What is ankylosing spondylitis? Ankylosing spondylitis is a type of arthritis that causes inflammation in certain parts of the spine. Over time, this inflammation in the joints and tissues of the spine can cause stiffness. In severe cases, this may cause the bones in the spine to grow together, which can lead to a rigid spine that is difficult to bend. Many people with ankylosing spondylitis have mild episodes of back pain and stiffness that come and go. But others have severe, ongoing back pain and stiffness. Other symptoms also may develop if other areas of the body are affected
What is spinal stenosis? Spinal stenosis happens when the spaces in the spine narrow and create pressure on the spinal cord and nerve roots. 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
