Document Summary

There are 3 joints we will consider. The hip is the articulation between the head of the proximal femur and the acetabulum of the pelvis. The acetabulum is a deep socket that provides a great amount of bony constraint. The hip joint also possesses a large range of motion in all three planes. Holding the femoral head in the acetabular socket are some large ligaments. Within the socket itself is the ligamentum teres. Surrounding the socket to make it deeper is the acetabular labrum. Outside the socket are the iliofemoral ligament and the pubofemoral ligament on the anterior side. On the posterior side is the ischiofemoral ligament. In addition to the bony and ligamentous constraints, several muscles act to stabilize the femoral head within the acetabulum. These muscles have a large component toward the hip joint center. During walking gait, when you only have one foot on the ground, the pelvis wants to tilt toward your.
