title: Assessment of the predictive value of X-ray pelvimetry and biparietal diameter in cephalopelvic disproportion.
abstract: The value of X-ray pelvimetry and ultrasonic measurement of the biparietal diameter for trial of labor prognosis was assessed in 172 healthy primiparas with suspected cephalopelvic disproportion. A decision diagram which is able to correctly predict 50% of the cesarean sections without increasing the number of unnecessary cesarean sections is proposed. In addition, the study confirms the superfluity of X-ray pelvimetry in cases of high station of the fetal head at the end of pregnancy.
