The concept of the three-column cervical spine and load transmission through each column was experimentally tested. Material consisted of five cervical columns removed from cadavers. The experiment was conducted on an Instron load testing machine. Load was applied on superior articular surfaces of the axis vertebra and was recorded below from each column separately at the level of the sixth cervical vertebra. It was found that 36% of the total load applied on the top of the specimen is transmitted through the anterior column formed by bodies and intervertebral discs and 32% each through the two posterior cervical columns formed by the articular processes. The experiment very strongly supported the role of neural arch in transmission of vertebral compressive forces.
对颈椎三柱的概念以及通过每柱的负荷传递进行了实验测试。材料包括从尸体上取下的五个颈椎柱。实验在英斯特朗材料试验机上进行。负荷施加在枢椎的上关节面上，并在第六颈椎水平分别从每个柱的下方记录。结果发现，施加在标本顶部的总负荷的36%通过由椎体和椎间盘形成的前柱传递，32%分别通过由关节突形成的两个颈椎后柱传递。该实验有力地支持了神经弓在椎体压缩力传递中的作用。
