Iliac

The lower limb is specialized to support body weight and locomotion, the ability to move from one place to another and maintain balance, the condition of being evenly balanced. The lower limbs are connected to the trunk by the lower limb cingulate (hip and sacrum bones).

The lower limb skeleton is formed by the two hip bones, joined at the pubic symphysis and the sacrum. The lower limb cingulate and the sacrum together form the BONE PELVE.

The Iliac is a flat, flat, irregular, even bone consisting of the fusion of three bones:

Ilium & #8211; 2/3 higher

Ischia & #8211; 1/3 lower and posterior (more resistant)

Pubis & #8211; 1/3 lower and anterior

The bone has two faces, four edges and four angles.

Faces

Outer Face

Iliac Wing & #8211; posterior buttock, anterior buttock and inferior buttock

Acetabulum Cavity & #8211; Large articular cavity consisting of the union of the three hip bones: ilium, ischium and pubis. The acetabulum has the following structures: semilunar face, acetabulum fossa and acetabulum notch

Foramen thorium Obtorium & #8211; large rounded opening located between the ischium and the pubis

Inner Face

Iliac Fossa & #8211; large, smooth and concave face

Ear Face

Arched Line & #8211; divides ilium into body and wing

Borders

Top Edge

Iliac Crest & #8211; divided into: outer and inner lip and an intermediate line

Previous Edge

Anterosuperior Iliac Spine

Anteroinferior Iliac Spine

Iliopectinine Eminence & #8211; union point of ilium with pubis

Back Edge

Posterior Superior Iliac Spine

Lower Iliac Spine

Major Ischial Notch & #8211; superior to the sciatic spine

Ischial Spine & #8211; thin and pointed triangular eminence

Minor Ischial Notch & #8211; inferior to the sciatic spine

Ischial Tuber & #8211; large dilated protrusion

Bottom Edge

Ischiopubic Branch & #8211; union of the ischium with the pubis

Angles

Anterosuperior: Anterosuperior iliac spine

Posterosuperior: Posterosuperior iliac spine

Lower Poster: Sciatic Tuber

Lower Anterus: Pubis

THE Iliac articulates with three bones: Sacrum, Femur and Iliac on opposite side.
