【摘要】 为积累国人椎管解剖学形态资料 ,取成人干燥椎骨 12 5套 ,用游标卡尺等测量了颈、胸、腰椎的椎孔矢径和横径。结果表明椎管矢径颈部C1、C2 为最大 ,C3 ～C7最小 ;胸部大于颈部 ,腰部大于胸部。椎管横径颈部除C1～C2 为最大外 ,C3 ～C7较宽 ,胸部最窄 ,腰部亦较宽。椎管形态C1、C2 为近似圆形 ,C3 ～C7、T1和L5为三角形 ,T2 ～T12 为趋向圆形或近似圆形。表明椎管的形态与对应的脊髓外形在颈部不一致 ,在胸、腰部则基本一致更多还原

【Abstract】 To study the features of anatomic morphology of Chinese vertebral canal, the sagittal diameter and transverse diameter of the vertebral canals of cervical vertebra, thoracic vertebra, lumber vertebra of 125 sets of dried specimens of adult vertebral canals were measured by vernier caliper. The results showed that the sagittal diameter sequence of the vertebral canals from the biggest to the smallest were lumber vertebra, thoracic vertebra, cervical vertebra, and the sagittal diameter of C 1 ～C 2 were bigger than that of C 3 ～C 7; the transverse diameter of thoracic vertebral canals was the smallest, while the transverse diameter of lumber vertebral canal and the vertebral canals of C 3 ～C 7 was bigger, and the transverse diameter of C 1 ～C 2 was the biggest in cervical vertebra; the morphology of C 1 ～C 2 and T 2～T 12 was similar round, while the morphology of C 3 ～C 7, T 1, L 1～L 5 was triangle. Suggesting that the morphology of vertebral canals and of the corresponding spinal cords are not identical in cervical vertebra, while they are identical in lumber and thoracic vertebra by and large.更多还原
