Zusammenfassung
Messungen an Ausgußpräparaten von Duralsäcken ergaben Kenndaten zur Charakterisierung der “inneren Silhouette” des lumbalen Spinalkanals. Statistisch gesichert stellten sich drei Gruppen mit unterschiedlichen Formeigenschaften des Duralsackes dar. Diese sind konstitutionell determiniert. Die differente Raumkapazität der drei Typen und die unterschiedliche Relation der Durchmesser relativieren den Wert der isolierten ermittelten Distanz, beispielsweise des sagittalen Durchmessers bei L 5, was klinisch von erheblicher Relevanz ist.
Abstract
Measurements of cast preparations of epidural cavities yielded data characterising the “internal silhouette” of the lumbar vertebral canal. Three groups of different shapes of lumbar vertebral canal were found to be statistically distinguishable from each other. These are determined by the constitution of the patient. The different spatial capacity of the three types and the different relations of the diameters modify the value of the isolated determined distance, for example of the sagittal diameter at L 5, which is a clinically extremely relevant factor that must be taken into account.
