摘　　要：目的探讨胸腰椎爆裂性骨折经伤椎椎弓根复位固定的可行性及原理。方法2004年3月至2008年3月对26例胸腰椎爆裂性骨折患者，给予伤椎及上下邻椎椎弓根固定治疗，并进行椎板切除减压，横突间植骨融合。结果术后椎体高度基本恢复正常，术后后凸角度基本纠正，经过6—22个月随访，未发现椎体高度丢失或内固定物折断。结论六钉法短节段固定治疗胸腰椎爆裂性骨折，具有复位好、固定牢固、防止术后椎体高度丢失，减少内固定的松动或断裂等优点。Objective To discuss the feasibility of pedicle instrumentation on the injured vertebrae for the reduction and fixation of thoracolumbar burst fractures. Methods All 26 cases of single thoracolumbar burst fractures received laminectomy decompression, intertransverse fusion and posterior transpedicular screw system internal fixation from March 2004 to March 2008. Both the cephalad vertebrae,the caudal vertebrae and the injured vertebrae were fixed. Results All the 26 cases were followed up for 6 - 22 months. All the injured vertebral body restored normal height and the kyphosis were corrected postoperatively. There were no such complications as the height of injured vertebrae loss, screw loosening or breaking. Conclusion Six - screw short segment pedicle instrumentation for thoracolumber burst fractures is effective in reduction and fixation of the injured vertebrae. And it may also prevent height lose of the injured vertebrae and the loose of screws.
