Biomechanical Efficacy of Various Anterior Spinal Fixation in Treatment of Thoraco-lumbar Spine Fracture: Ye Soo Park, Hyoung Jin Kim, Choong Hyeok Choi, Won Man Park, Yoon Hyuk Kim; J Korean Fract Soc 2007;20(1):70-75. Published online January 31, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.1.70

PURPOSE
To evaluate the biomechanical results according to various anterior spinal fixation methodology in the treatment of thoracolumbar spine fracture.
MATERIALS AND METHODS
The 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.
RESULTS
In 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.
CONCLUSION
Authors recommend the usage of two-rod system in anterior fixation only and anterior one-rod system in anterior-posterior fixation.

Nonoperative Management of Stable Thoracolumbar Fracture with Bracing in Old Age: Jong Oh Kim; J Korean Soc Fract 1996;9(3):750-758. Published online July 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.3.750

Abstract PDF: Fourteen neurologically intact patients with stable fractures at the thoracolumbar junction above 60yrs old age were treated with early ambulation in a total contact orthosis, Jewett Brace, Knight-Taylor Brace and had followed up greater than one year. Spinal orthosis have been traditionally used in the management of thoracolumbar junction treated with or without surgical stabilization However, the orthotic treatment modality in the management of spinal fractures remain subjective, especially old age. since few objective data are available on the effectiveness of orthosis in stabilizing injuried segments. At minimum follow up of one year, an overall outcome evaluation involved verbal numerical scale ( VNS ) and radilogical assessment. Approxiamately 80% of the patient had under 3 points in the verbal numerical scale, serial roentgenograms documented significant progressing in body collapse which averaged 9.6% compression,5.2 in Cobbs angle, not correlate with type of brace. Mainly body collapse and increasing Cobbs angle at the fracture site developed within posttraumatic 3 months. Degree of osteoporosis did not correlate with change in deformity. Initial radiographic severity of injury or residual deformity following closed management did not correlate with symptoms at follow-up. This pattern of results suggested comportable brace treatment such as Jewett and Knight-Taylor Brace, as the preferred treatment in stable thoracolumbar fracture in old age.
