经椎弓根植骨椎体成形内服续骨活血汤治疗胸腰椎爆裂性骨折22例

目的：观察经椎弓根椎体成形内服续骨活血汤治疗胸腰椎爆裂性骨折的临床疗效。方法：自2006年7月至2010年3月期间采用后路椎弓根螺钉固定加经椎弓根植骨椎体成形内服续骨活血汤治疗胸腰椎爆裂性骨折共22例，随访时间为3～20个月，平均12个月，观察术前术后椎体高度、Cobb角及椎管矢状径变化情况。结果：22例患者术后随访未见内固定物失败，椎体矫正度丢失经分析无统计学意义。结论：经椎弓根植骨椎体成形配合续骨活血汤内服能在椎管减压和恢复椎体高度的同时重建了椎体的前中柱，使椎体重获生物学稳定，有效减少内固定应力，降低内固定的松动、断裂和远期椎体高度的丢失，促进骨折的愈合。

Clinical Observation on Vertebrae Implantation via Vertebral Arch Combined with Xugu Huoxue Decation in Treating Thoracolumbar blow out Fracture

To observe the effects of vertebrae implantation through vertebral arch and Xugu Huoxue Decoction for treatment of thoracolumbar blow out fracture. Methods:From the July of 2006 to the March of 2009, 22 patients with thoracolumbar blow out fracture, underwent fixation of posterior vertebral arch by pedicle screw and implantation vertebrae through vertebral arch and took Xugu Huoxue Decoction. They were followed up time between 3 to 20 months, with an average of 12months. The vertebral height before and after the operation, the angle of Cobb, and the changing of the sagittal diameter of vertebral canal were observed. Results:No fixture failure is seen in the 22 patients after operation during the follow up time. There was no statistical significance in terms of the loss of the vertebral correction. Conclusion:Implantation vertebrae through vertebral arch and Xugu Huoxue Decoction can reconstruct the anterior and middle column, and decompress the vertebral canal and rebuild the vertebral height. As a result, the vertebrae regains its biological stability. Moreover, this treatment has efficiently reduced the internal fixation stress, the risk of the looseness and break of internal fixture and the loss of vertebral height in the long term, therefore, improves heeling of bones.
