Sixty-six premature breech deliveries were studied retrospectively. Forty-eight patients were permitted a trial of labor, 47 of whom ultimately delivered vaginally. Eighteen patients underwent cesarean section as soon as possible after their arrival at the delivery suite. When Apgar scores, perinatal mortality rates, cord prolapse, and entrapment of the aftercoming head are considered, cesarean section is probably the safer course of management for the patient with a footling breech infant, especially when the infant weighs 1500 g or less. However, the data indicate that a trial of labor can be safely undertaken in the presence of a premature frank or complete breech presentation.
