摘要
腰椎韧带具有重要的生物力学功能。采用三维有限元方法进行的研究表明,腰椎韧带的作用之一是在腰椎间传递拉伸载荷,腰椎后伸时主要由前纵韧带受载,其余韧带则在腰椎前屈时发挥作用。当椎间盘发生退变后韧带所受拉力增大,可能会引起一系列病理变化。作者就其临床意义进行了讨论。
The lumber ligaments play an important role in spinal bsomechanics. The results of three-dimensional finite element analysis showed that one of functions of lumbar ligaments is transmission of the tensile load between the lumbar vertebrae. The anterior longitudinal ligament is loaded in extension of lumbar spine and the resistance to the tensile load in flexion is provided by other ligaments. These ligaments are subject to much more tension with degsneration of the intervertebral disc so that a series of pathological changes occur. Relevant significance in clinical aspect is also discussed.
