Abstract:

Objective To compare the clinical effect of injured vertebra mono ⁃ segmental fixation and across injured vertebra shortsegmental fixation in the treatment of thoracolumbar fractures. Methods From March 2015 to March 2018，90 patients with thoracolumbar fractures in our hospital were selected and randomly divided into observation group（n = 45）and control group（n = 45）. Patients in the observation group were treated with injured vertebra mono⁃segmental fixation，while patients in the control group were treated with across injured vertebra short segmental fixation. All of patients were followed up for 24 months. The anterior height ratio of injured vertebral body， sagittal Cobb angle，loss of correction，operation time，blood loss，incision length，quality of life and postoperative complications were compared between the two groups. Results There were no significant differences in operation time and quality of life between two groups（P > 0.05）. There were significant differences in postoperative complica⁃ tions，blood loss，incision length and quality of life at the last follow⁃up between the two groups（P < 0.05）. The quality of life，anterior vertebral height and Cobb angles were significantly restored in both of two groups，but the last follow ⁃ up，the anterior height and sagittal Cobb angle of the fractured vertebra body in the mono ⁃ segment fixation group were better than those in the across injured vertebra short segment fixation group，and the difference was statis⁃ tically significant（P < 0.05）. Conclusions The short ⁃term and medium ⁃term clinical effect of injured vertebra mono⁃segment fixation in the treatment of thoracolumbar fractures is better than that ofacross injured vertebra short segmental fixation，causes less trauma and complications.
