Klemt AS, et al. - Researchers sought the role of the maternal pelvis, assessed by MRI pelvimetry in nulliparous women expecting a term fetus in breech presentation, to predict a successful and safe vaginal birth. They performed monocentric and anonymized cohort study enrolling 367 nulliparous women with breech presentation at 39⁺⁰ to 41⁺⁰ weeks of gestation during a period of 8 years at the University Women's Hospital in Frankfurt/Main. Standard MRI imaging was done to obtain pelvic measurements. The obstetric conjugate, the pubic angle and the distance between the ischial tuberosities (intertuberous distance), is noted to be correlated with the rate of vaginal deliveries in nulliparous women at term and hence can be used as a useful criterion for pre-selection and counseling of women with breech presentation and the desire for a vaginal delivery.
