Laminectomy
Definition
Laminectomy is surgery to remove the lamina, two small bones that make up a vertebra, or bone spurs in your back. The procedure can take pressure off your spinal nerves or spinal column.
Alternative Names
Lumbar decompression; Decompressive laminectomy; Spine surgery - laminectomy
Description
Laminectomy opens up your spinal canal so your spinal nerves have more room. It is usually done along with a diskectomy, foraminotomy, and spinal fusion. You will be asleep and feel no pain (general anesthesia).
- You will lie face down on the operating table. The surgeon will make an incision (cut) in the middle of your back or neck.
- The skin, muscles, and ligaments are moved to the side. Your surgeon may use a surgical microscope to see inside your back.
- Part or 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 remove any small disk fragments, bone spurs, or other soft tissue.
- The surgeon may also do a foraminotomy (to widen the opening where nerve roots travel out of the spine) at this time.
- Your surgeon may do a spinal fusion to make sure your spinal column is stable after surgery.
- Surgery takes 1 to 3 hours.
Risks
Risks for any surgery are:
- Blood clots in the legs that may travel to the lungs
- Breathing problems
- Infection, including in the lungs (pneumonia), bladder, or kidney
- Blood loss
- Heart attack or stroke during surgery
- Reactions to medications
Risks for spine surgery are:
- Infection in wound or vertebral bones
- Damage to a spinal nerve, causing weakness, pain, or loss of feeling
- Partial or no relief of pain after surgery
- A return of back pain in the future
If you have spinal fusion, your spinal column above and below the fusion is more likely to give you problems in the future.
