spondylitis is a term used to describe a group of arthritis-based spine conditions that cause inflammation in the vertebrae and sometimes joints of the spine. Spondylitis generally occurs in the lowest section of the lumbar spine the sacroiliac joint that connects the pelvis to the spine. One of the most common forms of spondylitis found in the SI joint is ankylosing spondylitis.
Patients diagnosed with spondylitis may experience a range of symptoms, including immobility of the spine, decreased range of motion, chronic pain, and deformed spine curvature. If you suspect you have spondylitis, consult your doctor and plan to discuss your symptoms and undergo spinal tests to determine the cause of your pain
