Computed tomography is a very sensitive and fairly specific imaging mode for diagnosing herniated disks in patients with low back pain and radiculopathy. We describe a new CT sign associated with posterior disk herniation that consists of a bony defect on the lower posterior angle of the proximal vertebral body and endplate shown on CT generated digital radiograms. This finding, by no means constant, is encountered frequently enough to be described as a sign of posterior disk protrusion. It often occurs concomitantly with posterior avulsion of a bone fragment probably related to avascular bone necrosis of the posterior inferior angle of the endplate.
计算机断层扫描是诊断下腰痛和神经根病患者椎间盘突出症的一种非常敏感且相当特异的成像方式。我们描述了一种与后位椎间盘突出相关的新的CT征象，该征象表现为在CT生成的数字X线片上显示的近端椎体和终板下后角的骨质缺损。这一发现并非始终存在，但出现频率足以将其描述为后位椎间盘突出的征象。它常与可能与终板后下角缺血性骨坏死相关的骨碎片后位撕脱同时发生。
