股骨髁X线测量及性别判别分析

THE ROENTGENOMETRY AND SEX DISCRIMINANT ANALYSIS OF FEMORAL CONDYLE

目的：为积累资料和探讨国人股骨髁的性别差异。方法；随机对３３～７６岁１９４例健康人（男１３８，女５６）拍摄膝部正侧位Ｘ线片；在正位片上测量了上髁宽和内、外侧髁宽，在侧位片上测量了内、外侧髁长和高。用ＳＰＳＳ软件计算出 ５个指数和 ７个性别判别分析式。结果：所测７项均具有非常显著的性别差异（ｔ＝３．５３～１３· ９４，Ｐ＜０．０１），５项指数除髁高指数外，均无显著性性别差异；７个性别判别式的国代判别率在７５．４５％～８９．７３％间。结论：股骨髁的Ｘ线测量对性别判别具有一定的实用意义。

To study the difference of femoral condyle between two sexs and accumulate Chinese femoral condyle data. Methods: A hundred and unity four healthy persons (M138,F56), aged 33 to 76, were randomly taken the X-ray films on knees, the bilateral were 69. The epicondylar breadth and the breadth of medial and lateral condyles were measured on the anteroposterior X-ray films, the length and height of medial and lateral condyles on the lateral films were also measured. Five indices and some discriminant formulae were abtained by SPSS software. Results: All the measurements have a very significant sex difference, but the indices had not difference except the height index. The retrospective correct sexual rate of the discriminant formulae were 75. 45% to 89. 73%. Conclusion: It is useful to diagnose the sex for criminal cases with remnant thigh by roentgenometry.
