摘要/Abstract

摘要： 本文对85例(男46,女39)国人寰椎进行了四项测量,其性差均非常显著,但两性重迭率≥38.9％。另算出两项指数,其性差不显著。从中挑选全宽(X1)和矢径(X2)两个变量经计算得判别式Z=X1+2.21098X2,临界值Z0=172.9102。经组内外回代误判率分别为18.5％和12.9％。对四项测量作了相关分析,其中寰椎矢径与椎孔横径、全宽与椎孔矢径均呈中度正相关。并用寰椎矢径(X2)推算椎孔横径(Y),其男性Y=18.01±0.2579X2,女性Y=4.88±0.5505X2。

Abstract: The measurements on 85 Chinese atlases (46 male and 39 female) have been taken. The main results are as follows.
1. The total transverse diameter (X1) and the antero-posterior diameter (X2 ) of the atlas are 45. 98±0. 46 mm and 78. 36±0. 57 mm in male, 42. 06±0. 37 mm and 70. 9土0. 54 mm in female, respectively.
2. The maximum transverse diameter of the vertebral foramen and the anteroposterior diameter of the vertebral foramen are 29. 76±0. 27 mm and 27. 75±0. 29 mm in male, 27. 75±0. 26 mm and 25. 90±0. 29 mm in female, respectively.
3. The sexual discriminant function is Z=X1+2. 21098 X2, (X1=breadth, X2 = sagittal diameter) and its critical value is Zo=172. 9102. 12. 9-18. 5% of all cases are the miselassified.
