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 .
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] The vertex presentations are further classified according to the position of the occiput, both right, left, or transverse and anterior or posterior:
Presentation of twins in Der Rosengarten ("The Rose Garden"), a German standard medical text for midwives published in 1513. In obstetrics, the presentation of a fetus about to be born specifies which anatomical part of the fetus is leading, that is, is closest to the pelvic inlet of the birth canal.
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.

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.
Back labor can be painful. Relief may be sought by trying to find a comfortable position or using a birth ball. Back labor (less commonly called posterior labor [1] [2]) is a term referring to sensations of pain or discomfort that occur in the lower back, just above the tailbone, to a mother during childbirth.

Fetal position (British English: also foetal) is the positioning of the body of a prenatal fetus as it develops. In this position, the back is curved, the head is bowed, and the limbs are bent and drawn up to the torso. A compact position is typical for fetuses. Many newborn mammals, especially rodents, remain in a fetal position well after birth.
They are referred to as upright birth positions. [3] Understanding the physical effects of each birthing position on the mother and baby is important. However, the psychological effects are crucial as well. Knowledge about birthing positions can help mothers choose the option they are most comfortable with.
