. During 1969–1974 six hundred and forty‐nine external versions were attempted during the last trimester on 491 mothers with fetal malpresentation. the procedure was monitored with ultrasound in 1969–1974. Most of attempts (70.0%) were made during the 32nd–36th weeks. the final version rate after one or more attempt was 76.2%, being lower (67.0%) in nulliparous than parous women (84.6%). the incidence of breech presentation at birth decreased from 4.5 to 2.9% ( p <0.001). the most serious complication was one premature labor but the infant survived. the perinatal mortality was 2.0% and, after excluding abnormal infants, 0.8%. the combination of external version and the use of ultrasound is a safe method which avoids hazardous vaginal breech delivery and is recommended in obstetric practice.
