What are the four main types of breech presentations?

The four main types of breech presentations are classified as frank breech, full (or complete) breech, footling breech, and transverse.

In a frank breech presentation, the baby's buttocks are positioned to come out first, with the legs extended straight up in front of the body. This is the most common type of breech presentation.

A full breech presentation involves the baby’s buttocks positioned downwards but with the legs folded at the knees, somewhat like a seated position.

In the footling breech presentation, one or both feet are positioned to come out first, which can present a greater risk during delivery as the baby is not in a typical presenting position.

Transverse presentations, on the other hand, involve the baby lying sideways in the uterus and are not classified as breech presentations. The other options do not accurately reflect the categories of breech presentations, which are specifically concerned with the positioning of the baby’s body parts relative to the birth canal.
