The medical three-dimensional model currently uses as an invaluable source of information to enhance clinicians in preoperative surgical planning. The favourable computer-aided design tool applied to improve the visualization quality of the medical model. In this study, the virtual reconstruction of proximal femur fractures with multi fragments was included. The mesh correction and smoothing algorithm also performed. The aim study is to analyze each step of the visualization digital model and their aspects that affect the accuracy and reproducibility. It found the complex fracture model took longer to reconstruct the virtual model. The beneficial approaches described in this study are not just limited to orthopaedic case, but also for many other fields of medicine.
