经伤椎椎弓根内固定联合椎间植骨融合术在下腰椎爆裂性骨折治疗中的应用

[目的]探讨经伤椎椎弓根内固定联合椎间植骨融合术在下腰椎爆裂性骨折治疗中的应用价值。[方法]采用经伤椎椎弓根内固定联合椎间植骨融合术治疗下腰椎爆裂性骨折,并比较手术前后X线检查和脊髓神经恢复情况。[结果]在随访期间复查128例患者的X射线片显示内固定位置良好,未出现螺钉松动、断钉、断棒等现象;未发生感染、排异等不良反应;椎体前缘高度、椎体后缘高度及Cobb角与术前比较有明显差异,且差异具有统计学意义(P﹤0.05)。这表明伤椎高度、生理曲度恢复良好;随访期间伤椎椎体高度、脊椎序列及椎管形态维持良好。CT平扫显示椎管内骨块复位良好,伤椎经撑开复位后的空隙被植骨充填;神经功能不全损伤患者均有不同程度功能恢复。[结论]经伤椎椎弓根内固定联合椎间植骨融合术不仅能复位骨折,重建脊柱高度,而且能提供晚期脊柱的稳定性,防止高度丢失,减少内固定并发症,是一种较为理想的治疗方法。
