Description

The sacroiliac joint is an amphiarthrodial joint, formed between the auricular surfaces of the sacrum and the ilium.

The articular surface of each bone is covered with a thin plate of cartilage, thicker on the sacrum than on the ilium. These cartilaginous plates are in close contact with each other, and to a certain extent are united together by irregular patches of softer fibrocartilage, and at their upper and posterior part by fine interosseous fibers. In a considerable part of their extent, especially in advanced life, they are separated by a space containing a synovia-like fluid, and hence the joint presents the characteristics of a diarthrosis.

The ligaments of the sacroiliac joint are:

  • Anterior sacroiliac ligament
  • Interosseous sacroiliac ligament
  • Posterior sacroiliac ligament
