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 be possible.

Fetal Presentation, Position, and Lie (Including Breech Presentation)
Fetal lie: Relation of the fetus to the long axis of the uterus; longitudinal, oblique, or transverse. Normal fetal lie is longitudinal, normal presentation is vertex, and occiput anterior is the most common position. Abnormal fetal lie, presentation, or position may occur with. Fetopelvic disproportion (fetus too large for the pelvic inlet)
The evolution of fetal presentation during pregnancy: a retrospective
We analyzed the frequencies of four types of fetal lie/presentation at each gestational week, which are usually described in fetal ultrasound reports as longitudinal lie cephalic (LLCP) or breech (LLBP) presentations, non-longitudinal lie (NLL, transverse or oblique) and variable lie (VL, changes occurring during the examination).
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.
Abnormal Fetal Lie and Presentation
The most common relationship between fetus and mother is the longitudinal lie, cephalic presentation. A breech fetus also is a longitudinal lie, with the fetal buttocks as the presenting part. ... Fetal heart rate patterns, particularly in the second stage of labor, may have pronounced variable decelerations. In breech labor and delivery ...
Presentation and Mechanisms of Labor
A fetus can be in an unstable or variable lie when the head is completely unengaged and floating. This situation is seen mostly in cases of severe polyhydramnios and prematurity. ... In addition to the fetal lie, presentation, and position, the level or station of the presenting part in the maternal pelvis is an important factor in the labor ...
Breech Presentation, Unstable Lie, Malpresentation, and Malpositions
High-Risk Pregnancy: Management Options - June 2024. Introduction. The concepts of breech presentation, unstable lie, malpresentations, and malposition have not changed for many years but the diagnostic tools and management options change periodically as new management techniques are developed and the evidence for their use improves.
Evidence‐based Obstetrics and Gynecology
In early pregnancy fetuses have a variable lie within the uterus. As the pregnancy approaches the latter part of the third trimester, the majority of singleton pregnancies have a longitudinal lie and the fetus enters the pelvis with a cephalic presentation. Transverse lie, compound presentation, face presentation, and brow presentation together ...
Ultrasound determination of fetal lie and presentation
The fetal presentation describes the fetal part that is lowest in the maternal abdomen. In case of labor, it is the lowest fetal part in the birth canal. Many fetal presentations are possible: Cephalic presentation: the fetal head is the lowest fetal part. This is by far the most common presentation at term of pregnancy and in labor.
Abnormal Presentation
Fetal presentation means the part of the fetus that is "presenting" at the cervix: Cephalic presentation means head first. ... Whenever a fetal transverse lie is encountered near term or in labor, evaluate the patient carefully with ultrasound to determine if there are any predisposing factors, such as a placenta previa or pelvic kidney that ...

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. ... In a transverse lie, the baby is lying horizontally in your uterus and may be facing up toward your head or down toward your feet. Babies settle this way less than ...
Longitudinal ultrasound assessment of fetal presentation: a ...
By 38+ weeks, 54 persisted as either a breech or a transverse lie. Thus, an abnormal presentation in the early trimester carries a 22.2% chance of persisting at term. Continuance of abnormal presentation at each subsequent week of the third trimester increased the risk of a Caesarean delivery at term. Conversely, in only six cases, a cephalic ...

Variation in fetal presentation
breech presentation: fetal rump presenting towards the internal cervical os, this has three main types. frank breech presentation (50-70% of all breech presentation): hips flexed, knees extended (pike position) complete breech presentation (5-10%): hips flexed, knees flexed (cannonball position) footling presentation or incomplete (10-30%): one ...
PLD.23 Management of transverse and unstable lie at term
Aims To determine current practice and outcomes in women admitted to antenatal ward with diagnosis of transverse or unstable lie. Background Fetal lie (other than longitudinal) at term may predispose to prolapse of cord or fetal arm and uterine rupture. Local guidelines recommend admission at 37+0 (RCOG guidelines after 37+6 weeks) but give no specific recommendations regarding further management.
Management of unstable and non-longitudinal lie at term in contemporary
We have observed that there is significant variation in practice and a lack of published evidence on the management of unstable/transverse/oblique lie at term in the modern obstetric practice. The RCOG Green-top Guideline No.50 recommends elective admission after 37 + 0 weeks gestation and immediate admission with signs of labour or rupture of membranes (SROM) to reduce risk of cord prolapse [1].
Fetal Presentation, Position, and Lie (Including Breech Presentation)
Variations in fetal presentation, position, or lie may occur when The fetus is too large for the mother's pelvis (fetopelvic disproportion). The uterus is abnormally shaped or contains growths such as fibroids Uterine Fibroids A fibroid is a noncancerous tumor of the uterus that is composed of muscle and fibrous tissue.
Malpresentation, Abnormal lie and Position Including Unstable lie
Abnormal presentation occurs when the fetus presents in any other manner other than vertex such as breech, face, brow and shoulder presentations. Lie: is the relationship between the long axis of the fetus and the long axis of the mother. Fetal lie can be longitudinal, transverse or oblique. Position: is the relationship of a denominator in the ...

What Is a Fetal Lie and Its Types?
1) Normal Fetal Lie- This position is ideal for labor and baby delivery. In this position, the baby is head-down with the chin tucked into its chest. The back of the head is positioned as it is ready to enter the pelvis. The baby is facing the mother's back. This position is called cephalic presentation, and most babies settle in this position ...
