Of the 4,529 women delivered of infants at The John Hopkins Hospital during 1976 and 1977, 212 (5%) had roentgenographic pelvimetry. An analysis of a subgroup of 142 single vertex pregnancies with radiographic pelvimetry during this two-year period is presented. The cesarean section rate was 40% among patients selected for roentgenographic pelvimetry whose pelvis was found to be adequate. Vaginal delivery in women with a pelvis radiographically shown to be small was accomplished in 27% of patients with failure to progress in labor and in 22% of the patients with a fetus in the floating vertex presentation. Patients with a small pelvis who delivered vaginally had significantly smaller infants than those delivered by cesarean section (2,785 +/- 399 gm vs 3,146 +/- 433 gm). The only significant difference in pelvic measurements between these two groups occurred in the AP diameter of the inlet (11.5 +/- 1.1 cm vs 10.5 +/- 1.0 cm). Roentgenographic pelvimetry of single pregnancies as evaluated in this study appears to have limited clinical usefulness.
1976年至1977年期间，在约翰霍普金斯医院分娩婴儿的4529名女性中，有212名（5%）接受了X线骨盆测量。本文呈现了对这两年期间142例单胎头位妊娠且进行了X线骨盆测量的亚组分析。在因X线骨盆测量而入选且骨盆被认为足够的患者中，剖宫产率为40%。骨盆X线显示小骨盆的女性中，产程无进展的患者有27%经阴道分娩，胎头浮动的患者有22%经阴道分娩。经阴道分娩的小骨盆患者所产婴儿明显小于剖宫产患者所产婴儿（2785±399克 vs 3146±433克）。这两组之间骨盆测量的唯一显著差异出现在入口前后径（11.5±1.1厘米 vs 10.5±1.0厘米）。本研究中评估的单胎妊娠X线骨盆测量似乎临床实用性有限。
