Fetus or newborn affected by malpresentation before labour (Q45536)

Malpresentations are all presentations of the fetus other than the vertex, and includes breech, transverse, shoulder, compound, face, and brow presentations. They may pose risks to the fetus and mother and may necessitate operative vaginal or caesarean delivery, or other interventions to accomplish delivery. Breech presentation, the most common malpresentation, results when the fetal buttocks, legs, feet, or a combination of these presents first into the maternal pelvis.
