The hip is responsible for the stabilization of a person’s body weight whether the person is static or dynamic. The physical joint is classified as a ball-and-socket joint, the head of the femur articulates with the acetabulum of the pelvis. With how the head is oriented in the socket, the joint is able to withstand tremendous amounts of pressure and allows it to be a strong and stable portion of the human anatomy. The design of the hip is actually very flexible and allows for a wide range of movements in different axis.
Anatomically, the “ball” portion of the joint consists of the head of the femur. The “socket”, or acetabulum, is a bit more complex. The entirety of the pelvis is made up of three individually fused bones: ilium, ischium, and pubis. During childhood and puberty, these three bones are separated by triradiate cartilage and around 15 to 17 years these bones start to fuse and the process is not complete until about 20 to 25 years of age. The ilium is the largest and most superior section of the pelvis and it contributes the superior portion of the acetabulum.

It is a fibrous sac that envelops the cavity of the synovial joint to keep the synovial fluid inside the capsule. For the hip joint specifically, the fibrous layer of the joint capsule attaches proximally on the hip bone to the bony rim of the acetabulum and the transverse acetabular ligament. Distally, it is attached to the femoral neck on the anterior side at the intertrochanteric line and the bottom of the grater trochanter. On the posterior side the joint capsule is arched and crosses the neck proximally to the intertrochanteric crest, but it is not attached. The joint capsule encases about two thirds of the neck and femur
