Abstrakt:	Background: There is some controversy about which is the best approach, decompression technique and number of fixed levels in the surgical treatment for burst thoracolumbar fractures. Without a neurological injury, correcting thoracolumbar kyphosis and preventing mechanical failure should be the main concerns. The two-segment short fusion with screws at fractured vertebra by posterior approach was performed in 64 patients. Although a significant increase of postoperative kyphosis was observed, there were not clinical consequences, nor was there reintervention for mechanical failure. Methods: Patients with unstable T11-L2 burst fractures and a two-level fusion including screws at the injured vertebra between 2000 and 2015 were included in the study. Demographic, clinical, and radiological variables were analyzed. Thoracolumbar, segmental, and vertebral kyphosis and anterior and posterior vertebral height were measured preoperatively, postoperatively, at one-year, and at the end of follow-up in the radiological study. The statistical analysis consisted of a descriptive analysis, and we used the t test to compare the preoperative, postoperative, one-year, and end-of-follow-up radiographs to observe a thoracolumbar T10-L2 kyphosis increase. Significance level was established at P < .05. Results: Fifty-four patients were included. A statistically significant increase of vertebral, segmental, and thoracolumbar kyphosis ( P < .05) was observed during follow-up, without clinical consequences. Conclusions: Two-segment fusion is an effective technique and allows initial deformity kyphotic correction after thoracolumbar burst fracture. The thoracolumbar kyphosis increased during the follow-up, without pain, disability, or mechanical failure. Level of Evidence: 2a.
