Clinical effect of pedicle screw internal internal vertebra grafting fixation vertebra bone grafting on patients with thoracolumbar fracture

Objective To study the clinical effect of pedicle screw internal fixation vertebra grafting on thoracolumbar fractures. Methods Fifty patients with thoracolumbar fracture treated in Xingning People’s Hospital from May 2017 to May 2018 were selected. Random number method was used to divide them into control group and observation group, with 25 cases in each group.The patients in the control group underwent conventional trans-traumatic posterior reduction and internal fixation. The patients in the observation group underwent pedicle screw internal fixation vertebra grafting. The total effective rate of the two groups were compared, and the prognosis of operation and the level of vertebral body indexes before and after operation and at the last follow-up were compared between the two groups. Results The total effective rate in the treatment group (96.00%)was higher than that in the control group (76.00%, P<0.05). The operation time, intraoperative bleeding volume, drainage volume after internal fixation, hospitalization time, Cobb angle and spinal canal encroachment rate after operation and the last follow-up in the observation group were significantly lower than those in the control group (P all<0.05), and the compression ratio of anterior vertebral body was higher than that in the control group (P<0.05). Conclusions Pedicle screw fixation vertebra bone grafting has significant surgical effect on thoracolumbar fractures, which can significantly strengthen the fracture site, and significantly improve the patient’s surgical conditions and accelerate postoperative recovery, so it is worthy of promotion. Key words: Vertebral screw internal fixation vertebra bone grafting; Thoracolumbar fracture; Cobb angle; Anterior high compression ratio; Spinal canal encroachment rate
