CERVICAL SPINE BUCKLING: THE EFFECTS OF VERTEBRAL MASS AND LOADING RATE
The importance of buckling during compressive loading of the cervical spine was suggested by Torg (1985) and has been subsequently demonstrated both quasi-statically2 and dynamically3. The complex deformations resulting from first and second order cervical spine buckling may explain the difficulty in producing repeatable injuries in impact experiments4,5,6. The purpose of this computational study is to test the hypothesis that during compressive impact loading of the cervical spine, the inertial properties of the vertebral bodies play a significant role in determining the buckling behavior. Further, it is hypothesized that these inertial effects provide the necessary constraints for the expression of higher order buckling modes7.
