Lumbar spinal stenosis is a condition in which there is tightness of all of the nerves in the lumbar spinal canal. This is caused by degeneration of the lumbar discs and ligaments and the discs bulge into the spinal canal from the front and the ligaments and other soft tissue bulge into the spinal canal from the back. This compresses the sac of nerves in the spinal canal as well as the exiting nerve roots. Patients experience pain and cramping in their legs, that is worse when they are standing and walking around, and relieved when they are sitting or leaning forward. Non-operative management includes anti-inflammatory medications, and physical therapy. Sometimes injections can be helpful. If non-operative management has not helped to decrease the pain or get the patient back to his or her activities, a surgery is recommended to alleviate pressure on the nerve roots. This surgery is called a lumbar laminectomy.
