For a period of 44 months 87 deliveries were analyzed by roentgenological pelvimetry, performed by a method, improved by the authors (1982). The relative part of pregnant women with roentgenological pelvimetry was 1.1%. Coefficients of obstetric prognosis were defined in groups retrospectively on the basis of a large material with roentgenological pelvimetry: "compatibility", "conditioned compatibility" and "noncompatibility" as a result of the ratio of the sum of pelvic diameters to the biparietal diameter of the fetus. In the group of "compatibility" of the fetus with the bony pelvis the women, who delivered operatively, had reduced pelvic dimensions with over 0.5 sm in vertex presentations and over 0.3 sm in breech presentations as well as larger weight of the fetus (respectively 4000 and 3500 g). The obstetric prognosis of the groups "compatibility" and "noncompatibility" was exact in 88.9% of the vertex presentations and in 81.5% of the breech presentations.
在44个月的时间里，采用作者改进的方法（1982年）对87例分娩进行了X线骨盆测量分析。接受X线骨盆测量的孕妇比例为1.1%。根据大量X线骨盆测量资料，回顾性地确定了各产科预后组：根据骨盆直径总和与胎儿双顶径的比值，分为“相称”、“相对相称”和“不相称”。在胎儿与骨盆相称组中，剖宫产的产妇骨盆尺寸减小，头先露时超过0.5厘米，臀先露时超过0.3厘米，且胎儿体重较大（分别为4000克和3500克）。“相称”组和“不相称”组的产科预后在头先露时的准确率为88.9%，在臀先露时为81.5%。
