The Wing of Ilium is a significant part of the ilium, which is the largest bone of the pelvis. The wing of ilium, also known as the ala of ilium, is the large, fan-shaped portion of the ilium that forms the uppermost part of the hip bone.

Anatomy

The wing of ilium is broad and expanded and is divided into two parts: the body and the ala or wing. The body is the part of the ilium that joins with the ischium and the pubis to form the acetabulum, which is the socket for the femur or thigh bone. The ala or wing is the large, expanded portion that extends upwards from the body.

Function

The wing of ilium serves several important functions. It provides attachment for several muscles, including the gluteus maximus, gluteus medius, and iliacus. These muscles are crucial for movement and stability of the hip joint. The wing of ilium also forms part of the bony pelvis, which protects the pelvic organs and supports the weight of the upper body.

Clinical Significance

Injuries to the wing of ilium can occur as a result of trauma, such as falls or car accidents. These injuries can lead to pain, difficulty walking, and other complications. Treatment typically involves rest, pain management, and in some cases, surgery.
