摘要

In the vast majority of deliveries near term the fetus presents bythe head, with the best fit into the lower pelvis in theoccipito-anterior position. However, although the head is presenting,it may be not in an occipito-anterior but in an occipito-posterior ortransverse position. In a few cases the head is grossly deflexed sothat the brow or even the face can present. In other instances, it isnot the head that is at the lower pole Of the uterus but thebuttocks, or breech (from the old English Brec-breeches or buttocks).
