国人椎体的测量与分析

目的：提供骨性脊柱的解剖学形态基础。方法：用游标卡尺等，对成都地区１２５套成人干燥椎骨的椎体进行测量。结果：椎体矢径除Ｃ７和Ｌ５外，其他由上而下矢径依次增大；椎体横径大于同一椎体的矢径；椎体高度为Ｃ３～Ｃ６逐渐减小、Ｃ７～Ｌ５依次增大。结论：椎体矢径、横径及高度的变化，符合脊柱运动及依次从上至下负重递增的要求。

Survey and analysis of vertebral body

Objective: To provide a basis of anatomic formation of spinal column. Methods: To survey 125 sets of dried adult vertebra with vernier calliper,etc.WT5HX]Results: With the exception of C7 and L5 of vertebral radius vector,other radius vectors become larger in turn from top to bottom;The transverse diameter is bigger than the radius vector in the same vertebra;Vertebral heights of C3 to C6 gradually become lesser,those of C7 to L5,in turn,get bigger. Conclusion: The change of vertebral radius vector,transverse diameter heights accord with the demands of spinal column movement and weightbearing crescendo.
