The Clinical Efficacy Of Thoracolumbar Burst Fracture Of Vertebral Pedicle Screw System For Treatment

Porpuse By studying the clinical effect of whether or not fixing pedicel screw in injured vertebra for treatment of the single thoracolumbar burst fracture without spinal cord injuryed, discusses the advantage of fixing pedicle screw in Injured vertebra for it.Method Retrospective study47patients with single thoracolumbar burst fractures with no nerve damage were treated in chengdu university of traditional Chinese medicine affiliated hospital,the first people’s hospital of liangshan prefecture, while luzhou in TCM hospitals, nanchong hospital treatedin2011-2012, including21cases treated by fixing pedicle screw in Injured vertebra (group A),26cases treated by traditional injured vertebral pedicle screw fixation (group B). All of the patients were fresh fractures, and were not associated with nerve damage, and one side pedicle was complete at least. Recording of how much time operation needed, how much blood lost, the relative height and Cobb Angle of the fanterior edge and the trailing edge of Injured vertebral before the operation, after the operation immediately and1year after the operation In the X-ray shows. Calculating how much height of the fanterior edge and trailing edge and Cobb Angle of Injured returned after the operation immediately, and how much height of the fanterior edge and trailing edge and Cobb Angle of Injured returned lost1year after operation. Comparing and analyzing the data, to evaluate the effect of two waysResult T test was carried out on the collected data. Comparing the two groups of patients with operation time, group A needs more time for operation than group B, P<0.05, the difference was statistically significant; Comparing the two groups of patients with lost blood group A is more Serious than group B, P<0.05,the difference was statistically significant;Comparing the two groups of patients with injury vertebral height restoration and Cobb Angle correction degrees after the operation Immediately, P>0.05, of no statistical significance. Comparing the two groups of patients with injured vertebral height lost degree and Cobb Angle correction lost1year after the operation, group A is much smaller than group B, P<0.01, and the difference was statistically significant. Group A has1case of thoracic lumbar back pain, no fracture and loosening of internal fixation, group B has4cases with thoracic lumbar back pain or the pain of lower limbs numbness,2cases with loosing nut, no fracture or emergence.Conclusion For a single thoracolumbar burst fracture, fixing pedicle screw in injured vertebra needs more time and losses more blood than fixing pedicle screw across injured.The resetted effect of two ways is similar. The fixed stability of fixing pedicle screw in injured vertebra is more stronger than fixing pedicle screw across injured1year after operation.The group of fixing pedicle screw across injured had the situation of Internal fixation loosening1year after the operation, but the other group had not. The two groups had the situation of Lower back pain,but the group of fixing pedicle screw in injured vertebra was less than the other one1year after the operation...
