ObjectiveTo explore the clinical effect of single segment of vertebral pedicle screw under Quadrant system in the treatment of thoracolumbar vertebral fracture. Methods80 patients with thoracolumbar vertebral fracture were divided into control group and study group according to the random number table,40 cases in each group. The patients in the control group were treated with open pedicle screw internal fixation, while the patients in the study group were treated with percutaneous pediculoplasty with Quadrant system. The clinical effect between the two groups were compared. ResultsThe incidence rate of complications in the study group was 10% (4/40), significantly lower than 20.0% in the control group (8/40), the difference was statistically significant (P＜0.05); Compared with the control group, the indexes of the perioperative period, the degree of activity of the intervertebral disc, the postoperative imaging parameters and the VAS scores of the study group were better than those of the control group, the difference was statistically significant between(P＜0.05). ConclusionThe clinical effect of percutaneous pediculoplasty under Quadrant system is better than open pedicle screw internal fixation in the treatment of thoracolumbar vertebral fracture, which can be used as an optimization scheme in clinic.
