1·OBJECTIVE: to clarify the intervertebral route and its adjacent relationship of lumbar nerve root on thin section and ct section to provide a anatomic gist for puncture route in PLDD.
目的：阐明腰神经根在薄层断面和CT断面上椎间行程及周围结构的毗邻关系，为经皮激光椎间盘减压术的穿刺路径提供解剖学依据。
2·Objective To investigate the diagnostic value of lumbar discography in discogenic low back pain and the effects of intervertebral fusion surgery.
目的应用椎间盘造影对椎间盘源性腰痛进行诊断并评价椎间融合手术的疗效。
3·Conclusion MRI can show the nerve rootlets within the intervertebral foramen, thus, can make a correct qualitative and level diagnosis in brachial plexus pre-ganglionic injuries.
结论：核磁检查可以显示椎间孔周围臂丛神经根的情况，对臂丛神经节前损伤的定性定位可作出较准确的判断。
4·Conclusion ct Myelography can show the nerve rootlets within the intervertebral foramen, thus, help make a correct qualitative and level diagnosis in brachial plexus pre-ganglionic injuries.
结论脊髓造影CT可以显示椎间孔周围神经根的情况，对臂丛神经节前损伤的定性定位可做出准确判断。
5·Objective To study the anatomical factors causing spinal nerves stuck in the cervical intervertebral foramen and the spinal nervous sulcus.
目的探讨颈神经在椎间孔及脊神经沟处受嵌压的解剖学因素。
