Abstract
The whole straightened ligamentous cervical spinal column (C0/C1-T1) was represented by a three-dimensional segmented beam-column computer model, where vertebral bodies were treated as three-dimensional rigid body elements and intervertebral joints as three-dimensional joint elements having stiffness in axial compression-tension, antero-posterior and lateral shears, and flexural rotations (flexion-extension and lateral bending). Buckling modal analysis of this model estimated the potential responses of the cervical spine subjected to axial head impact. The calculated theoretical buckling loads are in agreement with the peak forces obtained in some of the cadaveric experiments of the cervical spine subjected to axial compressive loading.
