[Prenatal trauma of newborns from labor with pelvic presentation in the I Obstetric Clinic Medical Academy in Wrocław in the years 1946-1990].

The analysis of 2191 labours with pelvic presentation indicated that most perinatal traumas of newborns occurred after manual extraction of the fetus, and least frequent injuries were in children delivered by caesarean section. Within the period of 45 years (1946-1990) a statistically significant decrease occurred of the number of perinatal trauma of newborns which was proportional to an increase of the number of labours terminated with caesarean section.
