[Clinical and x-ray studies on the relationship between interruption of pregnancy and premature labor].

On the basis of the number of premature babies of 1975 the possible interdependence is checked between interruptio of pregnancy and subsequent premature birth and is compared with the dates obtained in 1974. Besides the hysterograms of women with premature birth whose anamnesis indicates an interruptio of pregnancy, are examined with regard to lesions of the cervix demonstrable in roentgenograms. As in the years of 1974 and 1975 the number of premature birth has been approximatively constant we conclude, basing ourselves on the investigations of roentgenograms, that no causal relation may be established between interruptio of pregnancy and premature birth in our material.
