Burst fractures are relatively common injuries in the thoracolumbar spine. However, treatment of AO type (A3) unstable thoracolumbar fractures is still controversial, especially for patients with no neurological deficits. to evaluate the efficacy and safety of percutaneous pedicle fixation using a minimally invasive technique for AO type (A.3) thoracolumbar fractures. This study was done on ten patients complaining of thoracolumbar spine fractures grade A3 at ages ranged from twenty to sixtyfive years old. Those patients were treated bypercutaneuos fixation. The results of the surgical procedure were collected immediately after surgery, and then during, and after the follow up period. All the results was statistically analyzed to get positive data and correlation between them, complications was discussed whether after surgery or at the follow up period. The percutaneous pedicle fixation technique presents radiological, clinical, and functional results that are significantly better than the published results with conservative treatment. This intervention, assisted by fluoroscopy, proved to be a technique with a high accuracy and reliability, with results similar to those reported in studies with the classical transpedicular fixation regarding the deformity correction, but superior with regard to blood loss, postoperative rehabilitation, and return to the activities of daily living. The results of this study show that this is a valid, safe, and effective treatment for (A3) thoracolumbar burst fractures without neurological deficits.
