Description: The pubis is the  anterior-most portion of the hip bones, and is formed by a body and a superior and an inferior ramus.  The superior ramus fuses with the ilium and the inferior ramus ischium on each side. The pubii delineate a central, triangle-shaped space named the obturator foramen, that is covered by the obturator membrane. The pubii meet anteriorly at the pubic symphysis where they articulate with a thick pubic cartilage. A wide angle is created by the upward convergence of the inferior rami from the ischial tuberosities laterally toward the midline.
