Question

What is the location of Ankylosing Spondylitis ?

Answer 1

Ankylosing spondylitis primarily affects the vertebral column, specifically the sacroiliac and facet joints, leading to pain, stiffness, and fusion.

Step-by-step explanation:

Ankylosing spondylitis is a chronic inflammatory disease that primarily affects the vertebral column or the spine. It specifically targets the sacroiliac joints and the facet joints of the spine, causing pain, stiffness, and fusion of the affected joints.

The sacroiliac joints are located between the sacrum (the triangular bone at the base of the spine) and the ilium (the large bone of the pelvis). The facet joints connect the individual vertebrae of the spine.

Over time, the inflammation and fusion can lead to a rigid and immobile spine, affecting a person's ability to move and perform daily activities.
