Posterolateral decompression, bone graft fusion, posterior instrumentation, and local continuous chemotherapy in the surgical treatment of thoracic spinal tuberculosis

To investigate the clinical efficacy of surgical treatment for thoracic spinal tuberculosis with kyphosis deformity via posterolateral debridement, fusion, posterior instrumentation and local continuous chemotherapy. A total of 25 patients with thoracic tuberculosis received surgery by posterolateral decompression, fusion, posterior instrumentation, and postural drainage with local continuous chemotherapy between June 2009 and October 2011. The clinical outcomes was evaluated using statistical analysis about deformity correction, bone fusion, neurologic status, and the visual analog score (VAS) and erythrocyte sedimentation rate (ESR). All of 25 patients were followed up for 39.0 ± 10.7 months (range, 24–60 months) postoperatively. There was no recurrence of tuberculosis, breakage and looseness of internal fixation. Bony fusion was achieved in all cases with 6.7 ± 1.9 months. The values of ESR recovered to normal within 6 months postoperatively. All patients with neurological deficit had significant improvement at the final follow-up. The average preoperative Cobb angles were significantly decreased to 12.2 ± 2.9° (range, 8–17°) postoperatively, and at final follow-up were 12.9 ± 2.7°. Our results showed that single-stage posterolateral debridement fusion, posterior instrumentation and local continuous chemotherapy can be expected to yield satisfactory clinical and radiographic outcomes in patients with thoracic spinal tuberculosis.
