我们对67名从未有过腰痛、坐骨神经痛或神经源性跛行的患者进行了磁共振成像。扫描结果由三名神经放射科医生独立解释，他们对受试者是否存在临床症状一无所知。约三分之一的受试者被发现有实质性异常。在那些不到60岁的人中，20%的人患有髓核突出症，一人患有椎管狭窄症。在60岁或60岁以上的一组中，大约57%的扫描结果是异常的：36%的受试者有髓核突出，21%有椎管狭窄。在20 ~ 39岁的受试者中，35%的受试者至少有一个腰椎节段存在椎间盘退变或膨出，而在60 ~ 80岁的受试者中，除1人外，其余均存在椎间盘退变或膨出。鉴于无症状受试者的这些发现，我们得出结论，在考虑手术治疗之前，磁共振图像上的异常必须与年龄和任何临床体征和症状严格相关。
We performed magnetic resonance imaging on sixty-seven individuals who had never had low-back pain, sciatica, or neurogenic claudication. The scans were interpreted independently by three neuroradiologists who had no knowledge about the presence or absence of clinical symptoms in the subjects. About one-third of the subjects were found to have substantial abnormality. Of those who were less than sixty years old, 20 per cent had a herniated nucleus pulposus and one had spinal stenosis. In the group that was sixty years old or older, the findings were abnormal on about 57 per cent of the scans: 36 per cent of the subjects had a herniated nucleus pulposus and 21 per cent had spinal stenosis. There was degeneration or bulging of a disc at at least one lumbar level in 35 per cent of the subjects between twenty and thirty-nine years old and in all but one of the sixty to eighty-year-old subjects. In view of these findings in asymptomatic subjects, we concluded that abnormalities on magnetic resonance images must be strictly correlated with age and any clinical signs and symptoms before operative treatment is contemplated.
