ABSTRACTS OF ORIGINAL ARTICNAL ARTICLES The Early CT Scanning of Discitis after Operation

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．

Discitis is a rare complication of operation on the disc. CT scanning had been made in l4 cases,9 cases in male and 5 cascs in fcmale.There were 9 cases in L4-5 and 5 cases in L5-S1.Symptomsbegan fivc and ten days after operation.CT scan had been made from 3 to 10 days with an averageof 7.1 days.CT scan showed erosion of the end -plates,defects and irregular of intervertebral edge and later intervertebral cavitation.There was air remained in intervertebral space.The soft tissuein both of intervertebral body and nervc root showed the edema、Incidence,pathology and clinicalvalue of CT scan of discitis were discussed.It is recommended that CT seanning is useful in provid.ing early typical radiographic finding of discitis and in guiding clinical treatmoent.
