Abstract

Context : The bones of the body are the last to pass away after death, next to enamel of teeth. Hence, in establishing the personal identity with respect to sex, age and stature, medico legal experts, anatomists and anthropologists use the skeletal materials for giving their opinion. Sex-dependent differences have been noted in the pelvic bone anatomy, and so differences exist in male and female sacrum. The aim of this study was to collect data regarding morphometric measurements of maximum length and breadth of sacrum and to find out possible variations of sacral index in different individuals in relation to sex. Material and Methods: A Cross-sectional, analytical type of study was conducted in the department of Anatomy, Dhaka Medical College, on 172 (one hundred seventy two) adult human dry sacra of unknown sex. The study samples were distributed in male and female sex groups by discriminant function analysis. All the samples were studied morphologically. Sacral length and breadth were measured with the help of digital slide calipers. Result : The mean sacral index in male and female were 97.88±6.16 % and 112.69±10.17 % respectively. Female has the greater sacral index than male (P<0.001) Conclusion: Sexing of sacrum, by sacral index method is relevant and significant DOI: http://dx.doi.org/10.3329/bja.v11i1.20502 Bangladesh Journal of Anatomy, January 2013, Vol. 11 No. 1 pp 11-14

骶骨指数在孟加拉尸体骶骨性别估计中的意义

背景:人死后，除了牙釉质之外，身体的骨头是最后消失的。因此，在确定性别、年龄和身材方面的个人身份时，医学、法律专家、解剖学家和人类学家利用骨骼材料发表意见。在骨盆骨解剖中已经注意到性别依赖的差异，因此男女骶骨存在差异。本研究的目的是收集有关骶骨最大长度和宽度的形态测量数据，并找出不同个体的骶骨指数在性别方面的可能变化。材料和方法:在达卡医学院解剖学系对172例(172例)性别不明的成人干骶骨进行了横断面分析性研究。通过判别函数分析，将研究样本分为男女两类。对所有样品进行了形态学研究。用数字滑动卡尺测量骶骨长度和宽度。结果:男性和女性的平均骶指数分别为97.88±6.16%和112.69±10.17%。结论:骶骨的性别，通过骶骨指数方法是相关的和重要的DOI: http://dx.doi.org/10.3329/bja.v11i1.20502孟加拉解剖学杂志，2013年1月，Vol. 11 No. 1 pp 11-14
