Verified step by step guidance1
Begin by understanding the anatomy of the pelvis, which is composed of three bones: the ilium, ischium, and pubis.
The acetabulum is a cup-shaped cavity located on the lateral aspect of the pelvis. It serves as the socket for the head of the femur, forming the hip joint.
Recognize that the acetabulum is formed by the fusion of the ilium, ischium, and pubis. Each of these bones contributes to the structure of the acetabulum.
The ilium is the largest and uppermost part of the pelvis, contributing to the superior portion of the acetabulum.
The ischium forms the lower and posterior part of the pelvis, while the pubis is located anteriorly. Both contribute to the acetabulum's structure, confirming that all three bones are involved in its formation.
