This iconic imagery of the progressively bent person has long been associated with Ankylosing Spondylitis. Figure 3 represents a person with a fused spine.

How does the disease progress to fusion?

The long standing inflammation characteristic of Ankylosing Spondylitis may lead to increasing damage to the spinal bones over time and could ultimately result in fusion of the spinal bones or ‘ankylosis’.[1]

Increasing pain, stiffness and immobility are usually the signs of progressing disease.[2][3][4]

How is Ankylosing Spondylitis different from other arthritic diseases?

Other arthritic diseases (like rheumatoid arthritis) result in bone destruction, but Ankylosing Spondylitis involves both bone destruction and new bone formation which results in 'Fusion'.[5]
