Ligaments of the lower cervical spine (C3 to C7) were studied in 27 canine cadavers. The gross anatomy and attachment sites were determined by dissection, and representative samples of the flaval ligament, facet capsules, and dorsal longitudinal ligament were examined by light microscopy and were stained for elastin content. Selected functional spinal units were placed in a specially constructed humidification chamber and were fixed in position, using methyl methacrylate bone cement. The specimens were stressed in flexion and extension, and vertebral displacement was measured before and after severance of the spinal ligaments. The flaval ligament had a marked elastin content and contained randomly oriented collagen bundles. The dorsal longitudinal ligament possessed a negligible elastic fiber content and demonstrated longitudinally oriented collagen bundles. The facet capsules possessed an inner synovial lining and outer fibrous layer typical of synovial joint capsules. In general, the severance of spinal ligaments resulted in small increments of displacement until failure occurred, which was often sudden and complete. The flaval ligament, facet capsules, dorsal longitudinal ligament, and intervertebral disk were the major ligamentous stabilizers of the lower cervical spine.
对27具犬类尸体的下颈椎（C3至C7）韧带进行了研究。通过解剖确定大体解剖结构和附着部位，对黄韧带、关节囊和后纵韧带的代表性样本进行光学显微镜检查，并对弹性蛋白含量进行染色。将选定的功能脊柱单元置于特制的加湿室中，使用甲基丙烯酸甲酯骨水泥固定在适当位置。对标本进行屈伸应力测试，并在切断脊柱韧带前后测量椎体位移。黄韧带弹性蛋白含量显著，含有随机排列的胶原束。后纵韧带弹性纤维含量可忽略不计，表现为纵向排列的胶原束。关节囊具有滑膜关节囊典型的内层滑膜衬里和外层纤维层。一般来说，脊柱韧带切断会导致位移有小幅度增加，直至发生失效，失效通常突然且彻底。黄韧带、关节囊、后纵韧带和椎间盘是下颈椎主要的韧带稳定结构。
