Anatomy of the Hip

The hip is the joint that forms the junction between the legs and the trunk ; it supports the weight of the body and is therefore subjected to important constraints.

The top of the thighbone : the femur comes to fit into the iliac bone (the pelvis) at the level of a cavity called acetabulum.

The hip is a congruent (nested) joint, which plays a major role in walking as well as in flexion and rotation of the trunk.

Hip bones

The thighbone is the upper end of the femur (femoral head), which has the shape of a sphere coming to fit in the pelvis or iliac bone in a cavity called acetabulum.
The two bony parts are joined by an articular capsule and by ligaments.

Muscles and ligaments of the Hip

It is at the level of the hip that are attached the powerful muscles of the leg : the gluteal muscles, the pelvi-trochanterian (rotators of the hip) and the psoas (flexor). The hip is also supported by 4 strong ligaments that ensure its stability.
