaneous discectomy has a 70-80%
success rate. Most patients can return to normal activities within a week,
report decreased or no pain, and are happy with the procedure. In a study
that spanned 14 years, and involved over 1,350 patients, researchers found
that 58% of people are satisfied with the procedure at two months, and
68% are pleased at six months. People with discogenic pain, the elderly,
and those who had previous back surgery tend to have higher satisfaction
rates with this procedure.
