Separation of the pubic symphysis, a complication that occurs in some women in late pregnancy, is caused by over-sensitivity to relaxin in late pregnancy. Women will secrete relaxin during late pregnancy to relax the ligamentous joints of the pelvis, thus facilitating labor. If individual women are over-sensitive to relaxin, it will result in separation of the pubic symphysis, which is manifested as pain in the pubic symphysis and even inability to walk. There is no good treatment for pubic symphysis separation, you can tie the pelvis tightly, but this method is rarely used clinically because of the possibility of adverse effects on the fetus, generally have to wait until 1-2 months after the delivery will gradually get better, the pubic symphysis separation does not affect the normal delivery, as long as you can take the position of labor, bladder stone position, that is, you can have a normal delivery.
