    Study Notes

    Bony Pelvis Structure

    • The bony pelvis consists of four bones: two innominate bones, the sacrum, and the coccyx.

    Sacroiliac Joint

    • The sacroiliac joint is formed by the articulation of the auricular surface of the sacrum with the auricular surface of the ilium.

    Pelvis Anatomical Position

    • The normal anatomical position of the pelvis is when the anterior superior iliac spines and the pubic symphysis are in the same vertical plane.

    Sacrum Structure

    • The base of the sacrum is formed from the superior surface of the first sacral vertebra.

    Ventral Sacral Foramina

    • The ventral sacral foramina on the pelvic surface of the sacrum transmit the anterior sacral nerves.

    Peritoneum Reflection

    • In males, the peritoneum reflects to form the rectovesical pouch at the level of the bladder neck.
    • In females, the peritoneum reflects to form the uterovesical pouch at the level of the uterus.
    • In females, the peritoneum covers the posterior aspect of the uterus after reflecting from the anterior abdominal wall.

    Recto-Uterine Pouch

    • In females, the peritoneum forms the recto-uterine pouch at a distance of about 5-6 cm above the anal orifice.

    Rectum Peritoneum Coverage

    • In males, the peritoneum covers the anterior and lateral surfaces of the rectum.
