- 摘要：Purpose
To evaluate the biomechanical results according to various anterior spinal fixation methodology in the treatment of thoracolumbar spine fracture.
Materials and MethodsThe comparative analysis of fixation method was evaluated by three dimensional finite element model using the 1 mm reconstruction image of CT. Authors evaluated the flexion, extension, lateral bending, torsional stresses with 12 fixation methods for the compression and burst fracture.
ResultsIn biomechanical analysis, stiffness of body-fixation device was more stable in two-rod system in compression fracture and was stable in one-rod, two-rod system in burst fracture, but two-rod system was showed over-increase of stiffness.
ConclusionAuthors recommend the usage of two-rod system in anterior fixation only and anterior one-rod system in anterior-posterior fixation.
