摘　　要：目的 :观察耻骨联合长度及骨盆出口前后径与头位难产的关系。方法 :将患者分为头位难产组 116例和自然分娩组 116例 ,分别测量身高、体重、腹壁厚度、耻骨联合长度、出口前后径等骨盆径线 ,详细记录产程并绘制产程图 ,记录分娩方式、新生儿体重、B超判断胎方位并测量胎儿双顶径。结果 :2组胎头衔接情况相似 ,头位难产组耻骨联合长度明显较自然分娩组长 ,相反 ,出口前后径则较小 ,其他各项比较无明显差异。结论 :耻骨联合过长及出口前后径较小与头位难产有关 。Aim: To explore the relationship of length of the arcuate pubic ligament and the anteroposterior diameter of the pelvic outlet to dystocia in cephalic presentation. Methods: Subjects with dystocia in cephalic presentation(116 cases,group 1) and subjects of normal delivery in ward at the same duration (116 cases, group 2) were selected. Parameters below were measured or recorded: body height, body weight, thickness of abdominal wall, length of the arcuate pubic ligament , anteroposterior diameter of the pelvic outlet, the labor curve, types of labor, newborn weight, fetal head position and fetal biparietal diameter. Results: Presentation flexion in group 1 was similar to that in group 2. The arcuate pubic ligament in group 1 was longer than that in group 2. On the contrary, anteroposterior diameter of the pelvic outlet was shorter. There were no significant differences in other parameters between group 1 and 2. Conclusion: The results suggest that length of the arcuate pubic ligament and anteroposterior diameter of the pelvic outlet is ralated to dystocia in cephalic presentation and it is necessary to be measured for preventing dystocia in cephalic presentation.
