McRoberts ’ maneuver increases fetal head angle of progression in the second stage of labor

Intrapartum angle of progression (AoP) is the leading sonographic parameter for the assessment of fetal head descent in labor. An AoP > 120° in the second stage of labor was correlated with spontaneous vaginal delivery and AoP > 145.5° with successful vacuum extraction.1‐3
