The role of the narrow lumbar spinal canal in back and sciatic pain is well established. The accuracy of measurements obtained from lumbar radiographs was therefore analyzed in lumbar spine specimens taken from 132 male cadavers. After removal of soft tissues, the same distances were measured on the bones of 80 specimens. Comparisons were made after correction for magnification, the radiographic measurements of interpedicular distances being, on average, 2 mm greater at L3 than the osteologic ones and 4 mm greater at L5. Interarticular distances, midsagittal diameters, and pedicular lengths were, on average, 1 mm greater and foraminal anteroposterior measurements 1 mm less than the osteologic ones. Body stature correlated with interpedicular and interarticular distances, pedicular length, and foraminal anteroposterior measurements. In older age groups, the midsagittal diameter tended to be reduced. A number of correlations were found between the five measurements, e.g. between the anteroposterior diameter of the intervertebral foramen and the pedicular length. Measurements in the transverse plane were independent of those in the anteroposterior plane. These results confirm and amplify preliminary observations and indicate the potential value of simple measurements on lumbar spine films as an alternative to more sophisticated and expensive radiologic investigations.
腰椎管狭窄在腰背痛和坐骨神经痛中的作用已得到充分证实。因此，对取自132具男性尸体的腰椎标本的腰椎X线片测量准确性进行了分析。去除软组织后，对80具标本的骨骼进行了相同距离的测量。校正放大率后进行比较，L3椎弓根间距的X线测量值平均比骨测量值大2mm，L5大4mm。关节间距离、矢状径和椎弓根长度平均比骨测量值大1mm，椎间孔前后径测量值比骨测量值小1mm。身高与椎弓根间距、关节间距离、椎弓根长度和椎间孔前后径测量值相关。在老年组中，矢状径有减小的趋势。在这五项测量值之间发现了一些相关性，例如椎间孔前后径与椎弓根长度之间的相关性。横断面测量与前后平面测量无关。这些结果证实并扩展了初步观察结果，并表明腰椎X线片上简单测量作为更复杂、昂贵的放射学检查的替代方法的潜在价值。
