Efficacy of One-Stage Posterior Debridement and Bone Grafting with Internal Fixation in the Treatment of Monosegmental Thoracolumbar Tuberculosis

•The first study of one-stage posterior debridement and bone grafting with internal fixation for monosegmental thoracolumbar TB.•The data from 88 patients with thoracolumbar TB were retrospectively analyzed.•Significant differences were found between preoperative and final postoperative values.•The parameters measured included Cobb angle, neurologic deficits, ESR and CRP levels, VAS score.•One-stage posterior debridement, bone grafting, and internal fixation might be better for monosegment thoracolumbar TB.
