Hip bone sacroiliac joint. Each hip bone is connected to the corresponding femur (thigh bone) (forming the primary connection between the bones of the lower limb and the axial skeleton) through the large ball and socket joint of the hip. The hip bone is formed by three parts: ilium, ischium, and pubis. At birth, these three components are separated by hyaline cartilage. They join each other in a Y-shaped portion of cartilage in the acetabulum. By the end of puberty the three regions will have fused together, and by the age of 25 they will have ossified. The two hip bones join
Hip arthroscopy approach to gain access to the hip joint. This is an extensive approach, needing an often large incision over the side of the hip, with the detachment of the greater trochanter of the femur and its attached musculature to gain access to the joint. By using this approach, the ball of the hip joint can be rotated out of the socket (termed 'surgical dislocation'), giving 360-degree access to the whole joint. This approach, although considered generally safe, carries with it inherent risks, which is the case with all large incision surgery. The risks of infection and blood clots are always
