Thoracolumbar cadaver spine segments were studied by biplane radiography techniques during intradiscal injection of radiographic contrast agent. In these radiographically nondegenerated discs, significant deformation of the end plate accompanied these in vitro discograms. End plate deflections averaged 0.3 mm. The intervertebral disc bulges averaged 0.5 mm. These results suggest that the end plate itself, or events within the bone, are possible pain sources during clinical discography.
在向椎间盘内注射放射造影剂的过程中，采用双平面放射摄影技术对胸腰段尸体脊柱节段进行了研究。在这些放射学上未退变的椎间盘中，这些体外椎间盘造影伴随着终板的显著变形。终板平均偏移0.3毫米。椎间盘平均膨出0.5毫米。这些结果表明，终板本身或骨内的情况可能是临床椎间盘造影期间的疼痛来源。
