In the vertex presentation, the occiput typically is anterior and thus in an optimal position to negotiate the pelvic curve by extending the head. In an occiput posterior position, labor becomes prolonged, and more operative interventions are deemed necessary. [4] The prevalence of the persistent occiput posterior is given as 4.7%. [4]
In obstetrics, position is the orientation of the fetus in the womb, identified by the location of the presenting part of the fetus relative to the pelvis of the mother. Conventionally, it is the position assumed by the fetus before the process of birth, as the fetus assumes various positions and postures during the course of childbirth .
Various techniques have been tried to resolve an asynclitic position of the fetus. Vacuum extraction, a delivery assistance method used for prolonged or obstructed labor, has been shown to reverse the position from the less optimal one, known as occiput posterior or occiput transverse, to the more favorable position known as occiput anterior.

Left occipitoanterior (LOA)—the occiput is close to the vagina (hence known as vertex presentation), facing anteriorly (forward with mother standing) and toward the left. This is the most common position and lie. Right occipitoanterior (ROA)—the occiput faces anteriorly and toward the right.
Back labor may be noted when the baby is face up in the birth canal (occiput posterior), and not face down, so that the back of the baby's skull is pushed against the mother's sacrum. However back labor can also occur when the baby is in a different position. [ 3 ]
During a recent flight to San Juan, an airline passenger was asked to switch seats by three separate passengers as social media users chimed on Reddit about the indignity.
In obstetrics, Leopold maneuvers are a common and systematic way to determine the position of a fetus inside the woman's uterus. They are named after the gynecologist Christian Gerhard Leopold. They are also used to estimate term fetal weight. [1] The maneuvers consist of four distinct actions, each helping to determine the position of the fetus.
