Hip joint. Close-up of the bones in the human hip joint from a female skeleton. The connection between the femur (the thigh bone, at centre) and the pelvis (at upper right) is seen here. The head of the femur forms a ball which fits securely into the acetabulum, a deep, cup-like cavity in the pelvis. This connection forms an extremely stable ball and socket joint. Tough ligaments around the joint further stabilise it. The hip joint supports the weight of the upper body as well as taking the strain of running, jumping and vigorous leg movements. Disorders of the hip include arthritis & dislocation,.
