31 myelograms of patients with the syndrome of lumbar spinal canal constriction were analysed. Two forms can be distinguished - a primary form with hypoplasia of the lumbar section of the spinal canal, and a secondary form with circumscribed constriction through olisthy or spondylosis deformans. The characteristics symptoms of the primary form (n = 21) are: difficult lumbar puncture, the ascent of the contrast medium in the thoracic section of the vertebral canal, multiple protrusions of the intervertebral discs, reduced sagittal diameter of the dural area which is marked by additional signs of spondylosis. In this connection, the alterations were so characteristic that it was possible to diagnose the condition even before the operation. The myelogram with water-soluble contrast-medium is considered to be markedly superior to other methods of radiological examination.
对31例腰椎管狭窄综合征患者的脊髓造影进行了分析。可区分出两种类型——椎管腰段发育不全的原发性类型，以及通过椎体滑脱或脊柱关节病导致局限性狭窄的继发性类型。原发性类型（n = 21）的特征性症状为：腰椎穿刺困难、造影剂在椎管胸段上升、椎间盘多处突出、硬脊膜区域矢状径减小，并伴有脊柱关节病的其他体征。就此而言，这些改变非常典型，甚至在手术前就能诊断病情。水溶性造影剂脊髓造影被认为明显优于其他放射学检查方法。
