目的 探讨伤椎置钉单节段内固定植骨治疗胸腰段脊柱骨折的临床疗效.方法 回顾性分析2009年5月~2012年5月收治的86胸腰段脊柱骨折患者,均采用伤椎置钉单节段内固定植骨融合治疗,根据内固定方式不同分为椎弓根螺钉脊柱内固定系统(AF)组(46例)和通用型脊柱内固定系统(GSS)组(50例),前者采用椎弓根螺钉脊柱内固定系统进行治疗,后者采用通用型脊柱内固定系统进行治疗,最后比较两组的临床疗效.结果 两组患者术后椎前后缘高度均显著高于术前,而术后Cobb角均显著低于术前,组内比较差异有高度统计学意义(均P < 0.01),而组间无论是术前还是术后比较差异无统计学意义(P > 0.05);但GSS组患者手术时间和术中出血量均显著少于AF组,组间比较差异有高度统计学意义(P < 0.01).结论 AF及GSS的临床应用效果相近,尤以GSS的治疗效果更优,具有操作简单、手术时间短、术中出血量少、安全性高、复位效果佳等众多优点,值得临床广泛推广应用.%Objective To evaluate the clinical effect of the treatment of thoracolumbar spine fractures with injured vertebral pedicle screw monosegmental internal fixation and bone graft fusion. Methods The clinical data of 96 patients of thoracolumbar spine fractures who were treated with injured vertebral pedicle screw monosegmental internal fixation and bone graft fusion from May 2009 to May 2012 were analyzed retrospectively, and were divided into two groups based on different internal fixations. The group AF (46 cases) were given the AF pedicle screw fixation, and the group GSS (50 cases) were given GSS pedicle screw fixation. Results The anterior and posterior of vertebral height and the recovery of Cobb's angle were all significantly improved after the operations (P < 0.01), but there were no significant difference of later clinical effect between two groups (P > 0.05). Besides, the operative time and blood loss of the group GSS were significant less than that of the group AF (P < 0.01). Conclusion The clinical effect of the application of GSS in treatment of thoracolumbar spine fractures is close to that of AF. Particularly with GSS internal fixation, it's easy to operate, showing the advantages of time-saving, bleeding amount reducing and stable fixation, etc. Thus is deserving clinical application.
