What is the difference between malpresentation and malposition?

Malpositions are abnormal positions of the vertex of the fetal head (with the occiput as the reference point) relative to the maternal pelvis. Malpresentations are all presentations of the fetus other than vertex. The fetus is in an abnormal position or presentation that may result in prolonged or obstructed labour.

What are the causes of malpresentation and malposition?

Common causes of malpresentations/malpositions include: excess amniotic fluid, abnormal shape and size of the pelvis; uterine tumour; placenta praevia; slackness of uterine muscles (after many previous pregnancies); or multiple pregnancy.
