Background: Labour is a physiologic procedure in which the products of conceptions (i.e. the fetus, umbilical cord, membrane, and placenta) are barred out of the uterus. Aim of the work:To find out if a parameter resulting from U-S examinations (the occiput-spine angle (OSA)) had a correlation with the course and labour outcome. Patients and methods: this was a prospective observational study was conducted, consisted of 120 pregnant women attended to Al Azhar university El-Hussine hospital. Results: the mean of Occiput-spine angle in normal vaginal delivery group was 123.49 (± 5.16 SD) with range (116.00-135.00) while the mean of OSA in caesarian section delivery group was 115.55 (± 6.09 SD) with range (105.00-124.00). A highly significant change was found among the study groups regarding Occiput-spine angle. Conclusion: the prenatal sonographic evaluation of the flexion degree of the embryonic head by the OSA in fetus could be used to predict course and outcome of labor.

“…The angle between the chin and the chest can be measured ine the fetus in OP position and has been described as the "chin-to-chest" angle; a smaller angle signifies a more flexed head. 38 In contrast, a fetus in OA position as seen in Figure 12, demonstrates posterior midline structures that are more anterior to the maternal pubic bone.…”

“…37 When the OSA is not able to be seen, the degree of flexion and extension of the fetal head can be approximated by establishing whether the chin is seen tucked onto the fetal chest (flexed) or separate from the fetal chest (deflexed), also described as the chin-to-chest angle. 38 When imaging is done transperineally, the fetal head can be seen below the symphysis. 32,34,39…”

“…Adverse outcomes for both the mother and her baby have been associated with a prolonged duration in second stage of labor as well as higher likelihood of requiring an assisted birth. [53][54][55] The recommended duration of this stage in labor still remains debated world- wide. An obstetrician assesses the cause of the delay in labor and may propose an operative vaginal delivery (vacuum, forceps or caesarean section).…”

This recommendation document follows the mission of the World Association of Perinatal Medicine (WAPM) in collaboration with the Perinatal Medicine Foundation (PMF). We aim to bring together groups and individuals throughout the world for standardization to implement the ultrasound evaluation in labor ward and improve the clinical management of labor. Ultrasound in labor can be performed using a transabdominal or a transperineal approach depending upon which parameters are being assessed. During transabdominal imaging, fetal anatomy, presentation, liquor volume, and placental localization can be determined. The transperineal images depict images of the fetal head in which calculations to determine a proposed fetal head station can be made.
