Mechanism of thoracolumbar burst fractures: a biomechanical study / 中华医学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the mechanism associated with thoracolumbar burst fractures.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>Stress concentration was noted at the pedicle and posterosuperior part of the vertebral body near the pedicle.</p><p><b>CONCLUSION</b>Stress concentration of the spine may be implicated in the biomechanical mechanism underlying thoracolumbar burst fractures.</p>
