Recovery After Surgery

Lumbar spinal stenosis, also called spinal stenosis, is a condition wherein the nerves that pass through the lumbar spine are pinched or compressed. The lumbar spine is found in the lower back, composed of five vertebral bodies. These are surrounded by nerves that are offshoots of the spinal cord. These nerves course through the spinal canal and pass through the foramen, which are small holes on the sides of the vertebral body. The narrowing passage could be the vertebral foramen (called foraminal stenosis) or the spinal canal itself (a condition called central stenosis).

This problem is often caused by arthritis. Like our other joints, the ones in the spine get brittle and rundown with age. Cartilage between the bones can get too worn to provide any cushioning. This would lead to osteophytes (also called bone spurs), overgrowth or hypertrophy of the ligamentous structures, or a decrease in the proper height of the discs between the vertebrae of the spine. Lumbar spinal stenosis can also be caused by an infection, tumor, or metabolic bone disorders, such as Paget’s disease. All of these situations can narrow the area where the nerves pass through.
