What is non-radiographic axial spondyloarthritis?
Non-radiographic axial spondyloarthritis (nr-axSpA) is a type of arthritis that causes inflammation in the spine, which leads to lower back pain, morning stiffness, fatigue, and difficulty to carry out daily activities. Other areas, such as the chest, hip bone, and buttocks, can also be affected. Although patients do have symptoms, x-rays are unable to detect clear evidence of joint damage, but evidence of joint inflammation may appear on an MRI.
Signs and symptoms of nr-axSpA include:
- Morning back pain and stiffness
- Spinal inflammation
- Pain in lower back and hips
- Reduced physical function
- Less mobility
What makes nr-axSpA different from AS?
Non-radiographic axial spondyloarthritis (nr-axSpA) is distinguished from ankylosing spondylitis (AS) by how clear joint damage is on an x-ray.
