This paper reports the findings in 22 primigravidae in whom Caesarian section was performed because of impaction of the head in mid-pelvis. 100 women who had normal deliveries served as controls. The routinely-determined external measurements of the pelvis were within the normal range in all women, whereas the distances between symphysis and the 3rd or 5th sacral vertebra were reduced in comparison with the conjugata externa in patients requiring Caesarian section. For an exact diagnosis ultrasound and X-ray pelvimetry was performed post sectionem. A reduced distance between the symphysis and the 3rd or 5th sacral vertebra was ascertained by both methods. Hence, a channel pelvis might be the main reason in these women for standstill in labour. The ultrasound and X-ray pelvimetry results were comparable.
本文报告了22例因胎头嵌顿于中骨盆而行剖宫产的初产妇的研究结果。100例正常分娩的妇女作为对照。所有妇女常规测量的骨盆外测量值均在正常范围内，而与剖宫产患者的外结合径相比，耻骨联合与第3或第5骶椎之间的距离减小。为了准确诊断，剖宫产后进行了超声和X线骨盆测量。两种方法均确定耻骨联合与第3或第5骶椎之间的距离减小。因此，骨盆狭窄可能是这些妇女产程停滞的主要原因。超声和X线骨盆测量结果具有可比性。
