title: [Value of radiographic studies on the cervix uteri and internal uterine orifice with reference to irregular pregnancies (abortus--premature labor)].
abstract: The research concerning a decrease of premature births in the context of the efforts to reduce infant mortality resources an improvement of our knowledge about the causes of preterm delivery. This publication bases on more than 1000 hysterosalpingographies in order to prove the assumed causality between cervical insufficiency, cervix dilation, and the angle between the cervix and the corpus uteri, and uterushypoplasia. The influence of these facts dependent on menstrual rhythm and related to parity, especially the habitual form, is stated by numerical data. Concerning a retrospective analysis of abortions and premature births the x-ray photography of the uterus makes important statements possible and renders a specific and substantiate prophylactic therapy during the following pregnancies feasible.
