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.
探讨球囊后凸成形术（BKP）的矫正量与相邻椎体骨折（AVF）的发生率是否相关。
分析61例无AVF患者和25例有AVF患者的数据。在椎体不稳定与矫正角度或高度之间使用线性回归模型，将患者分为过度矫正组和矫正不足组。
因不稳定而过度矫正的椎体骨折导致AVF发生率更高[角度和高度过度矫正时分别为42.4%和46.9%，而矫正不足时分别为10.7%和13.3%]。
骨折椎体的过度矫正可能与AVF发生率增加有关。
