Pelvic adequacy refers to the ability of a woman's pelvis to allow the passage of a fetus during childbirth. It is a critical factor in determining whether a woman can deliver vaginally or if a cesarean section might be necessary. The pelvis is composed of several bones including the ilium, ischium, pubis, and sacrum, which form the pelvic cavity. An adequate pelvis has dimensions and shapes that facilitate the process of labor and delivery.
