The diagnosis of herniated intervertebral disc is often made in cases of radicular pain in the low back, the neck, or sciatica or brachialgia. Practitioners often call upon radiologic imaging to confirm this diagnosis. But on radiologic examination, such a herniation may consist of a bulge, protrusion, prolapse, extension, extrusion or sequestration of this disc. We define and illustrate these terms from the literature. We then review the radiologic studies of normal controls, who have never had sciatica, brachialgia or pain in the low back or neck. In over one-quarter of these controls, studies using the plain x-ray, CT scan, myelogram, and MRI show various radiologic signs of a herniated intervertebral disc. We therefore recommend that practitioners should not exclusively rely on radiologic imaging to confirm the clinical diagnosis of a herniated intervertebral disc.
腰椎间盘突出症的诊断通常基于下背部、颈部的神经根性疼痛，或坐骨神经痛或臂丛神经痛的病例。从业者常常借助放射影像学检查来确诊。但在放射学检查中，这种椎间盘突出可能表现为椎间盘的膨出、突出、脱垂、延伸、挤出或游离。我们从文献中定义并阐释了这些术语。接着，我们回顾了从未患过坐骨神经痛、臂丛神经痛或下背部或颈部疼痛的正常对照者的放射学研究。在超过四分之一的这些对照者中，使用普通X线、CT扫描、脊髓造影和MRI的研究显示出椎间盘突出的各种放射学征象。因此，我们建议从业者不应仅仅依靠放射影像学来确诊腰椎间盘突出症的临床诊断。
