髋骨坐耻臼三角区的测量及其性别判别分析

MEASUREMENT OF THE ISCHIUM-PUBIS-ACETABULUM TRIANGULAR AREA OF THE HIPBONE AND ITS SEX DISCRIMINANT ANALYSIS

目的：积累国人资料，探讨髋骨性别判别分析。方法：对耻弓最小宽、臼耻指数等１０项指标进行测量和计算（在传统方法基础上增加髋臼径、坐骨长ＩＩ及耻骨长ＩＩ）；选取其中 ６项指标用 ＳＰＳＳ软件包进行 Ｆｉｓｈｅｒ法性别判别分析。结果：得出５个单因素及４个多因素判别分析式，其中单因素判别分析的正确判别率为５１．２％～８５．４％，多因素性别判别分析的正确判别率为８４．８％～８７．８％。结论：新测量方法的判别率高于传统方法；髋骨坐耻臼三角区有显著的性别差异，具有实际应用价值。

To accumulate the data of Chinese and to understand the sex discriminant analysis of hipbone. Methods: Ten factors such as the minimum breadth of pubic-arch, acetabulopubic index were used to measure and calculate (all of them are according to the traditional osteometry except of the length of ischium II and the length of pubis II ), six of them were used to calculate 4 discriminant formulae with one to 4 factors. Results: The results showed that correct the ratio was 84. 8%-87. 8% by over 2 factors. Conclusion: The reliable rate of new measurements is higher than that of the old. The ischium-pubis-acetabulum triangular area of the hipbone between male and female is obviously diffent, it's valuable for practice.
