Hip Dislocation

A hip dislocation occurs when the ball of the hip joint comes out of its socket. Usually, a large amount of force is necessary to dislocate the hip. The hip is a very stable joint that is reinforced by ligaments and large muscles.
The human hip, like the shoulder, is a ball and socket joint, in which the ball of one bone (the femur, or bone of the upper leg) fits into the socket of another (the pelvic bone). As the most flexible free-moving joint in the body, the normal hip can move backwards and forwards, from side-to-side, and can perform twisting motions.
Like other free-moving, or synovial joints, the hip contains a small amount of fluid, which lubricates the joint whenever you move it. It is held together with ligaments—straps of tough, sinewy tissue, which help prevent the joint from dislocating. Full function of the hip joint depends on the successful coordination of many interrelated parts, including bones, muscles, tendons, ligaments, and nerves.
There are three main ways the hip could dislocate: posteriorly, which is the most common; anteriorly; and centrally through the acetabulum in the pelvis.
In a posterior dislocation, there is usually a great deal of power brought to bear to a flexed knee and to the hip. Anterior dislocations occur when force is placed on a straightened leg. Central dislocations occur when force is sent primarily along the shaft of the femur - thigh bone
