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.展开更多

Although the advent of modern spinal surgery in China was late, we have gained some advanced achievements owing to various international communications benefited from the open policy. Therefore, it is essential to evaluate the current status and perspective of diagnosis and treatment of thoracolumbar fracture. There are several issues we would like to discuss here.展开更多
