Brief introduction of abnormal fetal position

Abnormal fetal position is one of the common factors causing dystocia. During delivery, occipital anterior position (normal fetal position) accounts for about 90%, while abnormal fetal position accounts for about 10%, among which abnormal fetal head position is the majority, and there are persistent occipital transverse position and persistent occipital posterior position due to obstruction of fetal head rotation in pelvic cavity; There are face exposure and forehead exposure with different degrees of extension due to poor flexion of fetal head; There are also high straight position, front uneven inclination position, etc., accounting for about 6% ~ 7% in total. Abnormal hip presentation accounts for about 3% ~ 4%, and shoulder presentation is rare. In addition, there is compound presentation. In the process of delivery, the fetal head is connected in occipital posterior position or occipital transverse position. In the process of descent, the occipital part of the fetal head can turn forward by 135 or 90 due to strong uterine contractions, and turn into occipital anterior position for natural delivery. If the occipital bone of the fetal head can't turn forward continuously, and it is still located behind or on the side of the maternal pelvis until the late delivery, which makes delivery difficult, it is called persistent occipito posterior position or persistent occipitotransverse position.
