Diskectomy

A surgeon may perform disk removal (diskectomy) in these different ways.

• Microdiskectomy: When you have a microdiskectomy, the surgeon does not need to do much surgery on the bones, joints, ligaments, or muscles of your spine.
• Diskectomy in the lower part of your back (lumbar spine) may be part of a larger surgery that also includes a laminectomy, foraminotomy, or spinal fusion.
• Diskectomy in your neck (cervical spine) is most often done along with foraminotomy, or fusion.

Microdiskectomy is done in a hospital or outpatient surgical center. You will be given general anesthesia. You will be asleep and pain-free.

• The surgeon makes a small (1 to 1.5-inch, or 2.5 to 3.8-centimeter) incision (cut) on your back and moves the back muscles away from your spine. The surgeon uses a special microscope to see the problem disk or disks and nerves during surgery.
• The nerve root is located and gently moved away.
• The surgeon removes the injured disk tissue and pieces of the disk.
• The back muscles are returned to their normal place.
• The incision is closed with stitches or staples.
• The surgery takes about 1 to 2 hours.

Diskectomy and laminotomy are usually done in the hospital, using general anesthesia (asleep and pain-free).

• The surgeon makes a larger cut on your back over the spine.
• Muscles and tissue are gently moved to expose your spine.
• A small part of the lamina bone (part of the vertebrae that surrounds the spinal column and nerves) is cut away. The opening may be as large as the ligament that runs along your spine.
• A small hole is cut in the disk that is causing your symptoms. Material from inside the disk is removed. Other fragments of the disk may also be removed.

Risks of anesthesia and surgery in general are:

• Reactions to medicines
• Breathing problems
• Bleeding, blood clots, infection

Risks of this surgery are:

• Damage to the nerves that come out of the spine, causing weakness or pain that does not go away.
• Your back pain does not get better, or pain comes back later.
• Pain after surgery, if all the disk fragments are not removed.
• Spinal fluid may leak and cause headaches.
• The disk may bulge out again.
• Your spine may become more unstable and require more surgery.
• Infection that may require antibiotics, a longer hospital stay, or more surgery.

Tell your surgeon what medicines you are taking, even medicines, supplements, or herbs you bought without a prescription.

During the days before the surgery:

• Prepare your home for when you come back from the hospital.
• If you are a smoker, you need to stop, ideally 4 weeks before your surgery. Your recovery will be slower and possibly not as good if you continue to smoke. Ask your provider for help.
• Two weeks before surgery, you may be asked to stop taking medicines that make it harder for your blood to clot. These include aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), and other medicines like these.
• If you have diabetes, heart disease, or other medical problems, your surgeon will ask you to see the providers who treat you for those conditions before your surgery.
• Talk with your provider if you have been drinking a lot of alcohol, more than 1 or 2 drinks a day.
• Ask your surgeon which medicines you should still take on the day of the surgery.
• Always let your surgeon know about any cold, flu, fever, herpes breakout, or other illnesses you may have.
• You may want to visit the physical therapist to learn some exercises to do before surgery and to practice using crutches.

On the day of the surgery:

• Follow instructions about when to stop eating and drinking.
• Take the medicines your surgeon told you to take with a small sip of water.
• Bring your cane, walker, or wheelchair if you have one already. Also bring shoes with flat, nonskid soles.
• Follow instructions about when to arrive at the hospital. Arrive on time.

Your surgeon will ask you to get up and walk around as soon as your anesthesia wears off. Most people go home the day of surgery. Do not drive yourself home.

Follow instructions about how to care for yourself at home.

Most people have pain relief and can move better after surgery. Numbness and tingling should get better or disappear. Your pain, numbness, or weakness may not get better or go away if you had nerve damage before surgery, or if you have symptoms caused by other spinal conditions.

Further changes may occur in your spine over time and new symptoms may occur.

Talk with your provider about how to prevent future back problems.
