椎间盘髓核摘除术后并发椎间盘炎．临床比较少见．但是一个严重的并发症。本组１４例，男９例，女５例。腰４，５椎间盘炎９例，腰５～骶１椎间盘炎５例．术后５～１０天出现症状．平均７．６天．术后３一１０天行ＣＴ检查．平均７．１天ＣＴ显示椎体软骨板破坏，有缺损，椎体边缘呈毛刷状．参差不齐．椎体后缘有空洞形成．椎间隙内有残留气体．椎旁软组织肿胀。ＣＴ显示椎管内神经根稍有水肿．硬膜囊无受压现象．文章讨论了术椎间盘炎的发病率和病因及ＣＴ在椎间盘炎诊断中的价值，ＣＴ能为临床早期判断术后有无椎间盘炎提供可靠的影像学证据．指导临床选用适当的处理方法．
Intervertebral discitis after discectomy of disc. Clinical relatively rare. But a serious complication. The group of 14 cases, 9 males and 5 females. 4, 4 discitis in 9 cases, lumbar 5 ~ sacral 1 discitis in 5 cases. 5 to 10 days after the onset of symptoms. Average 7.6 days. Postoperative 3 to 10 days CT examination. An average of 7.1 days CT showed vertebral cartilage destruction, defect, vertebral edge was brush-like. Spotty. There are holes in the posterior edge of the vertebral body. There are residual gas in the intervertebral space. Paravertebral soft tissue swelling. CT showed a slight edema of the nerve root in the spinal canal. Dural capsule without compression phenomenon. This article discusses the incidence and etiology of operative discitis and the value of CT in the diagnosis of discitis. CT can provide reliable imaging evidence for early diagnosis of discitis after operation. Guidance for clinical use of appropriate treatment.
