We carried out experiments on whole cadaveric lumbar spines in order to determine the role that each of the capsulo-ligamentous structures play in axial rotation in the neutral position and in the flexed position. Eight specimens were first tested intact, then after division of all the apophyseal joint capsules between L1 and the sacrum. Another five specimens were also first tested intact, then after division of the supra- and interspinous ligaments and yellow ligament, and finally after cutting the posterior longitudinal ligament and posterior annulus at each level as well. The results show that there is considerable variation in the axial rotation of the lumbar vertebrae within the same spine and across different spines. The apophyseal joint capsules limit rotation both in neutral and flexed positions. In flexion, the amplitude of rotation in the lumbar spine is reduced. Of the capsulo-ligamentous structures, it is the posterior annulus and the posterior longitudinal ligament that seem to play the more important role in limiting axial rotation while the spine is flexed.
我们对完整的尸体腰椎进行了实验，以确定每个关节囊韧带结构在中立位和屈曲位时对轴向旋转所起的作用。首先对8个标本进行完整测试，然后切断L1与骶骨之间所有的椎间关节囊。另外5个标本同样先进行完整测试，然后切断棘上韧带、棘间韧带和黄韧带，最后在每个节段切断后纵韧带和后纤维环。结果表明，同一脊柱内以及不同脊柱之间，腰椎的轴向旋转存在相当大的差异。椎间关节囊在中立位和屈曲位时均限制旋转。在屈曲时，腰椎的旋转幅度减小。在关节囊韧带结构中，后纤维环和后纵韧带在脊柱屈曲时似乎在限制轴向旋转方面发挥着更重要的作用。
