  • Management
  1. See Breech Delivery
  2. General
    1. Evaluate for cause in all Breech Presentation
    2. Consider postural Exercises for patient
      1. Technique 1: Knee chest
        1. Knee-chest position for 15 minutes
        2. Repeat 3 times daily for 5 days

        1. Patient supine with hips elevated 9-12 inches
        2. Perform 10 minute, once to twice daily
        3. Consider pelvic rocking while performing
      3. Questionable efficacy but considered safe
  3. Footling or Incomplete Breech
    1. Cesarean Section
  4. Frank or Complete Breech
    1. Attempt External Cephalic Version
    2. If external version fails
      1. Cesarean Section or
      2. Breech Delivery
