To help understand spinal injuries occurring in aircraft pilots exposed to vertical-impact acceleration forces, the effects of rate and percentage of vertebral body deformation on microfracture distribution in the lumbar vertebrae of the rhesus monkey were evaluated. Vertebral body compression tests indicated that 25% deformation marks the initial point where central zone fractures consistently occur. In addition, subfailure loading of the vertebral bodies produced injuries to the regions that contain the major vascular and possibly neural components of the vertebral centrum.
