Abstract:
Objective To evaluate the clinical efficacy of AF (atlas fixator) internal fixation in treatment of thoracolumbar fracture and dislocation. Methods 42 cases of thoracolumbar fracture were treated by posterior AF internal fixation. Prior to surgery, anteroposterior and lateral radiographs, and CT scan through bone windows were done for all the patients. During surgery, all the pedicle screws were inserted by Mergerls method and proper insertion was confirmed by radiographs. Results The follow ups of 39 patients averaged 21 months (ranging from 6 to 29 months). After surgery, the correction of anterior vertebral body height averaged 40.2%, and of Cobbs angle 23.2?. 12 cases of incomplete spinal cord injury had significant improvement and 2 ones of complete spinal cord injury had no improvement. Conclusion The AF screw is especially helpful in reconstruction of stability of thoracolumbar region after posterior decompression and reduction, because it results in simplicity, safety, less fixation segments, and little invasion or bleeding.
