Abdominal examination (Leopold’s maneuvers)
Vaginal examination during labor
Ultrasound, which is the most reliable method
Which malpresentation is the most dangerous?
Transverse lie is considered the most dangerous malpresentation because vaginal delivery is impossible and there is a high risk of cord prolapse and uterine rupture.

Yes, some malpresentations (especially breech) can be corrected by External Cephalic Version (ECV) after 36–37 weeks, provided there are no contraindications.

Cesarean section is required in:
Transverse lie
Persistent brow presentation
Mentum posterior face presentation
