Ankylosing Spondylitis: Definition, Uses, and Clinical Overview
Ankylosing Spondylitis is a chronic inflammatory condition that primarily affects the spine and sacroiliac joints. It belongs to a family of diseases called spondyloarthritis, which are immune-mediated arthritides. In practice, it is commonly discussed in orthopedic, rheumatology, primary care, and physical therapy settings when evaluating inflammatory back pain and progressive spinal stiffness. Its clinical relevance centers on pain, reduced mobility, structural fusion, and extra-articular features.
