Ankylosing spondylitis (AS) is itself a form of inflammatory arthritis, so joint inflammation is very much part of the picture. AS belongs to a family of conditions called spondyloarthritis (SpA), which causes widespread inflammation in the joints, spine, and the areas where tendons and ligaments attach to bone. While AS primarily targets the spine and pelvic joints, inflammation can affect multiple joints throughout the body. Some related conditions within the spondyloarthritis family, like psoriatic arthritis, can cause polyarthritis (inflammation in many joints at once), particularly in the fingers and toes.
Here are some key joint-related features of AS and its related conditions:
- Spine and sacroiliac joints — the most commonly affected areas in AS
- Enthesitis — inflammation where tendons and ligaments meet bone
- Peripheral joints — knees, ankles, and feet can also be affected
- Psoriatic arthritis — a related SpA condition that often involves multiple joints
It's always worth discussing any new or worsening joint symptoms with a rheumatologist, as they can help determine whether inflammation is spreading and adjust treatment accordingly.
