APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -In discussing the pelvis, a distinction can be made between the “pelvic spine” and the “pelvic girdle.” The pelvic girdle, also known as the os coxae, Latin for “bone of the hip, ‘’ consists of the fused bones identified individually as the ilium, ischium, and pubis.

Detailed explanation-2: -There are three bones of the pelvis: the hip bone, sacrum and coccyx. These bones connect the axial skeleton to the lower limbs, and therefore play a role in bearing the weight of the upper body.

Detailed explanation-3: -The pelvic skeleton is composed of two paired innominate bones, the sacrum, and the coccyx. The innominate bones are formed by three separate bones: the ilium, ischium, and pubis. The acetabulum, which is a socket for the head of the femur, is formed by the fusion of these three bones on each side laterally.

Detailed explanation-4: -The ilium is the physically largest of the three pelvic bones. It is located superiorly relative to the pubis and ischium. It is composed of a wing-shaped portion called the superior ala along with the inferior body. The rim of the superior ala is called the iliac crest.
