Objective: To evaluate the clinical effect of AF instrument in treating thora-cohtmbar fracture and to summarize the lesson of operation's fault. Methods : Fifty-four cases with thoracolumbar fracture were reviewed. Preoperative and postoperative of all patients,X-ray pictures, CT, MR and ASIA classification were studied and evaluated contrastively. Results: The main Cobb's angle of all 47 cases that had been followed up was corrected from 24. 5° preoperatively to 5. 5° post-operatively. Anterior height of compressed vertebral bodies restored from 53% preoperatively to 91% postoperatively. According to ASIA classification, the injury of nerves progressed 1-3 grade. The complications appeared in about 19. 1%. Conclusion- AF instrument can achieve anatomical reduction and stable interior fixation. It is one of the best devices for the treatment of thoracolumbar fracture. To improve the operators, surgical technique is the key in decreasing the complications.
