摘要
目的 探讨经伤悱单侧椎弓根固定治疗胸腰椎骨折的可行性和临床疗效。方法 回顺性分析2005年1月到2010年12月应用后路椎弓根螺钉技术治疗的98例腼腰椎骨折心行的临床资料．男，66例．女 32例；年龄19～65岁．平均心44．9岁。根据治疗办法不同分为经伤椎单侧椎弓根固定组（经伤椎组，50例）和短节段椎弓根固定组（矩节段组，48例）、比较两组忠者的手术时间、术中出血量及术前、术后cobb 角 伤椎前、后缘高度、内固定失败率。结果 所有患者术后获6-53个月（平均34个月）随访。两组患者手术时间、术中出血量比较差异无统计学意义（P〉0．05）．结论 经伤椎单椎弘侧椎弓根吲定治疗胸腰椎骨折能提供较单纯短节段椎弓根固定更好的复位效果和更为坚固的内固定强度。
