椎弓根钉内固定治疗多节段胸腰椎骨折

目的探讨多节段胸腰椎复杂骨折手术治疗效果。方法采用后路长节段椎弓根钉系统复位固定方法,恢复伤椎高度及脊柱生理弯曲,使后纵韧带复张,椎管间接减压或有限椎板切除减压、植骨融合治疗胸腰椎多节段骨折21例。结果术后椎体高度、脊柱生理弧度明显恢复。21例均获随访,时间3个月～6年。椎体高度无明显丢失,无断钉、断棒。Frankel分级：A级2例恢复至B级1例、1例无恢复;B级3例恢复至C级1例、D级1例、1例无恢复;C级5例恢复至D级3例、E级2例;D级5例恢复至E级3例、2例无恢复;E级6例仍为E级。结论多节段胸腰椎骨折影响脊柱稳定性,后路长节段椎弓根钉系统复位固定能够恢复脊柱稳定性及生理弧度,为改善神经功能提供条件。

Pedicle screw fixation for multiple-level thoracolumbar fracture

Objective To observe the effect of surgical results of multiple-level spinal fractures.Methods 21 cases of multiple-level spinal fractures were surgically treated through posterior approach by open reduction,internal fixation with pedicle screw-rod spine instrumentation,limited vetebral canal decompression and posterolateral fusion with bone graft to restore injury vertebral height.Results All cases were followed up for 3 months to 6 years.The fractured vertebra height and spinal physiological curve were im...
