GROSS ANATOMY

Detailed explanation-1: -The Iliac fossa is a large depression on the anteromedial aspect of the flat, fan-shaped upper part (ala or wing) of the iliac bone (ilium). It forms the posterolateral wall of the greater (false) pelvis. The iliac fossa is limited superiorly by the iliac crest and anteriorly by the anterior border of the ilium.

Detailed explanation-2: -Important Landmarks The posterior superior spine: the terminus of the iliac crest on the rear-facing side of the ilium. The posterior inferior spine: below the posterior superior spine, and at the end of a larger, roughened region called the auricular surface.

Detailed explanation-3: -Iliac Crest You can find the iliac crests by placing the sides of your forefinger/hand in the fleshy part of the waist at the level of the umbilicus, move inferiorly and the first hard lumps you feel on each side are the iliac crests. This level corresponds to around L3-L4 lumbar vertebrae.

Detailed explanation-4: -The largest and uppermost bone of the hip, the ilium, also known as the iliac bone, is an essential part of the pelvic girdle. In adults, this fan-shaped bone is fused with two other bones, the ischium and pubis, to make the hip bone (often referred to as the coxal bone).
