A chronic, inflammatory condition of the axial spine known as ankylosing spondylitis (AS) can cause a variety of clinical indications and symptoms. The most typical symptoms of the condition are growing spinal stiffness and chronic back pain. The condition is characterized by involvement of the spine, sacroiliac (SI) joints, peripheral joints, digits, and entheses. AS is characterized by reduced spinal mobility, postural irregularities, hip and buttock pain, peripheral arthritis, enthesitis, and dactylitis (sometimes known as "sausage digits"). This illness may potentially damage extra skeletal organs. The most prevalent extraarticular symptoms of AS are psoriasis (10%), acute anterior uveitis (25%–35%), and inflammatory bowel disease (up to 50%). A higher risk of cardiovascular disease is also linked to AS.
