【摘要】 目的：分析后路椎弓根螺钉内固定术在治疗多节段胸腰椎骨折(MSF)中的临床价值。方法：选取32例MSF患者在全麻下行后路椎弓根螺钉内固定术，对比术前术后椎体高度和后凸角的改变，并进行Frankel评分，评估疗效。结果：根据随访结果，术前患者受损椎体前缘高度为(46.3±7.3)%，术后恢复到(92.8±4.5)%，治疗前后比较差异有统计学意义(t=30.6737，P<0.01)；术前后凸角为(30.3±5.4)°，术后为(7.8±2.9)°，差异有统计学意义(t=20.7652，P<0.01)。按照Frankel分级，多数患者的神经功能有明显的恢复。结论：后路椎弓根螺钉内固定术对MSF有较好的治疗效果，能够较好地恢复脊柱的稳定性，提高生存质量。

32 Cases of Multiple-Level Thoracolumbar Fracture Treated with Posterior Pedicle Screws Fixation/LIU Gang，QUAN Zheng-xue.// Medical Innovation of China，2012，9(23):016-017
【Abstract】 Objective:To analysis the clinical value of posterior pedicle screws fixation in treatment of multiple-level thoracolumbar fracture.Method:32 patients with MSF who were treated by posterior pedicle screws fixation under pamplegia were selected.The difference of vertebral body height，angle of kyphosis deformity before and after treatment were compared，and the Frankel score were done，to evaluate surgery efficacy.Result:According to the result of follow-up， the vertebral body height before operation was (46.3±7.3)% and the vertebral body height after operation was (92.8±4.5)% (t=30.6737，P<0.01). The angle of kyphosis was corrected from pre-operation (30.3±5.4)°to after operaion (7.8±2.9) °(t=20.7652，P<0.01). According to the Frankel score，the majority of patients’ neural function had apparent recovery. Conclusion:Posterior pedicle screws fixation has great treatment effectiveness for MSF.This can rebuilt the stability of spine and improve the quality of life.
