The two hip bones join at the pubic symphysis and together with the sacrum and coccyx the pelvic part of the spine comprise the skeletal component of the pelvis – the pelvic girdle which surrounds the pelvic cavity. They are connected to the sacrum, which is part of the axial skeleton, at the 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.[2]
