What does "synclitism" mean?

Synclitism refers to a specific fetal positioning during labor and delivery in which both parietal eminences of the fetal skull enter the pelvic brim simultaneously. This alignment facilitates the engagement of the fetal head in the pelvis, which can aid in a smoother labor progression. When synclitism occurs, the baby's head is positioned straight in relation to the mother's pelvis, making it easier for the baby to navigate through the birth canal.

This positioning contrasts with asynclitism, where one side of the fetal head enters the pelvic cavity before the other, which can lead to difficulties during labor. Understanding synclitism is crucial for midwives and obstetric care providers as it directly impacts labor management and the potential for birth complications. The other options represent different fetal positions or orientations that do not pertain directly to the concept of synclitism.
