Abstract
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.
