Ankylosing Spondylitis (AS) is arthritis of the spine that affects young people in their teens and twenties.
It causes inflammation of the spinal joints (vertebrae) that can lead to severe, chronic pain and discomfort. In the most advanced cases (but not in all cases), this inflammation can lead to new bone formation on the spine, causing the spine to fuse in a fixed, immobile position, sometimes creating a forward-stooped posture.
SAA is the first and remains the largerst resource for people affected by the disease. The Association's mission is to be a leader in the quest to cure ankylosing spondylitis and related diseases and to empower those affected to live life to the fullest.
