Ankylosing Spondylitis, Radiologic Perspective (cont.)

Ankylosing Spondylitis Causes

Although the exact cause is unknown, ankylosing spondylitis is believed to be due to combination of a genetic influence and a triggering environmental factor. Approximately 90-95% of patients with ankylosing spondylitis have the tissue antigen human leukocyte antigen B27 (HLA-B27), compared to 7% in the general population. People with ankylosing spondylitis often have a family history of the disease.
