摘要
目的评价Kaneda内固定装置与Z-plate内固定钢板系统治疗胸腰椎严重爆裂骨折的疗效。方法回顾分析62例前路减压、植骨加内固定术治疗的胸腰椎严重爆裂性骨折伤员,其中Kaneda内固定30例;Z-plate钢板内固定32例。结果两组伤员平均手术时间、平均手术出血量Z-plate组与Kaneda组比较,两组之间的差异有显著性(P<0.05)。62例患者均获得随访,平均随访6.6个月(6￣20个月)。术后平均植骨融合时间、术后长期后凸矫正度丢失Z-plate组与Kaneda组比较,两组之间的差异无显著性(P>0.05)。两组伤员手术前后神经功能恢复情况(占小组例数),术后与术前比较差异有显著性(P<0.05)。术后Z-plate组与Kaneda组比较差异无显著性(P>0.05)。结论两种前路手术内固定器均具有良好的减压、固定效果。Z-plate内固定钢板系统较之Kaneda固定装置手术操作简单,植入方便,可减少手术时间及手术出血量。
[Objective] To evaluate the outcomes of the treatment of severe burst fractures of thoraco-lumber spine with the use of anterior internal fixation apparatus system. [Method] Sixty two cases suffered from severe burst fractures of thoraco-lumber spine after trauma between 1999 and 2004 were divided into 2 groups according to the use of different anterior internal fixation apparatus system. Group Kaneda including 30 cases were managed by anterior decompression, autograft and Kaneda device internal gxation. Group Z-plate including 32 cases were managed by anterior decompression, autograft and Z-plate instrument internal fixation. [Result] The differences of average operative time and average amount of bleeding during operation between Group Z-plate and Group Kaneda had statistical significance （P 〈0.05）. After an average duration of 6.6 months of follow-up ranging from 6 to 20 months, the differences of average interbody fusion time postoperative and the lose lyphosis postoperative between Group Z-plate and Group Kaneda had no statistical significance （P〉0.05）. The recover of neural function resulted from operation, the differences of neural function within the two groups themselves between postoperative and preoperative had statistical significance （P 〈0.05）. That between the two groups postoperative had not statistical significance （P 〉0.05）. [Conclusion] Anterior decompression, grafting and internal fixation can provide feasible effective decompression and strong fixation leading to excellent graft fusion. The Z-plate instrument system has more advantages than the Kaneda device system, such as easier and safer manipulation, with less amounts of bleeding, and shorter operative time.
