This paper reports the results of a biomechanical study of 43 human spinal ligaments from fresh cadavers and living subjects. Tensile tests were performed with an original testing machine. The tension load and relaxation were applied at the same constant slow rate (1 mm min-1) on entire ligaments. In order to avoid ligament injuries, fixation in the apparatus was on the bone held in clamps specifically designed for each bone, never the ligament itself or its bony attachments. All the load-deformation curves had a sigmoid shape and during load-unload cycles ligaments exhibited elastic properties. This was particularly evident for the ligamentum flavum. The intertransverse posterior longitudinal ligament and the ligamentum flavum were the most resistant. The elongation-tension curve pattern may be explained by the microscopic architectural change that was studied in supraspinous ligament.
本文报告了对来自新鲜尸体和活体受试者的43条人体脊柱韧带进行生物力学研究的结果。使用一台原创测试机进行拉伸试验。以相同的恒定慢速（1毫米/分钟）对整个韧带施加张力负荷和松弛。为避免韧带损伤，在专门为每块骨头设计的夹具中对骨头进行固定，而非韧带本身或其骨附着点。所有负荷-变形曲线均呈S形，在加载-卸载循环中韧带表现出弹性特性。这在黄韧带中尤为明显。横突间后纵韧带和黄韧带最具抵抗力。伸长-张力曲线模式可通过在棘上韧带中研究的微观结构变化来解释。
