Abstract
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.
Conclusion:
Stress concentration of the spine may be implicated in the biomechanical mechanism underlying thoracolumbar burst fractures.
