1、伤椎椎弓根螺钉固定横突间植骨治疗胸腰段爆裂骨折作者：齐祥如，冯虎，马志兵，龚维成，郭开今【摘要】目的评价经伤椎行椎弓根螺钉固定结合横突间植骨治疗胸腰椎单节段椎体爆裂性骨折的临床疗效。方法回顾性分析我院XX年6月至XX年1月期间经伤椎行椎弓根螺钉固定结合横突间植骨治疗胸腰椎爆裂性骨折病例资料16例，其中男性11例，女性5例；年龄21〜68岁，平均岁。收集的病例均为单节段椎体爆裂性骨折，伤椎仅一侧椎弓根置钉，即五钉固定法。比较术前术后椎体前缘高度、脊柱后凸角（矢状面Cobb's角）、椎管正中矢状径、神经功能Frankel分级等指标。结果术后随访6〜24个月，平均随访个月，术后均获得较好复

2、位，高度及外形基本恢复正常，无内定物松动、断裂等并发症，手术前后椎体前缘高度、脊柱后凸角（矢状面Cobb's角）、椎管正中矢状径比较差异均有统计学意义（P＜），疼痛明显减轻，神经功能Frankel分级亦有改善。结论经伤椎行椎弓根螺钉固定结合横突间植骨治疗胸腰椎椎体爆裂性骨折可获得不错疗效，可以较好重建椎体高度，减少并发症，增强固定的稳定性及抗扭转能力，是治疗胸腰段椎体爆裂性骨折一种可行、有效的方法。【关键词】胸腰段；伤椎；植骨；爆裂性骨折Abstract:ObjectiveToevaluatetheclinicaloutcomeofthetreatmentofthoracolumba
