What is iliac furrows?

Iliac furrows, also known as iliac crests or iliac lines, are the anatomical landmarks located on the upper part of the pelvis. They are formed by the outward projection of the bone structure that makes up the iliac wings and mark the upper border of the hip bones. Iliac furrows are often used as a reference point for locating other anatomical structures and landmarks, such as the iliac spines, inguinal ligaments, and abdominal muscles. They are also important in assessing the body composition of individuals, as they are often used as a measurement site for body fat percentages. In some cases, a visible iliac furrow may indicate a low body fat percentage, while a lack of definition in the area can indicate a higher body fat percentage.
