目的　通过解剖观测成人胸椎间孔韧带，为国人提供胸椎间孔韧带的解剖学资料并探讨其临床意义。  方法　选用成人尸体标本15具，解剖观察胸椎间孔韧带，用游标卡尺进行相关测量。　结果　在30侧成人胸椎标本中未发现横孔上韧带和体横韧带，T1椎间孔内未发现横孔下韧带，T2~T12椎间孔内均发现横孔下韧带，其出现率从T2~T12呈逐渐增加的趋势，分别为6.7%、16.7%、30.0%、43.3%、　50.0%、83.3%、82.1%、84.6%、83.3%、87.5%、95.5%。  结论　成人胸椎横孔下韧带在胸椎间孔内普遍存在，当其肥厚、钙化压迫胸神经根时可以将其切断。

Objective　To study the significance of the thoracic intervertebral foramina ligaments in adults.　Methods　The thoracic intervertebral foramina ligaments were dissected and observed in 15 cases of the adult cadavers. The related data were measured with vernir caliper.　Results　No superior transforaminal ligaments and corportransverse ligaments were found in all specimens. No inferior transforaminal ligaments were found in T1. The inferior transforaminal ligaments were found in T2~T12. And their occurrence rates were 6.7%、16.7%、30.0%、43.3%、50.0%、83.3%、82.1%、84.6%、83.3%、87.5%、95.5% respectively in T2 ~T12.  Conclusions　The thoracic intervertebral foramina ligaments are the normal components of the thoracic intervertebral foramen in adults. They may be cut when they press the thoracic nerve roots because of thickening and calcification.
