Patient-specific templates (PST) is a novel method to guide the surgeons for allocating and detecting the positions and trajectories of pedicle screws in scoliosis surgery. Based on CT-scans and according to certain protocol, this technique will allow the surgeon to construct a 3D model of spine and present the stage and vertebrae which contain the most deformed bone. With preplanned surgery on specific software, we can develop an accurate and safe position of pedicle screws and its trajectories. This method has the ability to customize the placement and the size of each pedicle screw based on the unique morphology and landmarks of the vertebrae.
