后路椎体次全切钛网植骨重建治疗胸腰椎爆裂性骨折

目的探讨经后路椎体次全切、钛网植骨重建、椎弓根内固定治疗胸腰椎爆裂性骨折的疗效。方法对11例胸腰椎椎体爆裂骨折经后路椎体次全切、钛网植骨重建、椎弓根内固定。结果术后无神经症状加重及新的神经症状出现,伤椎Cobb角5°～15°（7.8°±0.5°）,X线脊柱序列基本正常。11例均获随访,时间4～30个月。末次随访时ASIA神经功能分级：B级3例均恢复至C级;C级6例恢复至D级5例、E级1例;D级2例均恢复至E级。结论经后路椎体次全切、钛网植骨重建、椎弓根内固定治疗胸腰椎爆裂性骨折神经功能恢复满意,是治疗胸腰椎爆裂性骨折的较好方法。

Treatment of thoracolumbar burst fracture by subtotal resection of vertebral body, implantation of titanium cage reconstruction through posterior approach

Objective To investigate the effect of treating thoracolumbar burst fracture by subtotal resection of vertebral body, implantation of titanium cage reconstruction, pedicle screw internal fixation through posterior approach. Methods Eleven patients with burst thoracolumbar fi＇aeture were treated by posterior subtotal resection of vertebral body,implantation of titanimn cage reconstruction, pedicle screw internal fixation. Results After a follow-up of 4 - 30 months,none of the neuropathic symptoms increased. The Cobb＇s angle of injured vertebrae was less than 5° -15° （7.8°±0. 5°）. X-ray revealed the vertebral column sequence was normal. 11 patients were followed up for 4 to 30 months. According to resuhs of the last follow-up about ASIA neurological level：3 patients recovered from B level to C level;5 patients recovered from C level to D level;1 patient recovered from C level to E level;2 patients recovered from D level to E level. Conclusions The neural function can be recovered by subtotal resection of vertebral body, implantation of＇ titanium cage reconstruction and internal fixation. The posterior approach is a better treatment of thoracolumbar burst fracture.
