摘要
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。
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 improved. No implant failure and kyphosis deformity was found. According to the Frankel grading system：l case improved from A to B in 2 patients, the other wasn＇t improved; 1 case improved from B to C, and 1 case improved from B to D in 3 patients, 1 case wasn＇t improcved; 3 cases improved from C to D, and I case improved from C to E in 5 patients; 3 cases improved from D to E in 5 patients; the others wasn＇t improved. But none improved in 6 cases with Frankel E. Conclusions Multiple-level spinal fracture affects spinal stability. The posterior open reduction and internal fixation with pedicle screw-rod spine instrumentation im- prove spinal stability and spinal physiological curve, which prvides a choice for improving neural function.
