The objective of this study was to provide a method of sex determination for Chinese femur, especially for fragmentary remains. Statistical analysis of 17 measurements based on 141 northeastern Chinese femora shows that all measurements have significant sex differences. Sex determination by the midpoint method of a single measurement can obtain an average accuracy of 76.8%. The results indicate that of all dimensions the maximum head diameter is the best discriminator of sex. It alone can determine the sex of a femur with 85.1% accuracy. The results also show that maximum head diameter, transverse head diameter, epicondylar breadth, upper breadth, and medial condylar length have higher sexual dimorphisms than the dimensions of length. According to the result to stepwise discriminant analysis and the need for sexing fragmentary remains, 22 discriminant functions composed of various combinations of variables were calculated which can determine the sex of the femur correctly 82.3 to 87.2%. The methods of sex determination provided by this paper can be used to sex poorly preserved femora.
本研究的目的是提供一种针对中国股骨，尤其是残缺股骨的性别鉴定方法。基于141例中国东北股骨的17项测量数据进行统计分析，结果表明所有测量值均存在显著的性别差异。采用单一测量的中点法进行性别鉴定，平均准确率可达76.8%。结果表明，在所有测量维度中，股骨头最大直径是性别最佳判别指标。仅据此就能以85.1%的准确率判定股骨的性别。结果还显示，股骨头最大直径、股骨头横向直径、髁上宽度、上部宽度和内侧髁长度的两性差异比长度维度更高。根据逐步判别分析结果以及对残缺股骨进行性别鉴定的需求，计算了由不同变量组合构成的22个判别函数，其判定股骨性别的准确率可达82.3%至87.2%。本文提供的性别鉴定方法可用于对保存不佳的股骨进行性别鉴定。
