A lumbar laminectomy is the surgical removal of parts of the spine bones in the lower back; these sections of bone are called the spinous processes and the laminae. Lumbar refers to the lower back. The procedure is used to free the nerve roots (points at which the nerve leaves the spine), which have become compressed.
The surgery involves removing the bone and other elements causing the pressure on the nerves, thus relieving leg pains and preventing further worsening of symptoms. This can improve your mobility and increase the distance you can walk without pain.
This procedure is used to relieve narrowing (stenosis) of the lumbar canal caused by degenerative or age-related changes in the structures of the spine. The spongy discs which separate the vertebrae (bones of the spine) and act as shock absorbers can dry out and shrink with age and the joints between the vertebrae can be affected by ‘wear and tear’, thus gradually losing the ability to be flexible.
