LAMINECTOMY, ALSO KNOWN AS DECOMPRESSIVE LAMINECTOMY is back surgery to remove the lamina, part of the bone that makes up the vertebra in the spine. Your symptoms may include pain or numbness in one or both legs. You may feel weakness or heaviness in your buttocks or legs. You may have problems emptying or controlling your bladder and bowel. You are more likely to have symptoms, or worse symptoms, when you are standing or walking.

Laminectomy may also be done to remove bone spurs in your spine. The surgery can take the pressure off of your spinal nerve and spinal cord. The procedure opens up your spinal canal to give your spinal nerves more room. You will be asleep and will receive general anesthesia to feel no pain.

Decompressive Laminectomy is often done to treat spinal stenosis. The procedure removes bones and damaged disks, and makes more room for your spinal nerve and column.


  • You will be positioned face down on the operating table. The surgeon will make an incision (cut) in the middle or your back or neck.
  • The skin, muscles and ligaments are moved to the side. Part of all of the lamina bones may be removed on both sides of your spine, along with the spinous process, the sharp part of your spine.
  • Your surgeon will then remove any small disk fragments, bone spurs or other soft tissue.
  • The muscles and other tissues are put back into place, and the skin is repaired.
  • Surgery will take approximately one to three hours.

You will get up and walk around as soon as the anesthesia wears off and go home the same day or surgery. Future spine problems are possible for all patients after Decompressive Laminectomy.
