The femoral-acetabular joint is formed by the?
Approximating union of the head of the femur with the acetabulum of the pelvis.
What is the femoral-acetabular articulation sometimes referred as?
As the coxofemoral joint
The femoral-acetabular forms what type of joint?
Forms a diarthrodial ball and socket joint
This joint is also called enarthrodial is a multiaxial
The hip has how many degrees of freedom?
3
What is the functional role of the Hip?
It is designed for maximal stability while providing considerable mobility.
What are the primary functions of the Hip?
Weight bearing support
Force transmission for ground reaction forces
Where can referred pain in the hip region be associated?
Lumbo-sacral region Knee Anterior-Medial- lateral thigh Groin Buttock Foot/ankle

Horseshoe-shaped
What is located in the deep acetabular fossa?
Synovial covered fibroelastic fat pad
