A national survey of clinicians’ opinions of rotational vaginal births

Malposition of the fetal head, defined as occiput transverse or posterior positions, occurs in approximately 5% of births. At full cervical dilatation, fetal malposition is associated with an increased risk of rotational vaginal birth. There are three different rotational methods: manual rotation, rotational ventouse or rotational (Kielland's) forceps. In the absence of robust evidence, it is not currently known which of the three methods is most efficacious, and safest for parents and babies.
