A study was made of the association between disc degeneration observed in plain radiographs, in discograms (Adams' classification), and instability expressed as abnormal angular movement of lumbar vertebrae. The series included 169 discs in 77 consecutive patients (42 men, 35 women) whose mean age was 34 (range 16-46) years. Discography was more sensitive than plain radiography in the diagnosis of disc degeneration was more common in men than in women (Chi square test, chi 2 = 9.88, p less than 0.05). An increase in disc degeneration was observed in lower lumbar segments (Chi square test, chi 2 = 48.63 p less than 0.001). However, no association between abnormal angular movement and discogram type was observed (Chi square test, chi 2 = 2.63, p less than 0.05). It seems that disc degeneration seldom results in abnormal angular movement and instability of the lumbar spine. Therefore, flexion-extension radiography may only have limited diagnostic value.
对在X线平片、椎间盘造影（亚当斯分类法）中观察到的椎间盘退变与以腰椎异常角运动表示的不稳定之间的关联进行了研究。该系列包括77例连续患者（42例男性，35例女性）的169个椎间盘，这些患者的平均年龄为34岁（范围16 - 46岁）。在诊断椎间盘退变方面，椎间盘造影比X线平片更敏感，男性比女性更常见（卡方检验，χ2 = 9.88，p < 0.05）。在下腰椎节段观察到椎间盘退变增加（卡方检验，χ2 = 48.63，p < 0.001）。然而，未观察到异常角运动与椎间盘造影类型之间的关联（卡方检验，χ2 = 2.63，p < 0.05）。似乎椎间盘退变很少导致腰椎的异常角运动和不稳定。因此，屈伸位X线摄影可能仅具有有限的诊断价值。
