The adolescent idiopathic scoliosis is a diagnosed disease in the beginning of puberty, with unknown etiology, characterized by lateral deviation of the spine (above 10°), which is related to vertebral rotation. The form of surgical treatment by spinal fixation with pedicle screws showed better results when compared to other fastening systems, but there are still technical difficulties at the time of passage and the choice of pedicle screws because of vertebral pedicles angle and diameter. Despite its advantages, this technique presents risks and complications, requiring a greater learning curve for the surgeon, as well as an adequate preoperative planning. So far, there is no literature report about the use of computed tomography as an aid to surgical planning of patients with scoliosis. In this light, the present study aims to describe a preoperative planning technique with the aid of computed tomography for spinal fixation in patients with Adolescent Idiopathic Scoliosis, specifying the angle and diameter of the vertebral pedicles, which may help the surgeon in the fixation.
