| 【Abstract】 Objective：To evaluate the feasibility and efficacy of the modified posterior debridement，compact bone graft and internal fixation for thoracolumbar tuberculosis.Method：From January 2005 to March 2010，17 patients with 2 consecutive segments tuberculosis in thoracolumbar spine were reviewed retrospectively.All cases underwent modified posterior debridement，compact bone graft and short-segment internal fixation.Among them，there were 4 T12-L1，7 L1-L2，and 6 L2-L3.Imaging examination revealed small amounts of paraspinal abscess.Cobb angles before surgery were 22°-50°（average，31.2°）.All cases presented with neurological deficit prior to surgery，based on ASIA scale，there were 9 grade C and 8 grade D.Antituberculosis chemotherapy and nutrition supplement were performed routinely before and after surgery.Result：All operations were performed successfully with no neurovascular or major organ injury noted.Operation time was 155.4±21.6min；the amount of blood loss was 511.8±98.2ml；and the amount of transfusion was 164.7±157.9ml.Days of hospitalization were 14.7±1.0d.2 cases were complicated with nerve irritation，which was resolved 1-2 weeks later；1 case developed sinus at skin incision，which was resolved with corresponding drainage.All patients were followed up for an average of 30 months（range，13-47 months）.The Cobb angle at after operation and final follow-up was 13.0°±5.6° and 14.8°±5.8° respectively，with the rate of correction and loss of correction of 58.3％ and 5.8％ respectively.All cases got solid bony fusion at 4-7 months postoperation.During follow-up，no instrument failure and recurrence of tuberculosis were noted.3 cases suffering from neurological deficit recovered to grade D，while the others with normal neurofunction recovered to grade E at final follow-up.Conclusion：Modified posterior debridement，compact bone graft and internal fixation is reliable for 2 consecutive thoracolumbar（T12-L3） tuberculosis. |
