Fetal Lie is the orientation of the long axis of the fetus and the long axis of the woman. It has three different types the longitudinal lie, transverse lie, and the oblique lie.

Longitudinal Lie

The fetal spine is parallel with the mother’s spine. Usually the fetus is in cephalic or breech presentation.

Transverse Lie

The fetal spin is horizontal or is at a right angle with the mother’s spine. The presenting part of the fetus is the shoulder and delivery is usually caesarian.

Oblique Lie

The fetal spine is diagonal to the mother’s spine. Delivery is by caesarian section if uncorrected.
