The top of the head is the presenting part. This is an uncommon fetal position and a vaginal birth is unlikely.Ĭommonly, this skull diameter is too large to pass through the pelvis. Vertex meets resistance from the cervix, pelvic walls or pelvic. These are sometimes called the mechanisms of labor/labour. Movements 1-3 all have to do with the pelvic inlet - the opening portion of the pelvis, from the baby’s perspective. Brought about by pressure of amniotic fluid, direct pressure of fundus on the fetuss buttocks or head, abdominal muscle contractions, extension and straightening of the fetal body. In this video I discuss the Cardinal Movements of labor/labour. I would summarize of the Cardinal Movements of Labor as: The baby moves down the birth canal, rotating and flexing its head to match the widest opening of the pelvis along the way until it is born. Many fetuses assume this attitude early in labor but convert to complete flexion as labor progresses. Downward movement of the fetal head until it is within the pelvic inlet. This position is commonly called the fetal position. The back is usually arched, which increases the degree of hyperextension. In complete extension, the head and neck of the fetus are hyperextended and the occiput touches the fetus’s upper back. In partial extension, the head of the fetus is extended, with the head pushed slightly backward so that the brow becomes the first part of the fetus to pass through the pelvis during birth. Moderate flexion (aka military position or sinciput), the head of the fetus is slightly flexed but held straighter than in complete flexion. External rotation: occurs as the shoulders engage and descend in maneuvers similar to those of the head. Restitution: after the head is born it rotates (45 degrees) briefly to the position it occupied when it was engaged in the inlet. Is a series of passive movements of the fetus in the passage through the birth canal. Mechanism of labor (cardinal movements): Restitution and External rotation. In complete flexion, the head of the fetus is tucked down onto the chest, with the chin touching the sternum. MECHANISM OF NORMAL LABOUR The series of movements that occur on the head in the process of adaptation during its journey through the pelvis is called mechanism of labor. ![]()
