Beschreibung

The superior circumference forms the brim of the pelvis, the included space being called the pelvic inlet (superior aperture).

It is formed laterally by the pectineal and arcuate lines, in front by the crests of the pubes, and behind by the anterior margin of the base of the sacrum and sacrovertebral angle. The superior aperture is somewhat heart-shaped, obtusely pointed in front, diverging on either side, and encroached upon behind by the projection forward of the promontory of the sacrum.

It has three principal diameters: antero-posterior, transverse, and oblique.
