Description
The auricular surface of the ilium is the ear-shaped, articular area of the sacropelvic surface of ilium. It's located inferior to the iliac tuberosity and articulates with the auricular surface of the sacrum, forming the sacroiliac joint. Located immediately anterior to the auricular surface is a groove, the preauricular sulcus, which provides an attachment site for the anterior sacroiliac ligament.
