Breech presentation occurs when the fetal pelvis or lower extremities engage the maternal pelvic inlet.
Frank breech: the hips are flexed with extended knees bilaterally.
Complete breech: both hips and knees are flexed.
Footling breech: one or both legs are extended below the level of the buttocks.
Risk factors: Preterm gestation, previous breech presentation, uterine abnormality, placental abnormality, amniotic fluid abnormalities (polyhydramnios, oligohydramnios), fetal anomaly, female sex, older maternal age.
Diagnosis: Physical examination and ultrasound.
Treatment:In most cases, spontaneous version may occur at any time before delivery, even after 40 weeks of gestation. If not: External cephalic rotation before labor, with a trial of labor if the version is successful and cesarean delivery if unsuccessful.
