What diseases commonly affect the sacroiliac joint?

The most common diseases affecting the sacroiliac joint are degenerative conditions, including arthritis and a chronic inflammatory disease known as ankylosing spondylitis. Most adults, especially men, have some deterioration of these joints. With advanced age, the sacroiliac joint may become greatly reduced or may no longer exist. This deterioration affects the joints that connect the sacrum to the ilium bones of the pelvis.
