Arcuate line of ilium
Arcuate Line of Ilium[edit | edit source]
The Arcuate Line of Ilium is a smooth, crescent-shaped ridge in the internal surface of the ilium, one of the bones that make up the human pelvis. It forms part of the boundary of the Iliac fossa and contributes to the brim of the Pelvic inlet.
Anatomy[edit | edit source]
The arcuate line of ilium is located approximately halfway between the anterior superior iliac spine and the posterior superior iliac spine. It runs inferiorly and anteriorly from the auricular surface of the ilium to the area of the pubic tubercle. The line marks the edge of the iliac fossa and represents the point where the body of the ilium joins the wing.
Clinical Significance[edit | edit source]
The arcuate line of ilium is an important anatomical landmark in several surgical procedures, including pelvic surgery and hip replacement. It is also used as a reference point in radiological examinations to assess the alignment and integrity of the pelvic ring.
