椎弓根钉内固定系统治疗胸腰椎骨折合并脊髓损伤

目的探讨椎弓根钉内固定系统治疗胸腰段骨折合并脊髓损伤的效果。方法对46例胸腰段骨折合并脊髓损伤的患者，进行椎板切除、椎管减压、椎弓根钉系统内固定加植骨术，并对术后神经功能恢复、椎体高度恢复及椎管截面积进行分析。结果随访8-36个月，平均20个月，神经功能平均恢复1．6级，椎体高度平均恢复到正常高度的95％以上，无一例术后神经功能障碍加重。结论早期椎板切除、椎管减压、椎弓根钉系统内固定是治疗胸腰段骨折合并脊髓损伤有效的手术方式。

Pedicle screw system in the freatment of thoracolumber fractures and spine cord injnries

Objective To evaluate the clinical effects of pedicle screw system in the treatment of thoracolumbar fractures and spine cord injuries . Methods A total of 46 cases with thoracolumbar fractures and spine cord injuries were reviewed. All patients were treated by pedicle screw system. Their clinical signs, X-ray and CT before and after operation were analyzed. Results With mean follow-up of 20 months （ 8 - 36 months）, the neurological function recovered 1.6 grades , the height of compressed vertebral bodies was restored more than 95 % postoperatively, no case occurred severe neurological complication. Conclusion Pedicle screw system is an effective method for thoracolumbar fractures and spine cord injuries.
