摘　　要：目的 探讨拉萨藏族女性骨盆径线正常值。方法 选取中国人民解放军西藏军区总医院2016年1月~2019年12月于放射科行盆腔CT检查的藏族妇女为研究对象,排除不符合要求者,有效样本96例,年龄介于22~65岁,平均年龄(46.06±11.42)岁。应用Mimics19.0软件构建出骨盆的数字化三维模型,并测量入口横径、入口前后径、中骨盆横径、中骨盆前后径、出口横径、出口前后径、骶耻内径、骶骨长度和耻骨联合高度。不同年龄段间比较选用方差分析,年龄与骨盆各径线值之间进行Pearson相关性分析。结果 拉萨藏族正常女性骨盆入口横径为(132.08±6.15)mm,入口前后径(112.44±9.43)mm,中骨盆横径(107.30±8.70)mm,中骨盆前后径(129.06±7.73)mm,出口横径(123.02±12.08)mm,出口前后径(118.80±8.87)mm,骶耻内径(127.49±9.80)mm,骶骨长度(102.56±10.88)mm,耻骨联合高度(36.57±4.57)mm。聚类分析显示,拉萨藏族与维吾尔族最接近。结论 拉萨藏族与维吾尔族之间较近的聚类关系,提示藏族与和田地区维吾尔族在古代存在基因交流的可能。拉萨藏族女性骨盆的径线发生了明显改变,更窄的入口前后径、骶骨长度和耻骨联合高度使骨盆越趋变的扁平,越来越不利于自然分娩。Objective To explore the range of normal female pelvic diameter lines in Tibetan nationality.Methods The subjects were Tibetan nationality female who underwent pelvic CT examination in the Radiology Department from January 2016 to December 2019 at the General Hospital of the Tibet Military Region of PLA.Ninty⁃six samples between the ages of 22 and 65 years,with an average age(46.06±11.42)years were recruited.Mimics 19.0 software was used to construct the digital three⁃dimensional model of pelvis,and to measure transverse diameter(TD),obstetric conjugate(OC),interspinous distance(ISD),sagittal midpelvic diameter(SMD),intertuberous distance(ITD),sagittal outlet diameter(SOD),diagonal conjugate diameter(DCD),sacrum length(SL),penal height(PH).Analysis of variance was used to compare different age groups,andPearsoncorrelation analysis was used to analyze the relationship between age and pelvic diameter.Results The linear measurement of TD was(132.08±6.15)mm,OC was(112.44±9.43)mm,ISD was(107.30±8.70),SMD was(129.06±7.73)mm,ITD was(123.02±12.08)mm,SOD was(118.80±8.87)mm,DCD was(127.49±9.80)mm,SL was(102.56±10.88)mm and PH was(36.57±4.57)mm.Cluster analysis showed that Lhasa Tibetans were closest to Uygurs.Conclusion The close clustering relationship between Tibetans and Uygurs in Lhasa suggests that there is a possibility of gene exchange between Tibetans and Uygurs in Hotan area in ancient times.The pelvic diameter of Tibetan women in Lhasa has changed significantly.Narrower OC,SL and PH make the pelvis flat,which is more and more detrimental to natural childbirth.
