What is Spondylitis?

According to the Spondylitis Association of America:

‘Spondylitis (pronounced spon-d-lie-tiss) is the name given to a group of chronic or long lasting diseases also called Spondyloarthritis (spon-dyl-oh-arthritis) or Spondyloarthropathy (spon-d-low-are-throp-ah-thee). These diseases are forms of inflammatory arthritis that primarily affect the spine, although other joints and organs can become involved.’
