Sequestration of a disc herniation is an important cause of failure of chemonucleolysis. It therefore is important to recognize this particular variety of disc herniation before considering enzymatic discectomy. In order to determine the clinical and myelographic signs of sequestration, we reviewed the charts, myelograms, and surgical findings of 98 patients operated on for a disc herniation. A correlation was made between the three anatomic types of disc herniation found during surgery and the clinical and myelographic signs observed preoperatively. No characteristic clinical sign was found. No pathognomonic myelographic features were discovered. However, when the myelographic defect appears irregular and at a distance from the disc space, sequestration should be highly suspected.
椎间盘突出的游离是化学髓核溶解术失败的一个重要原因。因此，在考虑酶促椎间盘切除术之前，识别这种特殊类型的椎间盘突出很重要。为了确定游离的临床和脊髓造影征象，我们回顾了98例因椎间盘突出接受手术的患者的病历、脊髓造影片和手术结果。对手术中发现的三种解剖类型的椎间盘突出与术前观察到的临床和脊髓造影征象进行了相关性分析。未发现特征性临床体征。未发现具有诊断意义的脊髓造影特征。然而，当脊髓造影缺损显得不规则且远离椎间盘间隙时，应高度怀疑游离。
