Nine anatomical parameters that may have a relation to the spinal canal size were directly measured in each of 594 cervical and lumbar vertebrae from young adult cadaver skeletons. The anteroposterior diameter of the spinal canal was the only parameter which could be statistically correlated with its cross-sectional area (P<0.05), and hence justifies the accepted practice of its use as an indicator of bony spinal canal size.

Le diamètre sagittal du canal vertébral est-il un reflet de sa taille réelle? Etudes anatomiques


Neuf paramètres intéressant la taille du canal vertébral ont été mesurés directement sur 594 vertèbres cervicales et lombaires provenant de squelettes d'adultes jeunes. Le diamètre sagittal du canal vertébral s'est révélé être le seul paramètre pouvant être statistiquement corrélé avec la surface de sa section transversale (P<0.05). Ce résultat justifie l'utilisation généralement admise de ce paramètre comme indicateur de la taille du canal vertébral.
