Which fetal position is most commonly associated with prolonged labor due to malposition?
Occipito-posterior position
Normal (optimal) labour needs the fetal head to flex and present occipito-anterior, so the smallest head diameter engages the pelvis.
When the occiput points backward (occipito-posterior), the head presents a larger diameter and must rotate 135 degrees to deliver, which prolongs labour and often causes back pain.
Transverse lie and breech presentation are malpresentations rather than malpositions of the vertex, and occipito-anterior is the normal position, not a malposition.
Hence, Occipito-posterior position.
