Abstract

In the field of spinal surgery, it is common to use the pedicle screw fixation technique for thoracolumbar spine stabilization in a variety of procedures. In these procedures, the main complications are failure in fixation and poor screw positioning. Good preoperative planning is essential to reduce the risk of fixation failure and screw misplacement. Thus, this work presents SmartOrthos, a preoperative planning tool, which makes it possible to determine screw trajectories, evaluate the bone quality of these trajectories, through the biomechanical properties of the bone determined by means of computed tomography images. For validation, the presentation and application of the tool was carried out with two specialist surgeons, then a questionnaire was applied following the TAM methodology to collect the information. The results demonstrate that the tool can be used to support the planning of pedicle screw fixation and that it can also help to reduce the risk of complications.
