What causes ankylosing spondylitis?

Which area would be primarily affected by ankylosing spondylitis?
Ankylosing spondylitis (AS) (ank-ee-lo-zing spon-dee-li-tus) is a type of arthritis that mainly affects the back, by causing inflammation in the spine. This can make your back, rib cage and neck stiff and painful. It often starts in people who are in their late teens or 20s.
What is the primary manifestation of osteoarthritis?

Which joint disease is characterized by joint stiffness on movement?
Osteoarthritis symptoms often develop slowly and worsen over time. Signs and symptoms of osteoarthritis include: Pain. Affected joints might hurt during or after movement. Stiffness.
How does ankylosing spondylitis affect the body?
Ankylosing spondylitis (AS) causes inflammation in the joints of the spine, which can lead to severe, chronic pain. In advanced cases, it can cause bones to fuse in the spine, leading to a loss of mobility. Over time, AS may begin to affect other joints in the body, including the ribs, neck, knees, and feet.
Which finding in the physical assessment may be associated with osteoarthritis?
SIGNS / EXAM FINDINGS: Physical findings in osteoarthritic joints include bony enlargement, crepitus, cool effusions, and decreased range of motion. Tenderness on palpation at the joint line and pain on passive motion are also common, although not unique to OA.
What happens to the joint in rheumatoid arthritis What causes these changes?
Rheumatoid arthritis can cause pain, swelling and deformity. As the tissue that lines your joints (synovial membrane) becomes inflamed and thickened, fluid builds up and joints erode and degrade. Rheumatoid arthritis is a chronic inflammatory disorder that can affect more than just your joints.
