摘要
对183例成人骶骨(男111,女72)进行了研究,试图找出骶骨性别差异,结果发现:骶骨上面,伴>翼的一组有极为显著的统计学意义(P<0.001)。体<翼的一组由于全部为女性骶骨,因此男女之间的性别差异更为显著。骶骨按其长宽比例被划分为三种类型——长骶型、中骶型和宽骶型。其中长骶型和宽骶型性别差异极为显著(P<0.001);中骶型未发现明显的性别差异(P>0.05)。男女耳状面的长度,也显示了一定程度的性别差异,通常女性耳状面的长度短于男性。对骶骨弯曲度也进行了研究,但没有发现明显的性别差异。
Adult sacra(111 from males and 72 from females)were investigated with an attempt to find out the sex-difference.A significant difference of the sacrum upper surface betweem male and female was found in both groups in which the body greater or smaller than the ala.According to the relation of the sacrum length to its width,the sacra were divided into three types,the dolichohieric,subplatyhieric and platyhieric types.There is a significant sex-difference(p<0.001)between the dolichohieric and the platyhieric types.The subplatyhieric type did not show any significant change (p>0.05).There is also a certain signifi ant sex-difference between the lengths of the auricular surface from both sexes.ln the general,length of the auricular surface in the female is shorter than that in the male.The curve of the sacrum was also studied,but no significant sex-difference was found.
