Pelvic stenosis, cephalopelvic asymmetry, soft birth canal obstruction (such as vaginal septum, cervical scar, etc.), abnormal fetal position, fetal abnormalities (such as hydrocephalus, conjoined twins), can occur in the decline of fetal presentation blocked, in order to overcome resistance to cause strong uterine contraction, can lead to uterine rupture.

Improper indication and measurement of oxytocin, or the uterus is too sensitive to oxytocin, can cause the uterus and contraction is too strong. In addition, the uterine rupture may occur due to the constant operation of the child or the obstruction of the decline of fetal presentation. If the cervix is not opened, forceps, fetal head suction, hip traction or hip midwifery are performed, it is likely to cause cervical laceration, and even rupture of the lower uterine segment. Uterine rupture can also be caused by improper operation or forced separation of placenta. Sometimes instrument damage to the uterus can also cause uterine rupture.
