In obstetrics, a shoulder presentation is a malpresentation at childbirth where the baby is in a transverse lie (its vertebral column is perpendicular to that of the mother), thus the leading part (the part that first enters the birth canal) is an arm, a shoulder, or the trunk.
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.
This causes rapid decompression of the baby's head. In contrast, a baby going through labor in the head-down position usually experiences gradual molding (temporary reshaping of the skull) over the course of a few hours. This sudden compression and decompression in breech birth may cause no problems at all, but it can injure the brain.
Babies are usually born head first. If the baby is in another position the birth may be complicated. In a 'breech presentation', the unborn baby is bottom-down instead of head-down. Babies born bottom-first are more likely to be harmed during a normal (vaginal) birth than those born head-first. For instance, the baby might not get enough oxygen ...
The most common and preferred type of asynclitism is the left occiput anterior asynclitism because the baby's head enters the pelvis in such a way that it minimizes the circumference of how the baby exits the body as much as possible. In this type of asynclitism, it allows the fetus to be in the most efficient position.
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.
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).

Short ribs at the first lumbar vertebra, which is thus a transitional vertebra, since lumbar vertebrae normally do not have ribs attached to them. Transitional vertebrae have the characteristics of two types of vertebra. The condition usually involves the vertebral arch or transverse processes. It occurs at the cervicothoracic, thoracolumbar ...
