The ischium bone (os ischii) has a thickened body (corpus ossis ischii), which completes the acetabulum from below and moves to the ischium (ramus ossis ischu) branch anteriorly. The body of the ischium with its branch forms an angle open anteriorly. In the region of the corner, the bone has a thickening - the ischial tuber (tuber ischiadicum). Above this hillock, from the posterior margin of the body, the sciatic islet (spina ischiadica), which divides the two notches: the incisura ischiadica minor and the upper ischisadica major. The branch of the ischium connects with the lower branch of the pubic bone, thus closing the obturatum (foramen obturatum) from below the oval form.
