This study was undertaken to determine the baseline pelvic parameters as assessed by computed tomographic (CT) pelvimetry in Nigerian women and to compare the pelvic parameters with those derived from other studies.
The study was carried out in pregnant women at 36 weeks and above referred for routine CT-pelvimetry.
A total of 100 pregnant women at 36 weeks and above referred to the Radiology Department were prospectively recruited for this study, they included women with breech presentation after 36 weeks gestation and women who either had previous lower segment caesarean section for reasons other than confirmed or suspected cephalopelvic disproportion (CPD). The subjects' ages ranged from 24-45 years.
The mean anteroposterior and transverse inlet pelvic diameters were 11.6 cm +/-SD 0.9 and 12.0 +/-SD 0.8 cm respectively. The range of anteroposterior and transverse diameters of the inlet were 8.4 cm-14.0 cm and 10-13.8 cm respectively. The mean outlet diameter was 11.5 cm +/-SD 1.2 cm. The mean bispinous diameter of the pelvis was 10.6 cm +/-SD 0.9 cm. There was significant positive correlation between anteroposterior diameter inlet and outlet as well as the bispinous diameters (1st, 4th - 6th pairs) p<0.001.
here are significant variations in pelvic parameters of Nigerian women when compared with values from other countries of the world. These significant variations are anthropometric in origin.
本研究旨在通过计算机断层扫描（CT）骨盆测量法确定尼日利亚女性的骨盆基线参数，并将这些骨盆参数与其他研究得出的参数进行比较。
该研究针对孕周36周及以上的孕妇进行常规CT骨盆测量。
前瞻性招募了100名孕周36周及以上转诊至放射科的孕妇，包括孕36周后臀位的孕妇以及因非确诊或疑似头盆不称（CPD）以外的原因行过下段剖宫产的孕妇。研究对象年龄在24 - 45岁之间。
骨盆入口前后径和横径的平均值分别为11.6 cm±标准差0.9 cm和12.0±标准差0.8 cm。入口前后径和横径的范围分别为8.4 cm - 14.0 cm和10 - 13.8 cm。出口平均直径为11.5 cm±标准差1.2 cm。骨盆双棘径平均值为10.6 cm±标准差0.9 cm。入口前后径与出口以及双棘径（第1、4 - 6对）之间存在显著正相关（p<0.001）。
与世界其他国家的值相比，尼日利亚女性的骨盆参数存在显著差异。这些显著差异源于人体测量学。
