COXAL JOINT ANATOMY

The hip is one of the ball and socket free motion joints that constructed by the head of the femur and the conjunction of the acetabulum of the os coxae. Given that it must be able to withstand the weight of the body over a lifetime, its construction is much greater and stronger than that of the shoulder joint.

COXAL JOINT STRUCTURE

Several ligaments work in cohesive grandeur with the muscles to provide stability for the hip joint capsule, which in turn secures the hip joints in place. The anterior iliofemoral and the pubifemoral consist of the main ligaments responsible for providing security. The aschiofemoral ligament secures the hip’s posterior position. Attached to the head of the femur to the acetabulum is the ligamentum capitis femoris which is positioned within the articular capsule.

COXAL JOINT FUNCTIONS

This ligament is basically slack and is not particularly responsible for holding firm the femur into the socket. Instead it is responsible for supplying the head of the femur with a blood supply via a small artery that this ligament holds. Connected to the joint capsule by way of connection to the acetubular notch is the transverse acetubular ligament. This ligament also connects to the ligamentum capitis femoris. A fibrocartilaginous ring runs around the head of the femur where it conjoins with the acetabulum and attaches to its margins is the acetabular labrum.
