Laminectomy is also known as decompression surgery. In this surgical procedure, a part of the vertebral bone called lamina is removed to create additional space. The lamina is the back part of the vertebrae that covers the spinal canal. Removing the lamina enlarges the spinal canal and thus, helps relieve pressure on the nerves and the spinal cord. Bony growths, especially in people with spinal arthritis, may put an additional pressure on the spinal cord. It may cause severe back pain and in some severe cases, can even cause paralysis. Narrowing of the space between the vertebrae is also known as spinal stenosis.
Laminectomy surgery, which is a form of spinal stenosis treatment, helps relieve pressure on the spinal cord and the nerves by creating a room between the vertebrae and the cord. When the pressure on the spinal cord in the case of lumbar spinal stenosis is relieved by creating a space between the lumbar vertebrae, the procedure is known as lumbar laminectomy. During a lumbar laminectomy, the surgeon may even remove the ligaments or bone spurs pressing the spinal cord.
