The computed tomography (CT)/discograms and discographic pain provocation reports of 291 clinical patients, 790 discs (mean age, 38; range, 17-79) were collected. The CT/discograms were classified separating anular disruption and degeneration and recording the pain provoked during discography as no pain, dissimilar, similar, or exact reproduction of the patient's clinical pain. Nondegenerated discs usually were found to be painless, and deteriorated discs painful. The proportion of severely degenerated but painless discs increased with age, as did the discs producing dissimilar pain. This may help explain the poor correlation of low-back pain with radiographic degenerative changes reported in previous epidemiologic studies.
收集了291例临床患者790个椎间盘（平均年龄38岁；范围17 - 79岁）的计算机断层扫描（CT）/椎间盘造影及椎间盘造影疼痛激发报告。CT/椎间盘造影根据纤维环破裂和退变进行分类，并记录椎间盘造影期间诱发的疼痛，分为无疼痛、不同、相似或确切再现患者临床疼痛。通常发现未退变的椎间盘无痛，而退变的椎间盘疼痛。严重退变但无痛的椎间盘比例随年龄增加，产生不同疼痛的椎间盘也是如此。这可能有助于解释先前流行病学研究中报道的腰痛与影像学退变改变之间的相关性较差的原因。
