摘要 目的评价术前采用Photoshop(PS)辅助截骨设计在创伤后陈旧性胸腰椎后凸畸形矫正中的应用价值。方法回顾性分析自2012—03—2015—03采用改良PSO截骨矫形术治疗的18例创伤后陈旧性胸腰椎后凸畸形。于PACS系统测量局部伤椎后凸角(RK)、全脊柱后凸角(GK)及矢状位垂直轴(SVA)。将术前X线片导入PS软件进行截骨模拟和截骨角度计算。结果18例均获得随访13—32个月.平均21.5个月。切口均一期愈合。末次随访时X线片显示截骨部位骨性融合良好,未发现内固定失效及断裂。术前计划截骨角度为(33.7±9.7)°,术后实际截骨角度为(34.2±10.5)°,差异无统计学意义(t=0.84,P=0.42)。末次随访时VAS评分、ODI指数、SVA、GK、RK较术前明显改善,差异有统计学意义(P〈0.05)。术后3d各观察指标与末次随访时比较差异无统计学意义(P〉0.05)。结论PS软件截骨设计应用于创伤后陈旧性胸腰椎后凸畸形矫正,能够精准矫正患者局部后凸畸形和脊柱矢状面平衡。
