Abstract：Objective To evaluate the efficacy and prognosis of treating thoracolumbar burst fractures by subtotal vertebreectomy, titanium cage reconstruction and fixation with pedicle screw through posterior approach. Methods From Jun.2012 to Jun.2014,35 patients[21 males and 14 females aged from 26-45 years with an aver-age age of (37.4 ±6.3)years] with thoracolumbar burst fractures who were sleceted by thoracolumbar injury classi-fication and severity score system and loading sharing classification system,were treated by posterior subtotal resec-tion of vertebral body with implantation of titaium cage and distraction reduction fixation at one stage.Neurological status before and after operation and during the final follow-up was reviewed by American Spinal Injury Association (ASIA) scoring system.The distraction,occupation and fusion status were radiologically reviewed.Results All operations were carried out successfully.Cerebrosinal fluid leakage occurred in 6 patients and the others had no postoperative complications.All patients were followed up with an average of (15.3 ±6.8) months.Nervous func-tion improved in different degrees in 30 patients and 5 patients had the nervous function of grade A.Radiological re-sults showed satisfactory decompression and reduction after operation.All patients had complete bony fusion at the final follow-up without pseudathrosis.Conclusion It is an ideal operation method for the treatment of thoracolum-bar burst fractures by subtotal resection of vertebral body,reconstruction of the anterior and middle columns with tita-nium cage and fixation with pedicle screw through posterior approach.It has the advantages of convenient operation, less complications,thorough decompression and sufficient recovery of vertebral body height and canal volume.
