The most common cause of uterine rupture is separation of previous cesarean hysterotomy scar. Other common predisposing factors to uterine rupture are previous traumatizing operations or manipulations such as curettage, perforation, myomectomy and excessive or inappropriate uterine stimulation with oxytocin.
