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.

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.

Postural reduction was performed in 20 cases of the closed thoracolumbar compression fracture using a soft pillow from January 1982 to June 1985. The results were summarized as following: 1) The compression fracture or mild burst fracture of the thoracolumbar spines can be restored by the postural reduction in hyperextension position using a soft pillow under the back of thoracolumbar junction. 2) The postural reduction resulted in not only expansion of a compressed vertebral body but also successful fusion. 3) It was most satisfactory when the postural reduction was performed as early as possible, at least within 1 week after injury. 4) The postural reduction is considered a simple and convenient treatment of the thoracolumbar compression fracture.

PURPOSE: To differentiate malignant vertebral compression fractures from benign fractures, as seen onspin-echo T1-weighted, fast spin-echo T2-weighted, and fat-suppressed gadolinium-enhanced T1-weighted MR images. MATERIALS AND METHODS: Thirty two benign (18 acute and 14 chronic) and 28 malignant vertebral collapses werestudied in 54 patients aged between 15 and 78 (mean, 51) years. Malignant compression fractures involved onlymetastasis. We obtained sagittal and axial fast spin-echo T2-weighted images, and unenhanced and fat-suppressedgadolinium-enhanced T1-weighted images, and analyzed MR signal intensity, enhancement patterns, and morphologicchanges including convex posterior cortex vs retropulsion of a bone fragment, focal vs diffuse paraspinal mass,and epidural mass. RESULTS: All cases of acute benign and malignant compression fractures showed low signalintensity within the vertebral body on T1-weighted images, and substantial contrast enhancement on fat-suppressedgadolinium-enhanced T1-weighted images. Acute benign and malignant compression fractures were distinguished on thebasis of three signal intensity characteristics: hypointense band (acute benign cases 77% ; malignant cases 0%),diffuse low signal intensity(17% vs 86%) and involvement of pedicle (0% vs 75%). Fast spin-echo T2-weighted imagesplayed little role in distinguishing between the two. Three morphologic changes were suggestive of malignancy:convex posterior cortex (malignant cases 75% ; benign 0%), epidural mass (79% vs 5%), and focal paraspinal mass(57% vs 0%). Retropulsion of a bone fragment (benign cases 63% ; malignant cases 14%) was preferable forbenignancy. in addition, thin diffuse paraspinal mass (benign cases 15% ; malignant cases 14%) was seen.CONCLUSION: The morphologic and signal intensity characteristics seen on T1-weighted images were useful fordistingushing benign and malignant vertebral compression fractures. Fast spin-echo T2-weighted and fat-suppressedgadolinium-enhanced T1-weighted images played little role in distinguishing between the two.
