The authors investigate the changing management based on a score including the prognostic items in a primiparous woman with a breach presentation. The study involved two series: one from 1970 to 1975, including 185 breach position primiparous women before the score was established, and the other, dating from 1982 to 1988, consisting of 145 breach position primiparous women after this score came into use. The use of the score has tripled the number of cesareans but reduced neonatal morbidity. In contrast, the authors note a slight increase in maternal morbidity, related to the increased cesarean rate.
