[Changing fetal position through maternal posture].
The fetal position of 249 cases in their late pregnancy was detected by ultrasound. The results showed that the position of fetal spine tended to lie on the same side as mother's posture during bedrest just before examination. Fetal posterior or transverse spinal position was prone to occur when mother was on her supine position. The fetal cephalic presentation did not correspond entirely with the fetal spinal position. Eighty of the 249 cases presenting fetal spinal posterior or transverse position were chosen at random and corrected by Sims' or hand-knee posture. The better results were obtained especially by the latter. The success rate of correction by maternal posture was affected by the engagement of fetal head and the volume of amniotic fluid. The mechanism of hand-knee posture was discussed. The result indicated that maternal posturing is a clinically valuable procedure. It may be done during pregnancy or in labor to prevent fetal malpresentation.

[Improved cephalic version: a report of 669 cases].
From October 1986 to March 1988, 669 women of 30-40 weeks gestation with breech presentation subjected to improved cephalic version were presented. Using the Doppler sound detector to screen out contraindication, external cephalic version and/or bimanual cephalic version were done one hour after oral administration of 4.8 mg Salbutamol (relaxant of uterine). 647 cases out of 669 gravidae (96.71%) turned out to be successful. This procedure seems to be a simple, save and effective may to lower the incidence of breech presentation and cesarean section rate as well as the perinatal mortality rate of breech presentations.
