The study was concerned with the human spinal column reaction to axial static and dynamic loading. Fresh segments of the column from dorsal vertebra XI to lumber vertebra II were exposed to axial static (20 mm/min) and dynamic (200 and 500 mm/min) loading. Measured variables included load value, whole segment deformation, anterior surfaces of intervertebral disk Th(XI)-Th(XII) and dorsal vertebra XII, and acoustic emission signals indicative of spongy bone microdestruction. It was found that vertebral body deformation augmented less in comparison with the intervertebral disk and that central parts of the spinal end plates compress greater than peripheral. This difference was more considerable due to static loading rather than dynamic. To produce deformation of a spinal segment by dynamic loading same as by the static one, it is necessary to overcome a stronger resistance of a larger number of trabecular bones. Herefrom it follows that, first, to cause an equal segment compression the dynamic load must be heavier than static and, which is of paramount practical significance, dynamic strength of the column is markedly higher than static. Secondly, spinal stiffness during impact is higher as compared with the static condition. Thirdly, same degree of deformation due to dynamic loading should result in a larger volume of microdestructions comparing with static loading, which is testified by a reliable difference in the number of AE signals accumulated prior to fracture. The number of AE signals amounts to 444.2 ± 308.2 and 85.0 ± 36.6 in case of the dynamic and static loading, respectively (p < 0.05 according to Student's t-criterion).
