摘要目的 研究后路短节段内固定联合伤椎置钉治疗胸腰段单椎体骨折的即时效果.方法 收集了2006年7月至2008年8月间收治的胸腰段脊柱骨折病例共62例.A组共35例,采用跨阶段固定;B组共27例,采用短节段联合伤椎置钉固定.测量手术前后X线片,比较节段后凸角度变化和骨折椎体高度、骨折椎体复位率的组间差异.结果 所有62例患者均顺利完成手术.两组间骨折椎体高度、骨折椎体复位率差异有统计学意义[(84.2±2.8)vs(98.6±1.9),P<0.05],节段后凸角度的变化差异无统计学意义[(8.5±1.0)vs(8.1±1.3),P>0.05].结论 短节段固定联合伤椎置钉有助于骨折椎体高度的恢复,对于治疗胸腰段单椎体骨折具有较好的即时效果.

abstractsObjective To observe the early clinic outcome of treating thoracolumbar mono-segmental fracture with posterior fixation in combination with intermediate screws. Methods From July 2006 to August 2008, 35 of 62 patients with thoracolumbar mono-segmental fracture were treated with in Croup A and the remaining 27 with intermediate screw in combination with short segmental fixation in Croup B. Results The relative height of fractured vertebrae and reduction rate showed significant differences [(84.2±2.8 )vs (98.6 ± 1.9) ,P <0.05] between two groups while the change of segmental kyphotic angle showed no difference [ (8. 5 ± 1. 0) vs(8. 1 ± 1.3) ,P >0.05]. Conclusion Intermediate screw in combination with short segmental fixation has a better immediate efficiency in treating thoracolumbar mono-segmental fracture since it reduces the height of fractured vertebrae.
