Great question — these two terms can definitely cause confusion! Here's a simple breakdown:
Spondylitis is an umbrella term for a group of inflammatory conditions that affect the spine and joints. It's also called spondyloarthritis. There are several types, including:
- Axial spondyloarthritis (axSpA) — affects the spine, neck, ribs, and hips
- Psoriatic arthritis
- Enteropathic arthritis
- Reactive arthritis Ankylosing spondylitis (AS) is a specific *type* of spondylitis. It falls under axial spondyloarthritis and is also called radiographic axSpA, meaning the damage it causes is visible on X-rays.
Think of it this way: all ankylosing spondylitis is spondylitis, but not all spondylitis is ankylosing spondylitis. What they share:
- Both involve inflammation of the spine and joints
- Both can cause lower back pain, hip pain, and stiffness
- Both are autoimmune in nature
- Both are managed with similar treatments like NSAIDs, DMARDs, and biologics
Key difference:
AS specifically involves structural damage visible on imaging, and over time can cause the vertebrae to fuse together, leading to reduced flexibility and posture changes. Other forms of spondylitis may not show this same progression.
It's always worth discussing your specific diagnosis with your rheumatologist, as the subtype can influence your treatment plan.
