Intrapartum sonographic features of cephalopelvic disproportion in occiput anterior fetuses diagnosed with protracted active phase of labor

recent data from our group demonstrate that the flexion of the fetal head assessed by means of the occiput-spine angle (OSA) is associated with the mode of delivery in non-occiput posterior (OP) fetuses diagnosed with protracted active phase of labor1. When analyzing the relationship between the OSA and the sonographic station – assessed by means of the head-perineum distance (HPD) and the angle-of-progression (AoP) – cesarean delivery (CD) was found to occurr in two clusters of non-OP fetuses with high station, one characterized by head deflexion and another featured by favorable flexion1.
