Summary
Cadaveric specimens consisting of two lumbar vertebrae and the intervening disc were subjected to cyclic forces in order to study the creep properties of the intervertebral disc. The results show that the upper vertebrae crept forward symmetrically and by amounts dependent on the degree of disc degeneration and the applied force.
Résumé
On a soumis une pièce cadavérique consistant en deux vertèbres lombaires unies par leur disque à des contraintes alternées afin d'apprécier l'élasticité du disque intervertèbral. Cette étude montre que la vertèbre supérieure glisse vers l'avant de façon symétrique, l'importance du déplacement dépendant du degré de dégénérescence discale et de la force appliquée.
