Background: The transition from the less mobile thoracic spine with its associated ribs and sternum to the more dynamic lumbar spine subjects the thoracolumbar region to significant biomechanical stress. Minimal invasive spine surgery developed from dissatisfaction of excessive exposure, postoperative pain or scarring. Thus, percutaneous surgery, by sparing the paravertebral musculature, should limit bleeding, reduce infection rates and postoperative pain, which would reduce the length of hospital admission, makes rehabilitation easier and faster and could limit the destabilization of adjacent levels over the long term. Method: although minimally invasive spinal surgery requires suitable instrumentation, we present the case when adjustment of surgical techniques, with delicacy and refinement, enabled the creation of a minimal invasive spinal surgery with classic instrumentation. We present our study of 19 patients with thoracolumbar fractures treated in our hospital in the last years and the follow-up results at 1 year. Results: Despite the fact that for percutaneous fixation we used classical surgical instruments, we obtained similar results with those obtained in international studies using, adequate’’ instruments for percutaneous pedicle screw fixation. In our study patients treated with percutaneous fixation had less operative time, blood loss, less postoperative pain (VaS and Denis Scale) less hospital stay and we didn’t have any infection-related complications. Conclusion: Despite that fact that we used,inappropriate’’ instruments for percutaneous minimally invasive posterior pedicle screw fixation we obtained similar results with other reported data. percutaneous surgery aims fewer soft tissue injuries and post-op results as good or better, compared with open, posterior approach.
