ABSTRACT
Objective To explore the clinical curative effect of AF system combined vertebra re-duction and posterolateral bone fusion treatment thoracolumbar burst fracture .Methods Seventeen pa-tients with thoracolumbar burst fracture using period stage , according to the system of AF clinical symptoms and image data line pressure decreased , and the pressure or not to hurt inside the vertebral pedicle autoge-nous bone grafts are grain filling and vertebral posterolateral line between the axon , lamina around small joints and bone , and postoperative follow-up X-ray inspection regularly , observe internal fixation and verte-bral vertebral height and adjacent intervertebral space changes , or after fixation and reset lost .Results following up 13 months, vertebral body height restore and maintain good , bolt looseness and broken and ver-tebral body height complications such as lost were no found in 17 cases.Conclusion Treatments of Poste-rior fixation combined short stage AF vertebral body and posterolateral bone fusion on thoracolumbar burst fracture are not only rebuild the vertebral height , but also make the vertebral obtained after three pillars in stable, reduce the internal fixation and compressed vertebral again such complications .
