Background  To compare the clinical efficacy of single posterior debridement, bone grafting and instrumentation with that of single-stage anterior debridement, bone grafting and posterior instrumentation for treatment of adult patients with thoracic and thoracolumbar spinal tuberculosis (TB).    Methods  We performed a retrospective analysis of 64 adult patients with thoracic and thoracolumbar spinal TB who underwent surgery between January 2011 and December 2014. Of the 64 patients, 34 patients were treated using a single posterior-only approach (posterior debridement, bone grafting and instrumentation; Group A). Thirty patients were treated with a combined anterior and posterior approach (single-stage anterior debridement, bone grafting and posterior instrumentation; Group B). Clinical manifestations, laboratory and imaging results were subjected to statistical analysis.    Results  The mean (±standard deviation) duration of follow-up was 16.8 ± 1.4 months (range, 10–34). Bony fusion was achieved in all the bone grafts with no loosening or breakage of internal fixation. In both of the groups, the visual analog scale (VAS) pain score, ESR and CRP at 6 weeks after operation and at the most recent follow-up were significantly lower than the preoperative level ( p  < 0.05). The operation time, intraoperative blood loss and length of hospital stay in group A were significantly less than those in group B ( P  < 0.05). As of most recent follow-up, no significant between-group difference was observed with respect to the American Spinal Injury Association classification status ( p  > 0.05). Furthermore, no significant between-group difference was observed with respect to preoperative kyphosis angle, and postoperative angle correction and angle correction rate ( P  > 0.05). One patient in group A relapsed 20 months after operation, and was successfully treated with debridement using the combined anterior and posterior approach.    Conclusion  Single posterior debridement, bone grafting and instrumentation for treatment of thoracic and thoracolumbar spinal TB can achieve similar curative effect as that with single-stage anterior debridement, bone grafting and posterior instrumentation, and is associated with additional advantages of shorter operation time, less bleeding and shorter length of hospital stay.
