Spinal microdiskectomy; MicrodecompressionDefinition Return to top
Spinal microdiskectomy is surgery to remove disk fragments from a herniated disk, usually in the lower back (lumbar area).
Unlike lumbar spine surgery that requires a surgical cut about 2 to 5 inches long, microdiskectomy is less invasive, and done using a very small surgical cut about about 1 to 1 ½ inches long.
Description Return to top
Microdiskectomy is done in a hospital or outpatient surgical center while you are under local anesthesia (awake but pain-free) or general anesthesia (asleep and pain-free).
A special high-powered microscope magnifies the affected disk(s) and nerves, and guides the doctor during surgery.
The surgeon makes a small cut on your back and moves the back muscles away from the spine. After identifying and moving the nerve root, the surgeon removes the injured disk tissue and fragments. The back muscles are placed back into the normal position, and the wound is closed with stitches or staples.
Why the Procedure is Performed Return to top
Spinal microdiskectomy is done to relieve nerve pain and pressure. It may be performed in patients with the following conditions:
It's important to note that patients with low back pain are usually treated conservatively before surgery is considered. Traction, anti-inflammatory medications, physical therapy, and exercise are often prescribed. Over time, many of the symptoms of low back pain will improve without surgery.
Risks Return to top
Risks include:
Because of the small surgical cut, the doctor may miss some disk fragments. This could result in persistent pain.
Outlook (Prognosis) Return to top
Most patients have pain relief and improved function after surgery, and numbness and tingling gets better.
Recovery Return to top
You will be encouraged to get up and walk around as soon as your anesthesia wears off. Most patients are released the day of surgery.
Most patients typically are able to go back to normal activities shortly after surgery. However, you should avoid sitting for prolonged periods or lifting heavy objects. When lifting anything, be sure to lift with your knees instead of bending over. This is necessary to avoid further injury
If you work in an office, you’ll most likely be able to return to work within 2 to 4 weeks. But if your job is more physically demanding, you may have to wait for up to 3 months.
Your doctor may recommend an exercise or physical therapy program to speed your recovery.
