Occipito posterior presentation

Abnormal position of the baby’s head during birth. With a normal presentation the head has to turn during passage through the birth canal, and as a result the baby ends up with its head against the mother’s pubic bone. This is necessary, because the head cannot pass through the pelvic aperture in an oblique or transverse position, unless the head is very small or the pelvis very large. If this turn is not made, or if the back of the head is turned in the direction of the mother’s sacrum, the position is known as occipito posterior presentation. A narrow pelvis or weak contractions can cause the problem. A decision on what action to take is made on the basis of the cause, the progress of the birth and the condition of the child at the given moment.
