FRACAS: A System for Computer-Aided Image-Guided Bone Fracture Surgery
Femur fracture
Femur fracture fixation Closed interlocking intramedulary nailing
Problems with current procedure
Possible approaches
FRACAS: project goals
FRACAS concept Follow the bone fragment positions with 3D models on a computer screen instead of fluoroscopy
FRACAS system concept
FRACAS system components
Preoperative planning
Registration chain in FRACAS
Fluoroscopy-based registration
