Anatomy of the Hip
The hip is comprised of three bones: the ilium, the ischium and the pubis. The ilium is the bone located at the highest point which we often refer to as the waist, while the pubis is located at the lowest point of the soft anterior abdominal wall. In addition, the ischium is best understood as the bony part in our buttocks that we sit on. The point where all three of these bones join and fuse together is known as the acetabellum. The acetabellum is the socket for the head of the femur – together they form the hip joint. The hip joint is much more stable than the other major ball-and-socket joint of the shoulder, due to their being a large contact surface between the femur and the acetabellum.
