Anterior debridement and bone grafting of spinal tuberculosis with one-stage instrumentation anteriorly or posteriorly

Between 2000 and 2004, 40 cases (average age 38, range 16-65 years) of spinal tuberculosis were treated with anterior debridement and iliac bone graft with one-stage anterior or posterior instrumentation in our unit. All patients received at least 2 weeks of regular antituberculous chemotherapy before surgery. We followed up all patients for 12-48 months (mean 22 months). Local symptoms of all patients were relieved significantly 1-3 weeks postoperatively; 23 of 25 cases (92%) with neurogical deficit had excellent or good clinical results. Erythrocyte sedimentation rates (ESR) returned from 51 mm/h to 32 mm/h (average) two weeks postoperatively. Kyphosis degrees were corrected by a mean of 16 degrees. Fusion rate of the grafting bone was 72.5% one year postoperatively and 90% two years postoperatively. Severe complications did not occur. We therefore believe that patients undergoing anterior debridement and iliac bone grafting with one-stage anterior or posterior instrumentation achieve satisfactory clinical and radiographic outcomes.
