The objective of the presented work was to investigate anatomical structures of the cervial spine and their interrelations on cervical myelograms in a neutral position and in retroflexion. Cervical myelograms were made in 34 patients from a lateral approach between the first and second vertebra. In a neutral position and in retroflexion the relations of the dural sac and spinal canal were investigated in 26 subjects with a normal antero-posterior diameter of the spinal canal and in eight patients with congenital stenosis of the spinal canal. Quantification by means of a computer revealed that in retroflexion the antero-posterior diameters of the dural sac diminishes significantly in subjects with a normal antero-posterior diameter of the spinal canal as well as in subjects with congenital stenosis of the spinal canal. Moreover, the authors provided evidence that the area of the dural sac diminishes significantly in retroflexion, as compared with the neutral position in subjects with a normal spinal canal as well as in subjects with congenital stenosis of the spinal canal.
本研究的目的是在中立位和后伸位观察颈椎的解剖结构及其在颈椎脊髓造影中的相互关系。对34例患者经第一和第二椎体之间的外侧入路进行颈椎脊髓造影。在中立位和后伸位，对26例椎管前后径正常的受试者及8例先天性椎管狭窄患者的硬膜囊与椎管的关系进行了研究。通过计算机量化显示，无论是椎管前后径正常的受试者还是先天性椎管狭窄的受试者，在后伸位时硬膜囊的前后径均显著减小。此外，作者还证实，与中立位相比，无论是椎管正常的受试者还是先天性椎管狭窄的受试者，在后伸位时硬膜囊面积均显著减小。
