Objective: The purpose of this study is to evaluate the clinical outcome of the two-stage operation for thoracic tuberculous spondylitis.
Methods: Eleven patients (4 male, 7 female) with thoracic tuberculous spondylitis were treated with two-stage operation. First stage consisted of anterior debridement and interbody fusion using rib graft and second with posterior instrumentation with fusion. Mean age was 46 years, and mean follow-up period was 18 months. All patients were treated with 12 months of antituberculotic medication postoperatively, and evaluated before and after surgery with respect to pain level, neurological status, associated lesions, hematological parameters and change of kyphotic angle.
Results: The associated lesions were pulmonary tuberculosis in 4 cases. There were no recurrences of infection and bone union was obtained within 6 months of the operation in all cases. Changes in the pain severity, neurological status, and hem-atological parameters demonstrated significant clinical improvement in all patients. The mean kyphotic angle was corrected from 17.8°to 9.8° after surgery. The most recent follow-up of the mean kyphotic angle was 12.3° with a loss of correction of 2.5° The preoperative VAS averaged to be 7.18 (range, 4-10). It decreased significantly an average of 1.45 (p<0.001).
Conclusion: These results indicate that two-stage surgical treatment for thoracic tuberculous spondylitis provid safe and satisfactory results. Spine instability and kyphosis can be also prevented by two-stage operation.
