One-stage anterior focus debridement, interbody bone graft, and anterior instrumentation and fusion in the treatment of short segment TB

Abstract

To evaluate the clinical efficacy of 1-stage anterior focus debridement, interbody bone graft, and anterior instrumentation and fusion in the treatment of short segment thoracic tuberculosis with paraplegia or incomplete paralysis. A total of 16 adult patients with short segment thoracic spinal thoracic tuberculosis who underwent surgery were enrolled in this retrospective study. All patients received anterior focus debridement, interbody bone graft and anterior instrumentation and fusion. All patients were followed up for 24 to 48 months. Clinical manifestations, laboratory examinations, neurological symptoms, bone fusion and imaging results were analyzed. All patients successfully underwent operations. The symptoms of chest and back pain were alleviated and even disappeared during postoperative 1 to 6 months. There was no recurrence. All patients got bony spinal fusion within postoperative 4 to 8 months assessed by spinal X-ray film. The levels of erythrocyte sedimentation rate and C-reactive protein were significantly decreased from 72.6 ± 27.5 mm/h and 75.7 ± 25.9 mg/L to 15.9 ± 4.6mm/h and 4.7 ± 2.0mg/L at the final follow-up, respectively (P < .05). The thoracic kyphosis angle was also notably decreased from 15.0 ± 3.4° to 9.1 ± 1.9° after operation(P < .05). During the follow-up, the symptom of paraplegia or incomplete paralysis was significantly improved. Neurologic status in all patients was also improved to some extent. The combination of 1-stage anterior focus debridement, interbody bone graft and anterior instrumentation and fusion is an effective and feasible treatment method for short segmental thoracic tuberculosis with paraplegia or incomplete paralysis.
