OBJECTIVE To investigate the mechanism associated with thoracolumbar burst fractures. METHODS Stress distribution of the spine in the upright, flexion and extension positions was analyzed using a three-dimensional finite element model of the spinal motion segment. RESULTS Stress concentration was noted at the pedicle and posterosuperior part of the vertebral body near the pedicle. CONCLUSIONS Stress concentration of the spine may be implicated in the biomechanical mechanism underlying thoracolumbar burst fractures.

D021621	Imaging, Three-Dimensional	The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.
