Objective To investigate the reasons for failure to treat thoracolumbar tuberculosis by anterior internal fixation and its countermeasures. Methods A total of 485 patients with thoracolumbar spinal tuberculosis underwent anterior focus clearance and fixation from January 2005 to January 2012. Eighteen of them failed with a rate of 3.71%. Screws were pulled out in two patients. Vertebra cutted by screws occurred in three patients. In another three patients, screws dropped into the intervertebral disc. Tuberculosis relapsed in 10 patients (5 accompanied with spinal deformity, 2 with pure malunion, 2 with abscess formation, and 1 with sequestra). Twelve of the patients underwent two-stage posterior pedicle screw internal fixation and anterior focus clearance and autogenous bone grafts fusion. Four were treated by shifting antituberculosis drugs and staying in bed. Two were cured by multiple abscesses puncture and antituberculosis injection. Results These patients were followed up for 15~30 months. Twelve cases of spinal tuberculosis were completely cured and 6 cases of them got clinical cure. However, 3 cases of them had scoliosis deformity followed and 1 had kyphosis. No tuberculosis relapse, cold abscess or sinus formation, or pedicle screw internal fixation failure occurred again. Conclusion Although there are many complications of anterior internal fixation for spinal tuberculosis, anterior internal fixation is still a perfect choice if we can make an appropriate choice of operation and strengthen the management after operation.
