The spinal cord is a bundle of nerves that comes out of the base of the brain and runs down the center of the spine. The nerve roots branch out from the cord. In spinal stenosis, the narrowing usually occurs over time.
Musculoskeletal conditions like spinal stenosis and anterior cruciate ligament (ACL) tears in the knee affect people of all ages and can be debilitating. Recently reported long-term data from two large-scale studies funded in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases provide clinically valuable insights into the outcomes associated with treatments for these common, and sometimes costly, orthopaedic problems. Benefits of surgery for spinal stenosis diminish over time Data from the Spine Patient Outcomes Research Trial (SPORT) suggest that patients with severe low back pain caused by common spinal conditions who undergo surgery initially have
