Posterior fixation, anterior debridement and bone grafting in the treatment of thoracic and lumbar tuberculosis in children younger than 3years of age.

Abstract

This study aimed to investigate the clinical outcomes of posterior fixation, combined with one- or two-stage anterior debridement and bone grafting in treating children younger than 3years of age with thoracic and lumbar tuberculosis. This was a retrospective study involving 16 young children with thoracic or lumbar tuberculosis. Surgical data were recorded. Frankel Grade was used to assess neurological function. The regional kyphosis angle was measured to evaluate the deformity correction. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were detected to assess the activity of tuberculosis. Bony fusion and complications were also recorded. The mean operation time was 204.4 ± 41.8min. The mean estimated blood loss was 126.3 ± 94.4ml. Preoperative Frankel Grade results indicated five patients with Grade C, six with Grade D, and five with Grade E. At the final follow-up, all patients were in Grade E. Twelve patients were brought back to normal spinal alignment and the rest four patients remained kyphotic. There was an improvement of 29.3° ± 18.3° in regional kyphotic angle postoperatively. And the deformity correction was 27.4° ± 19.1° at the final follow-up. ESR and CRP decreased to a normal range at three months follow-up. Bony fusion was achieved in all patients. None of the cases developed fixation failure, pseudoarthrosis, or tuberculosis recurrence. Posterior fixation, combined with one- or two-stage anterior debridement and bone grafting, is a safe and effective surgical strategy for treating young children with thoracic and lumbar tuberculosis.
