【摘要】 目的:为胸椎管狭窄提供解剖学资料。方法:对100套华北地区出土自然干燥胸椎1187个的椎孔进行测量和观察。结果:发现有发育性胸椎管矢径狭窄的13个,占总数的1.1％;椎孔周边有骨质增生及椎板过厚可能造成胸椎管退行性狭窄的有66个,占总数的5.56％。结论:胸椎管狭窄部位多发生于胸椎管的中、下段。更多还原

【Abstract】 Objective: To provide anatomical data for narrow thoracic vertebral conal. Methods: 1187 thoracic vertebrae from 100 skeletons (naturally dried) unearthed in the area of North China were measured and observed. Results: The findings showed that there were 13 cases of growing narrow thoracic vertebrae m sagittal diameter(1. 1 % of 1187); 66 retrograde degeneration narrow thoracic vertebrae caused by substantia losses around vertebral foramen and thickness of Lamina(5.5% of 1187).Conclusion:Most of narrow canals were located in the middle and lower part of the thoracic vertebrae.更多还原
