Its superior portion fuses with the body of ilium and the superior pubic ramus and forms the posteroinferior two fifths of the acetabulum. Its inferior portion consists of the ischial tuberosity and the ramus of ischium extends anteromedial from this portion.
The body of ischium consists of:
—three surfaces (femoral, pelvic, and dorsal);
