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 by percutaneuos fixationThose effects of the surgical methodology were analysied after surgery. The percutaneous pedicle system displays radiological, clinical, out comes superior to the distributed outcomes with conversative medication., Yet predominant with respect to blood loss, postoperative rehabilitation, more rapid return of the activities for day living. The outcomes of this technique demonstrate that this may be An valid, safe, technique for (A3) thoracolumbar burst fractures without neurological deficits.
