    ¡¾Abstract¡¿ AIM: To evaluate the correction degree of spine after posterior reduction, graft fusion and fixation of the upper adjacent intervertebral space in the treatment of thoracolumbar flexion compression fractures. METHODS: Twentyª²three patients with thoracolumbar flexion compression factures underwent the operation of posterior reduction, graft fusion and fixation of the upper adjacent intervertebral space. The preoperative and postoperative imaging findings were summarized and the results were analyzed. RESULTS: All cases were followed up for a period of 12 months. The mean height of anterior margin of injured vertebral bodies was 19 mm before surgery, and respectively corrected to 31 mm and 29 mm at the time of 1 week and 12 months after surgery. The mean of Cobb¬ðs angle was 21¡ã before surgery and respectively corrected to 6¡ã and 9¡ã at 1 week and 12 months after surgery. CONCLUSION: Posterior fixation of single intervertebral space for treatment of patients with thoracolumbar flexion fractures can achieve a good reduction. Loss of correction degree is a little during the longª²term followª²up. Besides, it can keep the function of other intervertebral spaces as much as possible. ......
