经椎弓根椎体植骨及AF内固定治疗重度胸腰椎压缩性骨折

Treatment of the serious compressive thoracolumbar spinal fractures with transpedicular intracorporeal grafting and AF internal fixation

目的 :探讨经椎弓根椎体植骨在重度胸腰椎压缩骨折中的作用和远期疗效。方法 :采用经椎弓根椎体植骨 ,AF系统复位、内固定治疗胸腰椎骨折 32例 ,术前、术后及随访时摄X线检查 ,测量观察椎体高度有无丢失 ,内固定有无断裂、松动情况发生。结果 :全部随访病例未出现明显的椎体高度的再丢失 ,无一例发生内固定断裂、松动。结论 :重度胸腰椎压缩骨折经椎弓根椎体植骨、AF内固定后 ,可恢复伤椎椎体高度 ,重建前中柱的稳定性 ,防止术后椎体的再丢失和内固定的松动、断裂。

Objective:To study the role and long term results of transpedicular intracorporeal grafting in the treatment of serious compressive thoracolumbar fractures.Methods:32 patients with thoracolumbar fractures were treated with transpedicular intracorporeal grafting,combined with AF reduction and fixation.The height of the injured vertebrae was measured and the internal fixation was observed through the preoperative and postoperative X-ray.Results:All cases were followed up 12,2months in average.The height of vertebral body didn′t obviously reduce and the internal fixation didn′t break and loose at all.Conclusion:The method that the thoracolumbar fractrues were treated with transpedicular intracorporeal grafting and AF fixation can recover the height of the injured vertebrae,reconstruct the stability of the anterior and middle columnm,prevent the reduction of the vertebrae′s height and the breakage of the internal fixation postoperatively.
