摘　　要：目的　全面评估ＡＯ的通用脊柱内固定系统（ｕｎｉｖｅｒｓａｌ ｓｐｉｎｅ ｓｙｓｔｅｒｍ，ＵＳＳ）治疗胸腰椎骨折的疗效。方法　分析采用ＵＳＳ治疗胸腰椎骨折５６例患者的临床表现和影像学资料。结果　伤椎椎体前壁高度由术前的４４％恢复至术后的９１％，后壁高度由６２％至９４％，矢状面指数由２３．５°到４．２°，椎管内骨块矢状面占位由３７％到８％。脊髓神经恢复按ＡＩＳＡ分类，完全性脊髓损伤５例中，１例提高３级，４例无变化。不完全性脊髓损伤９例中，有１～２级的进步。结论　采用ＵＳＳ治疗胸腰椎脊柱骨折能得到满意的复位、牢固的固定和有效的椎管减压。Objective To comprehensively evaluate the clinical effect of USS (universal spine system) on unstable thoracoumbar spine fractures. Methods A total of 56 cases of unstable thora- columbar spine fractures treated with USS were reviewed. The X-rays,CT and clincal signs were examined and analyzed. Results The anterior height of the injuried vertebral body was meanly restored from 44% preoperatively to 91% postoperatively, the posterior height was from 62% to 94%, the sagittal index was corrected from 23.5° to 4.2°, and the sagittal spinal canal occlusion by the retropulsed bone fragments was meanly reduced from 37% to 8%. One of five cases with complete spinal cord injury was improved from grade A to D, the other 4 cases had no change. All of the cases with incomplete spinal cord injury were improved 1 - 2 grades. Conclusion USS instrumentation for unstable thoracolumbar fracture can obtain an satisfied reduction, rigid fixation and effective decompression of the injuried spinal canal.
