Getting a Laminectomy: Before, During, and After

Font Size

Laminectomy is one of the most common back surgeries. During a laminectomy, a surgeon removes the rear portion of one or more spinal bones (vertebrae). Bone spurs and ligaments that are pressing on nerves may be removed at the same time. Here's what to expect before, during, and after your laminectomy.

Before Your Laminectomy

During Your Laminectomy

Most laminectomies are performed with general anesthesia and mechanical ventilation. Here's what will happen:

  • The anesthesiologist or an assistant will place a mask over your face, delivering a mix of oxygen and anesthetic gas. You may also be given medicines through your veins to help you relax. Within a few breaths, you'll be unconscious. This is general anesthesia.
  • The anesthesiology professional will then insert a plastic tube through your mouth and vocal cords, into your windpipe, or trachea. This is called intubation.
  • During the surgery, a ventilator, or breathing machine, will pump air in and out of your lungs. Your vital signs will be continuously monitored throughout the operation.
  • You'll be rolled over into the face-down position to provide access to your back.

Next, the surgeon will perform the laminectomy:

  • The surgeon will make an incision in the skin of your back over the affected area. The muscles and soft tissues around the spine will be pulled to the side, exposing the spine.
  • The surgeon will then cut away bone, bone spurs, and ligaments that are compressing nerves. This is referred to as decompression. The surgeon may remove a small part or a large portion of several spinal bones, depending on your reason for the operation.
  • Some people may also undergo spinal fusion to stabilize the spine, receive a special implant that will help stabilize the bones in the lower back but not restrict motion in the same way a fusion does, have a disc removed, or have additional removal of bone to widen the passageway where nerves leave the spinal canal.

At the end of the surgery, the wound will be stitched, you'll be turned back over, the anesthesia will be turned off, and the breathing tube will be removed.
