Efficacy of surgery via the single anterior and single posterior approaches for treatment of thoracic spinal tuberculosis

Objective The type of surgical treatment that should be adopted for thoracic tuberculosis (TB) remains controversial. This study was performed to compare the clinical efficacy of surgery via the single anterior and single posterior approaches for treatment of thoracic spinal TB. Methods Seventy-eight patients with thoracic TB undergoing surgical treatment were divided into two groups on the basis of the surgical methods employed: Group A (single anterior debridement + bone graft fusion and internal fixation) and Group B (single posterior debridement + bone graft fusion and internal fixation). Results of clinical and imaging examinations were analysed and compared between the two groups. Results The surgical duration and mean hospital stay were significantly longer and the perioperative bleeding volume was significantly higher in Group A than B. At the last follow-up, changes in the American Spinal Injury Association grade showed no obvious differences between the two groups. Before and after the surgery and at the last follow-up, no significant differences were detected in the Cobb angle change or correction rate between the two groups. Conclusion Surgery via the single anterior and single posterior approaches achieved good clinical efficacy in the treatment of thoracic spinal TB.
