ilium
Quick Summary
The ilium is the largest, uppermost, and dorsal bone of the pelvis. It is one of the three bones—along with the ischium and pubis—that fuse to form the hipbone in adults. Each hipbone, along with the sacrum, constitutes one half of the pelvis. The ilium plays a crucial role in forming the hip joint, where it articulates with the femur.123

The hip bone is characterized by the great length and forward extension of the ilium. The girdle is connected with the costal element of one vertebra, thus establishing a sacral region of…
