The patient is sedated with the help of anesthesia. The surgeon makes an incision along the midline of the back and moves aside the skin, muscles, fat and other soft tissues to expose vertebral bones.
Removal of Spinous Process
The surgeon removes the spinous process. It is the portion of the vertebra that protrudes furthest from the back of the spine.
Removal of Lamina
The surgeon then removes the lamina. It is the roof of the bone over the back of the spinal canal. Removal of lamina opens up the spinal canal and, therefore, takes pressure off the spinal cord or nerves.
Removal of Bone Spurs & Fragments
The surgeon also removes any bone spurs and bone fragments that may be pinching the nerves.
The procedure ends when the surgeon eases the soft tissues and muscles back in their place and closes the incision.
