Abstract
Objective To evaluate the clinical efficacy of the posterior pedicle screw short-segment internal fixation for type AO-B1 thoracolumbar vertebrae fracture-dislocations. Methods 12 cases of the type AO-B1 fracture-dislo-cations of thoracic and thoracolumbar vertebrae with spinal cord injury were analyzed retrospectively. One-stage all patients were treated with redution, strut bone grafting, two-segment pedicle screw rod fixation through the fractured-dislocated vertebrae. The interval of the dislocated vertebrae, the height recovery of the fractured vertebrare body, and the deformity correction of the fracture-dislocations were evaluated by X-rays, and neurologic status were evalua-ted by Frankel classification before and after operation and at final follow-up. Results 12 patients were followed up for 12~36 (23 ± 5) months. Postoperative Frankel′s functional classification:Grade A was improved to C in 1 case, Grade A to D in 1,the lesions remained unchanged in 7;Grade C to E in 2 and Grade D to E in 1. Radiographic ima-ging displayed internal fixation in the correct position. The dislocation in sagittal plane in all of 12 patients had been completely corrected,the rate of deformity correction was 100%. The height of the fractured vertebrae and interval of the dislocated vertebrae had been recovered. No sign of breakage of pedicle screw and connection rod had been seen. There was no obvious evidence of correction loss at final follow-up. There were 3 cases of apparent adjacent segment degeneration. Conclusions It is an effective method to treat type AO-B1 thoracolumbar vertebrae fracture-disloca-tions with two-segment pedicle screw fixation through the fractured vertebrae. It is very necessary for CT examination preoperative in the diagnosis and treatment.关键词
