"The iliac crest is the superior border of the ilium extending from the anterior superior iliac spine to the posterior superior iliac spine. It has a longer ventral segment forming two-thirds of the crest and a smaller dorsal segment. The ventral segment has outer and inner lips and midway across it is the tubercle of the iliac crest. The summit of the crest is a little behind its midpoint, at the level of the third or fourth lumbar spine."

"The anterior border of the ilium descends to the acetabulum, and just short of it forms the rough anterior inferior iliac spine. The posterior border of the crest curves into a small notch with a small projection, called the posterior inferior iliac spine, below which the greater sciatic notch is formed at the junction of ilium and ischium. Beyond this it meets the medial border to form the sacropelvic surface. The medial border of the ilium forms the iliopectineal or iliopubic line, which exhibits an iliopectineal or iliopubic eminence and meets the superior pubic arch."

"The gluteal surface faces dorsolaterally, shows three long and prominent ridges called the posterior, anterior and inferior gluteal lines which roughly demarcate the attachments of the bulky gluteal muscles. The iliac fossa gives attachment to the iliacus muscle. The sacropelvic surface exhibits a large iliac tuberosity with an auricular surface or ear-like area articulating with the lateral mass of the sacrum and pelvic surface contributing to the lateral wall of the true pelvis."

"Single primary centre appears at eighth week of prenatal life. At birth the whole iliac crest, acetabular floor and acetabular cup (Y-shaped) are cartilaginous. Two secondary centres for the iliac crest appear at puberty and join between 15-25 years of age. Two centres of the acetabular cartilage fuse to form substantial part of the articular surface of acetabulum, and the anterior inferior iliac spine may be ossified from the triradiate centre or from a separate ossific nucleus."
