Abstract

• PURPOSE: To evaluate the efficacy of short segment fixation in flexion-distraction injuries of thoracolumbar junction. MATERIALS AND METHODS: Twenty-five patients with a flexion-distraction injury in thoracolumbar junction confirmed by radiogram or MRI and stabilized with a short construct spanning short segment were included in this study. We investigated the location of fractures, type of fractures, anterior or posterior vertebral body height, and preoperative and postoperative kyphotic angle of injuried motion-segments on radiologic examinations and clinical outcome on the Oswestry score. RESULTS: A significant correction of deformity was achieved, from a mean preoperative kyphosis of 17.3 degrees to a mean postoperative kyphosis of 8.4 degrees. The loss of correction were minimal. The mean Oswestry score was 6.9, with 84% of patients having minimal disability (<20%) and no correlation with age, sex, the location of fractures, type of fractures, change of kyphotic angle. CONCLUSION: This study demonstrates the efficacy of posterior open reduction and short segment fixation of flexion-distraction injuries.
