[Case-control study on cortical bone trajectory screw and pedicle screw internal fixation for the treatment of senile patients with lumbar tuberculosis].

OBJECTIVE: To compare clinical effect of cortical bone trajectory (CBT) screw and pedicle screw (PS) internal fixation in treating senile patients with lumbar tuberculosis. METHODS: , PS internal fixation and anterior debridement, interbody fusion with bone grafting were performed. Length of posterior incision, intraoperative bleeding volume, operation time, time of bone graft fusion and complications between two groups were compared. Level of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), segment kyphotic Cobb angle before and after operation were compared, VAS score was used to evaluate pain releasing, JOA score was applied to evaluate clinical effect. RESULTS: <0.05). CONCLUSION: Both of CBT screw internal fixation and PS screw internal fixation could achieve satisfying results for the treatment of elderly patients with lumbar tuberculosis. PSinternal fixation has a long fixation but great trauma. However, CBT screw internal fixation only needs to fix adjacent segments of the lesion to reduce the fixation range, which has advantages of less trauma and strong screw holding force.
