APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The superior and inferior rami of the ischium and pubis bones come together to form this ring-like structure on each side of the pelvis.

Detailed explanation-2: -The hip bone is an irregularly shaped bone, also known as the pelvic girdle. It consists of three bones; ilium, ischium and pubis. These three bones are also known as the innominate bones, pelvic bones or coxal bones. They develop separately from each other and, in children, are connected only by cartilage.

Detailed explanation-3: -Anatomically, the acetabulum is formed by the fusion of the three pelvic bones: the ilium, ischium, and pubis. The ilium forms the upper boundary of the acetabulum, the ischium contributes to the posterior wall, and the pubis forms the anterior wall.

Detailed explanation-4: -As indicated above, the acetabulum is formed from parts of the ilium, ischium, and pubis. The acetabulum is the cup-shaped socket on the lateral aspect of the pelvis, which articulates with the head of the femur to form the hip joint.

Detailed explanation-5: -Ischiofemoral ligament: It attaches to the posterior surface of the acetabular rim and labrum and courses circumferentially around the joint to its insertion on the anterior aspect of the femur. The ischiofemoral ligament limits internal rotation and hip adduction with flexion.
