Anthropologists and forensic pathologist determine the sex of skeletons by analyzing quantitative and qualitative characters in the bone remains. Generally, the skull and os coxae are the elements most used, but they are not always preserved. In such cases, the investigator needs to have available other techniques based on different remains. The aim of the present work is to develop and describe discriminating functions for sex determination in a recent Spanish population using metacarpal morphology. A sample of bones corresponding to a contemporary Spanish population deposited at the Complutense University of Madrid (UCM) was analyzed. This sample comprised 697 metacarpals, corresponding to 79 adult individuals (37 men and 42 women). These allowed us to obtain 120 unifactorial discriminant functions. We selected the 10 equations, one for each metacarpal from both hands, that provided the best sexual discrimination. The correct sex classification rank progressed from 81%, for right (R) metacarpals IV and V, to 91%, for left (L) metacarpal II. The results suggest that metacarpals are structures that can be used for sex determination in paleoanthropological and forensic identifications.
人类学家和法医病理学家通过分析骨骼残骸中的定量和定性特征来确定骨骼的性别。一般来说，头骨和髋骨是最常使用的部位，但它们并不总是保存完好。在这种情况下，研究人员需要掌握基于其他残骸的其他技术。本研究的目的是利用掌骨形态学开发并描述用于确定西班牙现代人群性别的判别函数。对存放在马德里康普顿斯大学（UCM）的一组西班牙现代人群的骨骼样本进行了分析。该样本包括697根掌骨，对应79名成年人（37名男性和42名女性）。由此我们获得了120个单因素判别函数。我们从双手的每根掌骨中各选出10个方程，这些方程提供了最佳的性别判别效果。正确的性别分类准确率从右手（R）第四和第五掌骨的81%，到左手（L）第二掌骨的91%。结果表明，掌骨是可用于古人类学和法医鉴定中性别确定的结构。
