Research data show that the incidence rate of the head dystocia accounts for about 10% of the total vaginal delivery and about 70% of the total dystocia, and more than 85% of the head dystocia is caused by abnormal fetal head position. In the labor process, the abnormality of the fetal position can be timely and accurately found and the fetal position can be correctly adjusted, so that most of the dystocia can be avoided, and the diagnosis and the adjustment of the fetal position are necessary basic skills for obstetricians and midwives.
For medical students and beginners such as young obstetricians and midwives, it is easy to understand the degree of expansion and decline of uterine orifice and premature ejaculation through the vagina internal diagnosis, but it is a puzzled matter how to accurately judge the fetal position and correctly adjust the abnormal fetal position.
