国人颈椎横突孔的形态观察与测量

本文作者用精密度为0.02毫米的游标卡尺对东北地区出土的100副成套颈椎,1200个颈椎横突孔的诸径进行了测量,得到了一系列数据,并对颈椎横突孔的形状(将它分为五型)及一些特异颈椎进行了观察,根据这些材料探讨了横突孔与椎动脉的关系。

MEASUREMENTS AND MORPHOLOGY OF TRANSVERSE FORAMEN OF CERVICAL VERTEBRA IN CHINESE

The author studied 600 cases of cervical vertebrae including 1200 foramen transversarium, which are from Northeastern China. The shapes of foramen are as follows: a-round; b-oval; c-triangle; d-square;e-double foramina (8-shaped); f-triple foramina.This article describes gome typical morphological characteristics of vertebrae cervicales in detail. For example, there is a laminal ossium on each sulcus arteri aevertebralis of the first vertebrae cervicales, which forms a canal (this has been reported before). The directions of the foramen transversarium of the vertebrae cervicales of the first through sixth are different. Some transverse foramina on both sides are different in size. In the first, through sixth vertebra cervicales there are not any foramen transversarium on one of the two sides of some vertebrae. Some transverse foramina on the right or left side are very small (the average of their aperture is 2.8 mm in diameter). Some transverse foramina on the left side is not of the same size as that on the right. Some transverse foramina are divided into two parts, the compact bone of artieularis processus superior of some vertebrae are overgrown forward, covering the foramen transversarium from the. top, or even covering about four fifth of them.
