The ilium, also referred to as the iliac bone, is the most prominent and topmost hip bone and a significant component of the pelvic girdle. The hip bone is formed in adults by joining this fan-shaped bone with the ischium and pubis (also known as the coxal bone).
As a result, the ilium performs a weight-bearing function and contributes to the structure that assures the spine is sustained when the body is upright. Therefore, it is a crucial component of the structure that enables movement.
The ilium, ischium, and pubis are separate bones in the developing skeleton that join to create a single bone in adults. This acetabulum is the site of this primary union.
The sacroiliac ligaments connect the sacrum and ilium. It is known as the sacroiliac joint and is motionless.
The primary function of the ilium bone is to support the upper body as a component of the pelvic bone and to help in walking and other forms of mobility. The ilium is connected to various nerves and muscles, which contributes to the function of this bone.
