Observation of thoracic intervertebral foramina ligaments in adults and its significance
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.
