Frank breech is most common in full-term deliveries and presents with both hips flexed and both knees extended. In a complete breech, both hips and knees are flexed. In both of these, the infant’s buttocks are the usual presenting body part at the perineum. A footling breech has one or both legs extended below the buttocks and a foot is the presenting part. Footling presentation is seen in up to half of all preterm deliveries. Breech deliveries carry a much higher neonatal mortality rate than normal deliveries. Complications of breech delivery include umbilical cord prolapse, nuchal arm obstruction, and difficulty in delivery of the head.
