摘要
在56套(男30,女26)青岛和长春地区出土的成人腰骶椎骨骼上观测了腰骶椎上关节突关节面的形态和曲率。关节面的形态可分为隧道型、椭圆型和不规则型。根据其曲率不同可分为圆弧型、平面型和混合型。自上而下,隧道-圆弧型关节面依次增多,关节面的曲率半径逐渐增大,从而使腰骶部脊柱的运动范围自上而下也依次增大。
The shape and curvature of the articular surface of the superior articular process of the lumbosacral vertebrae were observed and measured on 56(30 males, 26 females) adult lumbosacral skeletons unearthed from Qingdao and Changchun districts. The shape of the articular surface could be divided into tunnel-type, ellipse-type and irregular-type. They might be also divided into curve-type, plane-type and mixed-type according to their curvature. The number of tunnel-curve-type and the curvature radius of the articular surface increase gradually from upper to lower level, so that the moving range of the lumbosacral spine increases successively from above downward.
