What is the most common fetal Malpresentation?
Breech presentation is the most common malpresentation, with the majority discovered before labour. Breech presentation is much more common in premature labour. Approximately one third are diagnosed during labour when the fetus can be directly palpated through the cervix.
How many types of fetal presentations are there?
There are three types of face presentation: Mentum anterior (MA): In this position, the chin is facing the front of the mother. Mentum posterior (MP): The chin is facing the mother’s back, pointing down towards her buttocks in mentum posterior position.
What are the types of Malpresentation and malposition?
Types
- fetal malpresentations types include 1,3,4 breech – most common malpresentation; buttocks or feet of fetus are fetal presenting part.
- fetal malposition types include 2,3 occiput posterior – fetal occiput is oriented toward the posterior aspect of the maternal pelvis.
What are the types of fetal position?
What are the types of fetal positioning for birth?
- Occiput anterior (OA) The best fetal position for your baby to be shortly before birth is feet up, head down, facing your back, with their back resting against your belly.
- Occiput posterior (OP)
- Breech position.
- Oblique position.
- Transverse position.
What is fetal lie in pregnancy?
Fetal lie refers to the relationship between the long axis of the fetus with respect to the long axis of the mother. The possibilities include a longitudinal lie, a transverse lie, and, on occasion, an oblique lie. Fetal presentation is a reference to the part of the fetus that is overlying the maternal pelvic inlet.
What is fetal position in pregnancy?
Normally, the position of a fetus is facing rearward (toward the woman’s back) with the face and body angled to one side and the neck flexed, and presentation is head first. An abnormal position is facing forward, and abnormal presentations include face, brow, breech, and shoulder.
What are the types of malposition?
There are different types of malpresentation:
- Breech presentation: A breech presentation is when the baby is lying with their bottom or feet down.
- Transverse lie: A transverse lie is when the baby is lying sideways.
- Oblique lie: The baby’s head is against the mother’s hip, high above the birth canal.
What causes fetal malposition?
Common causes of malpresentations/malpositions include: excess amniotic fluid, abnormal shape and size of the pelvis; uterine tumour; placenta praevia; slackness of uterine muscles (after many previous pregnancies); or multiple pregnancy.
What is normal fetal lie?
What is the difference between fetal malpresentation and malposition?
Fetal Malpresentation and Malposition: Diagnosis and Management Fetal malpresentation and fetal malposition are frequently interchanged; however, fetal malpresentation refers to a fetus with a fetal part other than the head engaging the maternal pelvis. Fetal malposition in labor includes occiput posterior and occiput transverse positions.
What causes a fetus to be malpresented during pregnancy?
Malpresentation may be caused by: 1 having a low-lying placenta 2 having too much or too little amniotic fluid 3 an abnormally shaped uterus 4 problems with the uterus, such as large fibroids More

Which is the most common presentation in a fetus?
The most common presentation is the vertex of the fetal head. If the vertex is not the presenting part, see Table S-12. If the vertex is the presenting part, use landmarks of the fetal skull to determine the position of the fetal head (Fig S-9).
