The stability of the spinal column is essential, since it serves as the primary structural support for the human body and protection for the spinal cord. Although pedicle screw fixation is currently the gold standard for treating spinal deformities, fractures, and instabilities, it is still a technically challenging procedure because of the close proximity to critical neurovascular structures. Advanced infrared navigation systems are frequently prohibitively expensive and ergonomically limited by the need to shift attention to remote external monitors, while traditional intraoperative guidance techniques, such as fluoroscopy, expose surgical teams to ionizing radiation and suffer from 2D-3D mismatch errors. To address these issues, this thesis proposes the development of an affordable Augmented Reality (AR) navigation system based on infrared light tracking, specifically designed as a simulation tool to train medical students in performing the pedicle screw fixation procedure safely.
