Abstract
To investigate whether the correction amount by balloon kyphoplasty (BKP) is associated with the incidence of adjacent vertebral fractures (AVF). Data from 61 patients without and 25 patients with AVF were analyzed. A linear regression model was used between vertebral instability and corrected angle or height to divide patients into the overcorrection and undercorrection groups. Vertebral fractures overcorrected for instability led to a higher incidence rate of AVF [42.4% and 46.9% with overcorrection vs. 10.7% and 13.3% with undercorrection for angle and height, respectively]. Overcorrection of fractured vertebrae may associate with the increased incidence of AVF.
