中位钉技术在单节段胸腰段骨折中的应用

Application of median pedicle screw technique in the single segmental thoracolumbar fracture

目的探讨中位椎弓根螺钉技术治疗单节段胸腰段骨折患者的临床疗效、并发症及随访结果。方法对2006年8月至2012年10月应用中位钉技术治疗的62例单节段胸腰椎骨折患者的临床资料进行分析。分析手术前、手术后、1年随访时伤椎前缘高度及矢状位Cobb角变化。结果术后所有患者的伤椎高度及Cobb角都得到明显恢复(P<0.05)。1年随访时,伤椎高度及矢状位Cobb角有轻度丢失,差异未见统计学意义(P>0.05),并发症少。结论中位钉技术在治疗单节段胸腰段骨折患者时可有效地恢复伤椎高度,重建前中柱的稳定性,能防止术后由于椎体高度丢失所导致的并发症,且临床疗效可靠,并发症少。

Objective To discuss the clinical efficacy,complications and follow-up results of median pedicle screw technique in the treatment of single segmental thoracolumbar fractures. Methods From August 2006 to October 2012,the clinical data of62 patients with single segmental thoracolumbar fractures underwent the median pedicle screw technique were analyzed. The anterior vertebral body height and changes of sagittal Cobb angle were analyzed before and after operation and 1 years of followup. Results The anterior vertebral body height and changes of sagittal Cobb angle was recovered in all patients（ P〈0. 05）. After 1 year follow-up,the injured vertebra height and Cobb angle were slightly lost,but the difference had no significant（ P〈0. 05）,and less complication. Conclusion Median pedicle screw technique in the treatment of patients with single segmental thoracolumbar fracture can effectively restore vertebral height, reconstructe the stability of the column, and prevent the postoperative complications due to loss of vertebral height with reliable clinical efficacy and less complications.
