Podalic version is an obstetric procedure wherein the fetus is turned within the womb such that one or both feet present through the cervix during childbirth. It is used most often in cases where the fetus lies transversely or in another abnormal position in the womb. In modern medicine, abnormal lies are increasingly delivered via Caesarean ...
In obstetrics, a cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal).

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.
In the third period, from the 36th gestational week onward, the incidence of cephalic and breech presentations remain stable, i.e. breech presentation around 3–4% and cephalic presentation approximately 95%. In the general population, incidence of breech presentation at preterm corresponds to the incidence of breech presentation when birth ...
External cephalic version (ECV) is a process by which a breech baby can sometimes be turned from buttocks or foot first to head first. It is a manual procedure that is recommended by national guidelines for breech presentation of a pregnancy with a single baby, in order to enable vaginal delivery.
Shoulder presentations are uncommon (about 0.5% of births) [1] since, usually, toward the end of gestation, either the head or the buttocks start to enter the upper part of the pelvis, anchoring the fetus in a longitudinal lie. It is not known in all cases of shoulder presentation why the longitudinal line is not reached, but possible causes ...
Leopold's maneuvers. 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.
He revived the practice of podalic version, and showed how even in cases of head presentation, surgeons with this operation could often deliver the infant safely, instead of having to dismember the infant and extract the infant piece by piece.
