【摘要】目的:探讨采用AF椎弓根钉复位固定有限减压自体骨行椎体成形术治疗新鲜胸腰椎骨折的结果。方法:50例新鲜胸腰椎骨折先行椎弓根钉固定,后路有限减压骨块复位,后经椎弓根向复位椎体内植入自体骨颗粒。结果:术后椎体高度和生理弧度恢复满意,未有神经症状加重,经随访椎体高度和生理弧度无丢失、无固定松动、断裂。结论:椎弓根钉系统内固定加自体骨植骨椎体成形术安全,效果满意,价格低廉,值得应用。

Abstract Objective: To evaluate the e of surgical treatment of the thoracolumbar fracture in early stages with pedicle screws (AF). Methods: The thoracolumbar vertebrae fracture was fixed with pedicle screws in 50 patients, with the bone reduced by posterior limited pression, and then the bone autograft granule was implanted into the reduced vertebral body through pediculus arcus vertebrae. Results: Recovery of the height and physiologic radian of vertebral body was satisfactory after the surgery, with no aggravation in clinical nerve symptoms, and follow-up examination showed that there were no loss in the height and physiologic radian of vertebral body, no loosing in fixation and no repeated fracture in vertebrae. Conclusion: Surgical Treatment of thoracolumbar fracture with pedicle screw AF is safe, effective, less expensive and worth wide application in clinics.

目前对于胸腰椎骨折的治疗大都是椎弓钉内固定(AF),后侧椎板减压,撑开复位,横突间或小关节突间植骨。至少需要融合2个以上节段,造成邻近节段的退变,且后路植骨属于张力侧植骨,发生不融、吸收的比例高。针对上述的特点,用经伤椎椎弓根植骨椎体成形替代后路植骨的治疗方式正逐
