Causes of Abnormal Fetal Position

The main causes of fetal malposition include the following points: 1. Polyhydramnios: When there is excessive amniotic fluid, the fetus has increased room for movement within the uterine cavity, making fetal position unstable and leading to malposition. 2. Abnormal uterine shape: Uterine developmental defects or abnormalities (such as unicornuate uterus, bicornuate uterus, etc.) alter the uterine shape, limiting the normal growth space for the fetus and increasing the risk of fetal malposition. 3. Pelvic abnormalities: A narrow pelvis or pelvic inlet may obstruct fetal head descent, potentially causing fetal malposition. 4. Multiple gestation: In cases of multiple pregnancies, limited uterine space may cause fetal crowding, resulting in abnormal fetal positions. 5. Fetal factors: Fetal macrosomia, congenital malformations, or nuchal cord may also affect fetal position. Pregnant women should undergo regular prenatal examinations to detect and correct fetal malposition promptly, ensuring safe delivery.
