后路经伤椎六钉固定结合后外侧自体骨植骨融合治疗胸腰段骨折56例临床评价

Clinical Evaluation of Posterior Short-segment Pedicle Screw Fixation at the Injured Level,with Posterolateral Fusion for Thoracolumbar Spine Fractures 56 casas

[目的]探讨后路短节段经伤椎六钉固定结合后外侧自体骨植骨治疗胸腰段骨折的临床疗效。[方法]回顾性研究2006年6月至2010年6月期间,本院行传统跨伤椎4钉固定后外侧羟基磷酸钙植骨融合组(A组)60例。行经伤椎6钉固定后外侧自体骨植骨融合组(B组)56例。[结果]经统计学处理,B组的末次随访时复位丢失率小于A组。A组内固定失败率高于B组,植骨融合率低于B组,三组P值均<0.05。[结论]后路短节段经伤椎六钉固定结合后外侧自体骨植骨融合术是治疗胸腰段压缩性和中轻度爆裂性骨折的一种经济有效安全的方法。

[Objective]To discuss clinical outcome of posterior short-segment pedicle fixation at the injured level for treatment of thoraeolumbar spine fractures.[Methods]Clinical data about patients admitted to our department from June 2006 to June 2010 were retrospectively analyzed.The patients were divided into 4-screw fixation group(n=60)and 6-screw fixation group(n= 56).[Result]Compared with the loss of reduction,implant failure rate was more lower in 6-screw fixation group than in 4-screw fixation group after operation,expert the fusion rate.[Conclusion]Posterior short-segmental fixation at the injured level with posterolateral fusion is cheaper,effective and safe procedure for compression fractures and mild to moderate burst fractures of the thoracolumbar spine.
