[Ultrasound imaging of the symphysis fissure for evaluating damage to the symphysis in pregnancy and postpartum].

In a cross-sectional study of 211 patients with a normal pregnancy the distance of the symphysis was sonographically measured during pregnancy and normal values were evaluated. Physiologically a continuous widening of the symphysis was shown up to 3 mm an average. The sonographical sign of the damage of the symphysis was a deviation in widening and also a difference in height. The value of the sonographic examination is shown in 2 cases with damage of the symphysis and compared to the x-ray picture results.
