One stage posterior debridement, non-structural bone graft in the surgical treatment of single segment thoracic tuberculosis: A retrospective single-center cohort study

Objective To compare the clinical efficacy of non-structural with structural bone graft in the surgical treatment of single segment thoracic tuberculosis after one stage posterior debridement. Methods 61 patients with single segment thoracic tuberculosis treated by one stage posterior debridement, bone graft fusion and internal fixation were retrospectively analyzed. Among them, 35 cases were admitted from 2015 to 2017 in the non-structural bone graft group and 26 cases were admitted from 2011 to 2015 in the structural bone graft group. The visual analogue scale (VAS), erythrocyte sedimentation rate (ESR), C reactive protein (CRP), neurological function, operation time, operative blood loss, hospital stay, correction and loss of Cobb angle, bone graft fusion time and complications were recorded and analyzed. Results Compared with structural bone graft group, the operation time of non-structural bone graft group was shorter and the operative blood loss was less, but the hospital stay was longer (P Conclusion Non-structural bone graft has less surgical trauma and shorter bone fusion time compared with structural bone graft in the surgical treatment of single segment thoracic tuberculosis. The two methods may achieve comparable clinical efficacy in alleviating symptoms, correcting kyphosis and improving neurological function for appropriate cases.
