Effect of minimally invasive transpedicular bone grafting additional vertebral pedicle screw fixation in the treatment of thoracolumbar fracture

Abstract

Objective To explore the effect of minimally invasive transpedicular bone grafting additional vertebral pedicle screw fixation in the treatment of thoracolumbar fracture. Methods 60 patients with thoracolumbar fracture were randomly divided into the observation group and the control group,30 cases in each group. The control group received traditional open inter vertebral four nail pedicle screw fixation combined with posterolateral bone graft fusion for treatment while the observation group was treated by minimally invasive transpedicular bone grafting additional vertebral pedicle screw fixation,to analyze the clinical effects. Results The imaging parameters of postoperation[the sagittal index(1.9±7.1)°,Cobb's angle(4.2±3.5)°, change of vertebral body height(90.2 ±6.5)%]in the observation group were significantly better than those of the control group(t= 6.78,6.80,7.02,all P<0.05).The imaging parameters 3 months after operation[the sagittal index(4.9±3.2)°,Cobb's angle(7.0±2.7)°, change of vertebral body height(87.6±4.1)%]in the observation group were significantly better than those of the control group(t = 6.78,6.80,7.02,all P<0.05).The operation time,incision length,bleeding volume,postoperative drainage,postoperative hospital stay of the observation group were(141.9±14.2)min,(10.8±1.7)cm,(105.7±12.3)mL,(5.6±4.1)mL,(6.6± 1.1)d,respectively, which were significantly better than those of the control group(t= 7.72,7.89,5.68,all P<0.05). Conclusion Minimally invasive transpedicular bone grafting additional vertebral pedicle screw fixation has a significant effect in the treatment of thoracolumbar fractures, which is safe and reliable.
