经后路椎弓根钉棒系统内固定治疗胸腰椎骨折的疗效观察

目的:探讨经后路椎弓根钉棒系统内固定治疗胸腰椎骨折的临床疗效.方法:将60例胸腰椎骨折患者,按手术编号末位数字奇偶随机分为观察组与对照组,各30例.对照组行传统椎弓根螺钉内固定术且未选后路入路,观察组行经后路椎弓根钉棒系统内固定术.对2组患者术后损伤椎体前后缘高度恢复、Cobb′s角矫正、椎管截面积改善及脊髓神经损伤情况进行统计学分析.结果:术前2组损伤椎体前后缘高度、Cobb′s角、椎管截面积及脊髓神经损伤差异均无统计学意义(P＞0.05),而术后2组患者上述指标较术前均有不同程度改善(P<0.05),且术后观察组改善情况优于对照组(P<0.05).结论:经后路椎弓根钉棒系统内固定治疗胸腰椎骨折疗效肯定,不仅固定可靠,且创伤小,值得临床推广应用.

The effects of posterior pedicle fixation system on thoracolumbar fracture

Objective:To investigate the clinic effects of posterior pedicle fixation system on thoracolumbar fracture.Methods:Sixty patients with thoracolumbar fracture were randomly divided into the observation and control group(30 in each group) according to the surgery serial number.The observation group were treated with posterior pedicle fixation system and the control group were treated with conventional pedicle screw fixation.The heights of anterior and posterior margin of vertebral centrum injuied,Cobb′s angle correction,the spinal canal cross-sectional area improved and the spinal nerves injuries of two groups after operation were statistically analyzed.Results:The heights of anterior and posterior margin of vertebral centrum injuried,Cobb′s angle,spinal canal cross-sectional area and spinal nerves injuries of two groups were no significantly different(P>0.05) at preoperation,and these data were improved to some extent at postoperation and the improvement of the observation were better than that of the control group(P<0.05).Conclusions:The clinic effects of treatment of thoracolumbar fracture with posterior pedicle fixation system are good,reliable and less trauma,which is worthy of being widely applied in clinic.
