Summaries of the total studies
The difficulty of childbirth is influenced by three factors, namely, the delivering force, the fetus and the birth way. To judge the birth prognosis, to carry the obsteric treatment, and to decide the obstetric operations, these three factors must be carefully examined and such synthetic consideration would decide all obstetric preparations. Recent advances of these obstetric studies are outstanding. Prticulary although the problems of the relation between the bony parturient canal and the fetal compatibility have long been studied, there still remain aspects which should be investigated. We studied the bony parturient canal of a pregnant women morphologically by roentgenology and discussed the relationships between morphological observation, process of delivery and obstetric operation, with index table of the pelvical uterine basis. Following points became clear. 1. Critical level which cause the development of the imbalance between the pelvis and the fetal head. 2. Points we must be cautions about in observation of delivery process. These data are valuable for the judgment of parturition prognosis and for the decision of the obstetric treatment.
