Assessment of the Feasibility of Using a Preoperative Surgical Fracture Analysis Tool

Based on a pre-operative computed tomography (CT) scan, fractured bone fragments of a proximal tibia are segmented and aligned to achieve adequate fracture reduction. Bone material properties for each fragment are derived from Hounsfield Units (HU) of the CT scan, based on internal density calibration with air, fat, muscle, and cortical bone. Screws and implants are then modelled based on the manufacturer's design and material properties Placement of off-the-shelf plate and screws can be analyzed and support a personalized plan on how to individually treat a patient with a specific fracture pattern and anatomical biometric data. Surgeons can define up to three approaches (different placement of implants and screws) to be visualized and analyzed for construct stability. The surgeons will receive a visualization of the fracture, fracture-reduction, implant and screw placement in 3D as well as a comparison of construct stabilites of the submitted approaches
