后路切开复位短节段椎弓根钉内固定治疗胸腰椎骨折

Result of Thoracolumbar Fractures Treated with Short-segment Pedicle Instrument

目的:探讨后路切开复位短节段椎弓根钉内固定对胸腰椎骨折的治疗效果。方法:临床治疗胸腰椎骨折132例,均采用后路Dick钉或AF椎弓根钉内固定,比较术后骨折复位及神经功能恢复情况。结果:术后椎体高度完全或基本恢复占95.5％,神经功能恢复1级或以上占91.9％,有断钉、松动及矫正度丢失现象。结论:后路切开复位短节段椎弓根钉内固定及治疗胸腰椎骨折的有效方法,但也存在一些问题。

Objective: To analyze the results of thoracolumbar fractures treated with short-segment pedicle instrumentation. Methods: 132 cases of thoracolumbar fractures were treated with AF or Dick instrumentation. Comparison with thoracolumbar postural contour restoration and facilitates neural recovery after operation was taken. Results: Vertebral body height improved complete recovery or almost in 95 .5% of patients, neurological status improved at least 1 Frankel grade in 91.9% of patients. But it was associated with implant failure correction loss and break of screwscad and loosen of screw. Conclusion: Short-segment pedicle instrumentation provided satisfying stability for thoracolumbar fractures. But there were some problems.
