In the last decades, there has been an increasing use of instruments with pedicular screws for treating thoracic-lumbar spine fractures. This kind of fixation has the advantage of stabilizing the Denis’ three columns, as opposite to other instruments previously used, but it presents as a possible and feared complication the potential of vertebral channel penetration, pedicular fractures, involvement of nervous roots and vascular injuries. Our study aims to evaluate if computed tomography is a good analysis method for pedicular screws positioning and the potential complications of surgically passing them. Nineteen patients have been studied, totaling 134 screws, during the period ranging from November 2002 to February 2005, regarding X-ray, tomography and pre- and postoperative neurological function analyses. As a result, there were two cases of injury on pedicle’s lateral wall at the tomography image, with no clinical repercussion to patients. Regarding neurological deficit, no patient showed a worse condition. Six patients presented with an improved neurological status. We concluded that computed tomography is an excellent imaging test for evaluating pedicular screws, and this kind of fixation was safe and showed low morbidity rates, allowing an early mobilization of the patient.
