There are three types of breech presentation, as illustrated in the Figure below. They are:

• Complete breech is characterised by flexion of the legs at both hips and knee joints, so the legs are bent underneath the baby.
• Frank breech is the commonest type of breech presentation, and is characterised by flexion at the hip joints and extension at the knee joints, so both the baby's legs point straight upwards.
• Footling breech is when one or both legs are extended at the hip and knee joint and the baby presents 'foot first'.
