ANKYLOSING SPONDYLITIS

​

Ankylosing Spondylitis is a chronic inflammatory disease affecting the sacroiliac joints, lumbar, dorsal and cervical spine, and tendon insertions.

​

The disease leads to ossification of tendon insertions (bamboo collar appearance) and limited joint amplitude.

Ankylosing spondylitis sometimes involves the eyes, heart and lungs.

​

It may also be associated with inflammatory bowel disease, such as Crohn's disease or RCUH (for Recto Colic Ulcer Hemorrhagic).

​

There are other types of ankylosing spondylitis, such as SAPHO syndrome (Synovitis, Acne, Pustulosis, Hyperostosis, Osteitis).
