Overview

An x-ray may be helpful in the diagnosis of ankylosing spondylitis (AS). Findings on an x-ray suggestive of ankylosing spondylitis (AS) include erosion and ankylosis of the sacroiliac joints.

A standard anteroposterior (AP) plain x-ray of the pelvis helps in recognizing the AS.
Findings on an x-ray suggestive of/diagnostic of ankylosing spondylitis(AS) include^[1]^[2]^[3]
- Erosions
- Ankylosis
- Changes in joint width
- Sclerosis
Fusion and large erosions more obvious as the disease becomes more advanced.
With the severity in x-ray hip involvement we can correlates the severity of the spinal disease.^[4]
