Fact: More than 100 forms of arthritis exist, including ankylosing spondylitis and rheumatoid arthritis. Both are inflammatory and systemic, but ankylosing spondylitis is part of a disease group called spondyloarthritis, while rheumatoid arthritis is a separate disease under the arthritis umbrella. Ankylosing spondylitis is characterized by enthesitis, or inflammation where ligaments and tendons attach to bone; rheumatoid arthritis is characterized by synovitis, or inflammation inside the joints.

Fact: Ankylosing spondylitis affects every person differently including disease severity; the types, location and number of symptoms; the age of onset and length of time to diagnosis; the timeline of progression and inactivity; reaction to treatments; and presence or lack of imaging or other evidence of disease activity.
Ankylosing spondylitis is a complex, common disease that affects millions of people. Despite its prevalence, inaccurate information is easy to find. Keep looking for the facts!
