Description
The medial border of ilium is the medially located margin of the bone. It extends from the iliac crest to the iliopubic eminence. It is one of the three borders of the ilium, the other two being the anterior and posterior borders, and it separates the iliac fossa from the sacropelvic surface of ilium. It begins as a slight ridge that passes inferiorly from the posterior one third of the iliac crest to the anterior margin of the auricular surface of ilium. It then travels along this margin, continues on as the arcuate line, and ends at the iliopubic eminence.
