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.

OBJECTIVE: Recently, the definition of occult osteoporotic vertebral fracture has been established, and its clinical significance has come to our interest. We report the effect of early percutaneous vertebroplasty in occult osteoporotic vertebral fracture. METHODS: From January 2006 to January 2008, we performed percutaneous vertebroplasty for 50 levels in 47 patients. 21 levels (21 patients) of them were classified into occult osteoporotic vertebral fracture group, 29 levels (26 patients) were categorized into control group (not occult osteoporotic vertebral fracture) by the Pham T..s criteria. We obtained VAS score and measured the compression ratio at first hospital day and 1 day, 1 month, 3 months after procedure. RESULTS: There are noticeable improvements in VAS score. The mean VAS score at admission was 6.44 in occult group and 6.15 in control group, which changed 2.23 in occult group and 2.68 in control group after procedure. The compression rate was 1.008, 1.018, 1.016 in occult group and 0.862, 0.891, 0.881 in control group at admission and 1 month, 3 months after procedure. The conservative effect for vertebral height was higher than control group (p=0.011). CONCLUSION: Percutaneous vertebroplasty in occult osteoporotic compression fracture provided significant pain relief and conservative effect for vertebral height. It is probable that it can lower the rate of secondary adjacent vertebral compression fracture.

PURPOSE: To analyze the effect of adjacent vertebral body on local sagittal segment in performing vertebroplasty for thoracolumabr vertebral compression fracture on the terms of radiological results. MATERIALS AND METHODS: We experienced 61 cases of T12 and L1 Compression fracture between June 2003 and November 2005. We classified with 3 groups; no collapse of adjacent body, collapse of adjacent upper body, and collapse of adjacent lower body. The measuring factors were anterior, middle, posterior vertebral height, wedge angle and local kyphotic angle. RESULTS: In group I, Increase rate of anterior, middle, posterior vertebral height and restoration rate of wedge angle, and local kyphotic angle were average of 0.41%, 0.31%, 0.16%, 1.47%, ?3.48% respectively. Group II was -3.19%, 0.11%, -3.02%, -1.23%, -4.63%. Group III was -2.28%, 4.72%, -1.01%, -2.41%, -13.12%. There are no significant differences among the groups except local kyphotic angle in Group III statistically. CONCLUSION: The previous wedged collapse of adjacent vertebral body do not affect local sagittal segment performed vertebroplasty in the thoracolumbar compression fracture. However the previous wedged collapse of adjacent lower body affect significantly local kyphotic angle.
