The organization of collagen in the supraspinous, interspinous, and longitudinal ligaments, as well as the ligamenta flava, in lumbar spines from human cadavers has been investigated by polarized light microscopy, scanning electron microscopy, and x-ray diffraction. These experiments were performed on ligaments in situ, with their bony attachments undisturbed, and on excised ligaments at a range of applied strains. Results were related to the composition (investigated by standard histologic techniques) and gross structures (investigated by light microscopy) of the ligaments. More importantly, the results were related to the mechanical properties of the ligaments, which include stiffness, failure conditions, stress relaxation, and hysteresis. Where necessary, results were supplemented by or compared with those obtained from pig ligaments. Mechanical properties were related to postural changes by ligament strains induced in cadaveric specimens, using results from the literature. Thus, ligament structures could be related to their physiologic functions.
通过偏振光显微镜、扫描电子显微镜和X射线衍射，对取自人类尸体腰椎的棘上韧带、棘间韧带、纵韧带以及黄韧带中的胶原蛋白组织进行了研究。这些实验在韧带原位进行，其骨附着点未受干扰，同时也对在一系列施加应变下的离体韧带进行了实验。结果与韧带的组成（通过标准组织学技术研究）和大体结构（通过光学显微镜研究）相关。更重要的是，结果与韧带的力学性能相关，包括刚度、失效条件、应力松弛和滞后现象。必要时，结果通过取自猪韧带的结果进行补充或比较。利用文献中的结果，通过尸体标本中韧带应变引起的力学性能与姿势变化相关。因此，韧带结构与其生理功能相关。
