Transverse lie is a term used in obstetrics to describe a fetal position where the baby lies sideways in the uterus, rather than in the typical head-down position. This position can complicate labor and delivery, as it may prevent the baby from passing through the birth canal properly. In a transverse lie, the baby's shoulder or back is positioned against the mother's cervix. This situation can occur at any point during pregnancy but is more common in the later stages. If the baby remains in this position close to the due date, healthcare providers may consider options like a cesarean section for safe delivery.
