Comparison Of Clinical Outcomes Of Pedicle Screw Fixation Through Or Across Injured Vertebrae In Treatment Of Thoracolumbar Fracture

Objectives: To compare and investigate the efficacy of pedicle screw fixation through and cross the injured vertebra in treating thoracolumbar fractures.Methods: From December 2014 to January 2016,Retrospective analysis the clinical data of 62 patients with thoracolumbar compression fractures.According to internal fixation methods were randomized,of which 27 cases by the injured vertebral pedicle fixation as experimental group,35 cases across the injured vertebral pedicle fixation as control group,Analysis of two groups of patients with general information,There was no statistically significant difference.Compare two groups of patients with surgery related indicators,vertebral Cobb angle,anterior vertebral height and visual analog scores were evaluated for a long time.Results:1 Two groups of patients with surgery related data contrast,there was no statistically significant difference.2 In the aspects of Cobb angle,anterior vertebral height and visual analog scores,no significant difference was found between two groups of patients before treatment,but the experimental group is better than control group after treatment and at the time of the last follow-up,The difference is statistically significant(P<0.05).3 Statistical results suggest that the two fixation methods can more effectively reset injured vertebrae,can better correct the spinal deformity after injury,alleviate symptoms of pain,improve and restore the function of the patients.Compared with across vertebral injury group,Through injury vertebral group in restore and maintain the height and curvature of the spine has more obvious advantages,reconstruction of the spine physiological sequence and maintain its stability,effective control of low back pain.Conclusion: Compared with the traditional across injured vertebrae fixation,the internal fixation through the injured vertebrae can better reconstruction of spinal stability,restore and maintain the vertebral height and physiological curvature,which was an safe and effective therapy for thoracolumhar fracture.
