Pelvic prelying

AbdUlghani Allahham
Pelvic prelying: sa delivery of a baby which is so positioned in the uterus that the buttocks or feet are delivered first.
Buttock prelying: when the baby's buttocks or feet or both are in place to come out first during birth. Breech presentation is often determined by
fetal ultrasound at the end of pregnancy.
Pure buttock: the legs of the fetus are bent at the hip joints, the knees are straightened and pressed to the stomach
The mixed buttock prelying : the buttocks and feet are adjacent, the hips are bent, the knees are also bent.
Foot prelying : both or one leg extended to the entrance to the birth canal
Full foot prelying : both legs (feet) of the fetus are presented, while both legs are unbent at the hip joints
Incomplete foot prelying : the buttocks and one of the legs (feet) of the fetus are presented. In this case, one leg is unbent at the hip and knee
Umbilical cord loss at pelvic prelying : when the umbilical cord comes out of the uterus with or before the presenting part of the baby.
Reduction of the sizes and lowering of the pelvic end: its when Reduction in size and lowering of the pelvic end in woman.
Internal turn of buttocks : consists in the fact that when moving from a wide part of the pelvis to a narrow one, the buttocks turn into a straight
size of the pelvis.
insertion and the eruption of the buttocks : After the eruption of the anterior buttock, the ilium of the fetus rests against the symphysis
(fixation point) .
Lateral flexion of the trunk : There is a strong lateral flexion of the fetal body, then the posterior buttock is born.
Manual guide(help) method by Tsovyanova when buttock prelying : its breech presentation according to the method of Tsovyanov.
Manual guide(help) method by Tsovyanova when foot prelying: its Manual aid for foot presentation according to the method of Tsovyanov.
Extraction of pelvic end: Extraction of the fetus by the pelvic end is a delivery operation in which the fetus is removed from the birth canal
using manual techniques.
Extensor presentation of the fetal head : the head is inserted into the entrance to the pelvis unbent.
eruption of the head during breech presentation: its when eruption of the head happen during breech presentation.
Extension of the head in breech: the first degree of extension of the head, in which the large fontanelle becomes the leading point, and the
plane of the large segment passes through the average oblique size of the fetal head, equal to 10 cm (circumference 33 cm).
Frontal prelying of the fetus: Characterized by the fact that the wire point is the forehead. The head passes all the planes of the pelvis with a
large oblique size. This is the largest size (from the chin to the outer occipital protrusion), it is 13-13.5 cm.
heads at frontal prelying: its when Embedding of the head in frontal presentation.
Facial (Obverse) prelying: Third degree of extension. Wired point chin. The head passes the birth canal in a vertical size (from the hyoid bone
to the middle of the large fontanel, which is 9.5-10 cm).
Head configuration for facial previa: the fetal head and neck are hyperextended, causing the occiput to come in contact with the upper back
of the fetus while lying in a longitudinal axis. The presenting portion of the fetus is the fetal face between the orbital ridges and the chin.
Rear asynclitism : the posterior parietal bone descends first into the pelvis, the sagittal suture is deflected anteriorly to the womb.
Front asynclitism :the sagittal suture is close to the sacrum, and the anterior parietal bone descends first into the plane of the entrance of the
small pelvis, the leading point is located on it.
