Abstract

Pelvis has four bones and four joints. True pelvis has an inlet, midcavity and an outlet. Anteroposterior, oblique and transverse diameter at the inlet is 11 cm, 12 cm, 13 cm respectively. At midcavity all these approximately equal to 12 cm and at the level of outlet it is 13 cm, 12 cm and 11 cm respectively. Diagonal is the only conjugate which can be measured clinically. Internal rotation takes place at the level of least pelvic dimension and this is the narrowest portion in the pelvis. Important skull sutures are sagittal, coronal, lambdoidal and frontal; and fontenelles are anterior and posterior. In cephalic presentation engagement is when biparietal diameter passes pelvic brim. Different presenting parts have different engaging diameter. Molding helps in adaptation of fetal head to unyielding pelvis. Caput succedaneum is not limited by suture lines and disappears by 24-36 hours. Commonest is vertex presentation in universal flexion, longtitudinal lie at left occipitoanterior/transverse position.
