Ankylosing spondylitis (AS) is a chronic inflammatory condition that mainly affects the spine. It causes inflammation of the joints between the vertebrae, which are the bones in your spine. Over time, this inflammation can lead to the vertebrae fusing together, making the spine less flexible.
Lumbar Spondylitis: Lumbar spondylitis, on the other hand, is a type of spondylosis. It’s a condition where the discs and bones in the lower back, called the lumbar region, start to wear down and change due to aging and daily wear and tear.
