【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(P0.05)。术后3 d各观察指标与末次随访时比较差异无统计学意义(P0.05)。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。
[Abstract]:Objective to evaluate the value of preoperative Photoshop (PS) assisted osteotomy in correction of posttraumatic thoracolumbar kyphosis. Methods 18 cases of posttraumatic thoracolumbar kyphosis treated with modified PSO osteotomy from 2012-03 to 2015-03 were retrospectively analyzed. Measurement of kyphosis angle (GK) and sagittal vertical axis (SVA). In local injured vertebrae kyphosis angle (RK), total kyphosis angle and sagittal axis (SVA). By PACS system The preoperative X-ray films were imported into PS software for osteotomy simulation and osteotomy angle calculation. Results all 18 cases were followed up for 13 ~ 32 months (mean 21.5 months). All the incisions healed at the first stage. At the last follow-up, X-ray showed that the osteotomy site had a good bone fusion, and no internal fixation failure or fracture was found. The planned osteotomy angle was (33.7 卤9.7) 掳before operation, and the actual osteotomy angle was (34.2 卤10.5) 掳after operation. At the last follow-up, VAS score, ODI index and SVA,GK,RK were significantly improved compared with those before operation (P0.05). There was no significant difference between the observed indexes at 3 days after operation and that at the last follow-up (P0.05). Conclusion the PS software osteotomy can be used to correct the local kyphosis and sagittal balance of posttraumatic thoracolumbar kyphosis.
