A two-phase experiment was conducted on isolated normal vertebral bodies excised from the Rhesus Macaque at necropsy. The purpose of this experiment was to evaluate the effects of displacement rate and vertebral body position on mechanical properties. The first phase of the experimental tests was performed as a factorial experiment in which 12 vertebrae from each of four monkeys were loaded and mechanically strained at each of three displacement rates. The objective of this phase was to determine the effect of these factors on seven mechanical properties and to determine the appropriate regression model for describing vertebral body response. In the second phase an additional 48 vertebrae were tested at three different intermediate displacement rates other than those of Phase I, again for the various vertebral body positions and according to a factorial arrangement of treatment combination. The results from Phase II were compared to Phase I. The data from the two phases were combined and the parameters of the regression model were estimated for each of the mechanical properties. Author
