What is the main function of the ilium?

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). 1 As such, the ilium serves a weight-bearing function and is part of the structure that ensures the spine is supported when the body is upright.

What muscles attach to ilium?

There are a large number of muscles that attach to the ilium. These include the tensor fascia latae, internal and external obliques, latissimus dorsi, gluteus maximus, medius and minimums, and rectus femoris.
