Abstract

A multi-thin slice quantitative computed tomography technique was used to determine the three-dimensional density distribution of the trabecular bone from a group of vertebral bodies in vitro. The average bone density in six cylindrical regions, in each of three axial layers was measured, for a total of 18 cylindrical regions of cancellous bone between the endplates. Both static and fatigue uniaxial compression tests were conducted on the vertebral bodies to determine whole bone failure properties. Relationships were developed between regional densities of the vertebral cancellous bone and vertebral failure properties. Strong correlations were generated between combinations of regional densities and static failure properties (r2 = 0.89), and fatigue failure properties (r2 = 0.98).
