The bony upper edge of the true (lesser) pelvis, which is the rim of the pelvic inlet (superior pelvic aperture). The pelvic brim comprises the pubic crest and pectineal line of each pubis, the arcuate line of each ilium, the inner edge of the alae of the sacrum, and the sacral promontory. The pelvic brim is oval shaped in females and heart shaped in males.
