PURPOSE: The study aimed to evaluate the efficiency of the posterior-only approach using shaped titanium mesh cage for surgical treatment of spinal tuberculosis (TB) in children. METHODS: Between January 2011 and July 2013, 22 children with a single motion spinal segment involved, including 10 with thoracic, 4 with thoracolumbar, and 8 with lumbar, were enrolled in the study. The patients were treated by the posterior-only approach using the shaped titanium mesh cages. Their medical records and radiographs were retrospectively analyzed. RESULTS: The mean operating time was 163 min (ranging from 120 min to 200 min). Blood loss was 210-550 ml with an average of 300 ml. The mean follow-up period was 41.1 months. At the final follow-up, all patients showed a solid bony fusion without the infection recurrence. The average bone fusion time was 6.2 months. The average correction of the local segment kyphosis angle was 6.9° (from 9.2° preoperative to 2.3° postoperative). Minimal loss in correction angle was noted in these patients at the final follow-up (only 1.5°). Changes in erythrocyte sedimentation rate, local segment kyphosis angle, and neurological status demonstrated a significant clinical improvement in all children at their last follow-up. CONCLUSION: Children with spinal TB of a single motion spinal segment involved can be successfully treated by the posterior-only approach using shaped titanium mesh cage. It is a minimally invasive, safe, and effective surgical procedure.
