Fetal Presentation, Position, and Lie (Including Breech Presentation
Head first (called vertex or cephalic presentation) Facing backward (occiput anterior position) Spine parallel to mother's spine (longitudinal lie) Neck bent forward with chin tucked. Arms folded across the chest . If the fetus is in a different position, lie, or presentation, labor may be more difficult, and a normal vaginal delivery may not ...
Fetal Presentation, Position, and Lie (Including Breech Presentation
In breech presentation, the presenting part is a poor dilating wedge, which can cause the head to be trapped during delivery, often compressing the umbilical cord. For breech presentation, usually do cesarean delivery at 39 weeks or during labor, but external cephalic version is sometimes successful before labor, usually at 37 or 38 weeks.
Your Guide to Fetal Positions before Childbirth
Head Down, Facing Down (Cephalic Presentation) This is the most common position for babies in-utero. In the cephalic presentation, the baby is head down, chin tucked to chest, facing their mother's back. This position typically allows for the smoothest delivery, as baby's head can easily move down the birth canal and under the pubic bone ...
Fetal Positions For Birth: Presentation, Types & Function
Occiput or cephalic anterior: This is the best fetal position for childbirth. It means the fetus is head down, facing the birth parent's spine (facing backward). Its chin is tucked towards its chest. The fetus will also be slightly off-center, with the back of its head facing the right or left. This is called left occiput anterior or right ...
Fetal presentation before birth
Frank breech. When a baby's feet or buttocks are in place to come out first during birth, it's called a breech presentation. This happens in about 3% to 4% of babies close to the time of birth. The baby shown below is in a frank breech presentation. That's when the knees aren't bent, and the feet are close to the baby's head.
Delivery, Face and Brow Presentation
The term presentation describes the leading part of the fetus or the anatomical structure closest to the maternal pelvic inlet during labor. The presentation can roughly be divided into the following classifications: cephalic, breech, shoulder, and compound. Cephalic presentation is the most common and can be further subclassified as vertex, sinciput, brow, face, and chin.
Your baby in the birth canal
Cephalic presentation occurs in about 97% of deliveries. There are different types of cephalic presentation, which depend on the position of the baby's limbs and head (fetal attitude). If your baby is in any position other than head down, your doctor may recommend a cesarean delivery. Breech presentation is when the baby's bottom is down ...
Cephalic presentation
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). All other presentations are abnormal (malpresentations ...
Physiology of Normal Labor and Delivery: Part I and II
The normal fetal attitude when labor begins is with all joints in flexion. Lie : This refers to the longitudinal axis of the fetus in relation to the mother's longitudinal axis (i.e., transverse, oblique, or longitudinal (parallel). Presentations: This describes the part on the fetus lying over the inlet of the pelvic or at the cervical os.
Presentation and Mechanisms of Labor
The cephalic presentation can be further categorized based on the degree of flexion of the fetal head: ... The evolutionary factors are shown in the vertical axis of the diagram, illustrating the transition from the longitudinal oval (anthropoid) to the flat (platypelloid) pelvis. The transverse axis shows the sexual factors, illustrating the ...
Fetal presentation: Breech, posterior, transverse lie, and more
Fetal presentation, or how your baby is situated in your womb at birth, is determined by the body part that's positioned to come out first, and it can affect the way you deliver. ... This is called an external cephalic version, and it has a 58 percent success rate for turning breech babies. For more information, ...
Chapter 10: Normal Mechanisms of Labor
The lie is longitudinal. The long axis of the fetus is parallel to the long axis of the mother. The head is at or in the pelvis. The back is on the left and anterior and is palpated easily except in obese women. The small parts are on the right and are not felt clearly. The breech is in the fundus of the uterus.

Sonographic evaluation of the fetal head position and attitude during
Cephalic presentation can be defined as a condition where the fetus is in longitudinal lie and the head enters the pelvis first. The fetal vertex is the portion of the head lying in the midline between the 2 fontanels, and vertex presentation is the most favorable presentation for a vaginal delivery because it features a sharp flexion of the ...
Leopold Maneuvers
In the cephalic presentation, the hand is placed flat on the pubic symphysis, and the palpation could delineate the fetal head portion that can be reached above the pelvic inlet. Using the rule of fifths, the distance between the base and vertex of the fetal head is divided into five equal parts. Each fifth corresponding to 2 cm or ...
Vertex Presentation: Position, Birth & What It Means
Vertex Presentation. A vertex presentation is the ideal position for a fetus to be in for a vaginal delivery. It means the fetus is head down, headfirst and facing your spine with its chin tucked to its chest. Vertex presentation describes a fetus being head-first or head down in the birth canal.

Fetal Position
Fetal position reflects the orientation of the fetal head or butt within the birth canal. Anterior Fontanel. The bones of the fetal scalp are soft and meet at "suture lines." Over the forehead, where the bones meet, is a gap, called the "anterior fontanel," or "soft spot." This will close as the baby grows during the 1st year of life, but at ...
Compound Presentations
A presentation is compound when there is prolapse of one or more of the limbs along with the head or the breech, both entering the pelvis at the same time. Footling breech or shoulder presentations are not included in this group. Associated prolapse of the umbilical cord occurs in 15 to 20 percent of cases.
Management of breech presentation
Introduction. Breech presentation of the fetus in late pregnancy may result in prolonged or obstructed labour with resulting risks to both woman and fetus. Interventions to correct breech presentation (to cephalic) before labour and birth are important for the woman's and the baby's health. The aim of this review is to determine the most ...
Abnormal Fetal lie, Malpresentation and Malposition
Abnormal Fetal Lie. If the fetal lie is abnormal, an external cephalic version (ECV) can be attempted - ideally between 36 and 38 weeks gestation. ECV is the manipulation of the fetus to a cephalic presentation through the maternal abdomen. It has an approximate success rate of 50% in primiparous women and 60% in multiparous women.
