What is Ankylosing Spondylitis? From Medical News Today
Ankylosing spondylitis is a type of chronic arthritis of the spine and the sacroiliac joints (in the pelvis). The inflammation of the vertebrae (spondylitis) can eventually lead to the fusion of the vertebrae – they cement together (ankylosis). This type of chronic arthritis affects the bones, muscles and ligaments. The long-term inflammation in the spine and sacroiliac joints cause severe pain and stiffness in the spinal area.
Ankylosing spondylitis belongs to a group of disorders known as seronegative spondyloarthropathies. Seronegative means patients do not have rheumatoid factor, an autoantibody. Spondyloarthropathies are a group of similar illnesses that generally cause joint and spine inflammation, examples include psoriatic arthritis, chronic reactive arthritis, idiopathic juvenile arthritis, and some inflammatory bowel diseases.
Some ankylosing spondylitis cases may have inflammation and pain in other parts of the body as well, such as the feet, knees, hips, ribs and shoulders. Occasionally, the area where the tendons and ligaments attach to the bones are affected, and symptoms develop in the bowel, eyes, and much more rarely the lungs and heart.
