Hip joint anatomy in 3D

The hip joint is formed where the head of the femur fits into the deep socket (acetabulum) on the side of the hip bone, linking the pelvis to the leg. Its deep socket and strong ligaments make it more stable than the shoulder joint, with a narrower range of movement. When we stand it passes the weight of the upper body to the legs.
