Objective To study different measurements of the humerus for the determination of sex Study design A cross-sectional study Place and duration of study The Anatomy Department of Nishtar Medical University and Hospital from June 1, 2018, to May 31, 2019. Methodology Six measurements, including maximum length of the humerus (MLH), maximum diameter of the head of the humerus (MDH), vertical diameter of the head of the humerus (VDH), transverse diameter of the head of the humerus (TDH), epicondylar breadth (EB), and condylar breadth (CB) were calculated for 122 male humeri and 52 female humeri. These variables were compared between both genders using the student's t-test. Wilks' lambda test was applied. The demarking point of all these variables was defined as the average of the means of male and female measurements. Correctly identified cases were calculated in the male group, the female group, and the whole study group. Data analysis was done in SPSS v.23.0 (IBM Corp, Armonk, NY). P>0.05 was statistically insignificant. Results The differences of MLH, MDH, VDH, TDH, EB, and CB were statistically significant between both the genders (p<0.001). The accuracy of MLH was 85% in the total population. The accuracy of MDH, VDH, and TDH was 76%, 85%, and 76% in the total population, respectively. EB and CB correctly identified 75% and 78% of all the bones. Conclusion This study shows that maximum humeral length and the vertical diameter of the humeral head are the two most important measurements with the highest accuracy for the determination of gender from the skeletal remains of the human body in the South-East Asian population.
目的 研究用于性别判定的不同肱骨测量方法 研究设计 横断面研究 研究地点和时间 2018年6月1日至2019年5月31日在尼什塔尔医科大学及医院解剖学系。 方法 对122例男性肱骨和52例女性肱骨计算六项测量值，包括肱骨最大长度（MLH）、肱骨头最大直径（MDH）、肱骨头垂直直径（VDH）、肱骨头横径（TDH）、髁上宽度（EB）和髁宽度（CB）。使用学生t检验比较这两个性别之间的这些变量。应用威尔克斯lambda检验。所有这些变量的分界点定义为男性和女性测量值均值的平均值。计算男性组、女性组和整个研究组中正确识别的病例数。在SPSS v.23.0（IBM公司，纽约州阿蒙克）中进行数据分析。P>0.05为无统计学意义。 结果 两性之间MLH、MDH、VDH、TDH、EB和CB的差异具有统计学意义（p<0.001）。总体人群中MLH的准确率为85%。总体人群中MDH、VDH和TDH的准确率分别为76%、85%和76%。EB和CB正确识别了所有骨骼的75%和78%。 结论 本研究表明，在东南亚人群中，从人体骨骼遗骸判定性别时，肱骨最大长度和肱骨头垂直直径是两项最重要且准确率最高的测量指标。
