Abstract
Objective To investigate the clinical effect of minimally invasive internal fixation by pedicle screw through injury vertebra combined with bone graft in the treatment of thoracolumbar vertebral fractures.Methods 200 patients with thoracolumbar vertebral fractures admitted into our hospital from January, 2012 to January, 2014 were selected and randomly divided into an observation group and a control group, 100 cases for each group.The control group was treated with traditional open internal fixation by pedicle screw cross injury vertebra and posterior lateral bone grafting and fusion.The observation group was treated with minimally invasive vertebral pedicle bone grafting and internal fixation by pedicle screw through injury vertebra.The vertebral sagittal index, Cobb's angle, and the anterior height of vertebral body were observed before and after operation.The operation time, incision length, bleeding volume,postoperative drainage volume, postoperative hospital stay were evaluated in both groups.Results After the operation, the radiographic parameters [sagittal index (1.8±7.0) °, Cobb's angle (4.1±3.4) °, and vertebral height change (90.1±6.4)％] of the observation group were significantly better than those of the control group, with statistical differences (t =6.78, 6.80, and 7.02, P＜0.05).The operation time, incision length, bleeding volume, postoperative drainage volume, postoperative hospital stay were (142.0± 14.3) min,(10.9±1.8) cm, (105.8±12.4) ml, (5.6±4.1) ml, (6.5±1.0) d in the observation group and were (164.9±11.9)rmin, (16.1±1.6) cm, (506.1±101.4) ml, (386.8±87.8) ml, (9.6±2.7) d in the control group, with statistical difference (t =12.45, 8.90, 13.37, 16.70, 7.88, P＜0.05).Conclusions Minimally invasive internal fixation by pedicle screw through injury vertebra combined with bone graft in the treatment of thoracolumbar vertebral fractures is effective, safe, and reliable.关键词
