RESUMO

<p><b>OBJECTIVE</b>To evaluate the biomechanical and clinical effect of the treatment of thoracolumbar fracture with monosegmental pedicle instrumentation in the fracture vertebrae by endplate method.</p><p><b>METHODS</b>Twenty-four porcine thoracolumbal spinal model, divided into four groups randomly, compared the stability of these four groups through pull-out testing. Retrospective study of 49 patients with thoracolumbar fracture who were treated with this technique, to observe the fusion of bone graft, the height of the anterior and posterior range, the angle of kyphosis and the volume of spinal canal, the loss of rectification, low back pain, and the limitation of activity of lumbar.</p><p><b>RESULTS</b>The endplate method group is more stability than the parallel method group, and the pedicle screw in the fracture vertebrae can get enough stability. After operation all 49 cases achieved satisfactory reduction, strong bone fusion, no reduction loss, no refractoriness low back pain, limitation of motion of lumbar et al.</p><p><b>CONCLUSION</b>Monosegmental pedicle instrumentation by endplate method in the fracture vertebrae for thoracolumbar fracture can get enough extraction stability, and get satisfied clinical effect.</p>
