High energy impacts at joint locations often generate highly fragmented, or comminuted, bone fractures. A leading current approach for treatment requires physicians qualitatively to classify the fracture to one of four possible fracture severity cases. It has been observed that qualitative evaluation of fracture severity by physicians can vary significantly which can lead to potential misclassification and mistreatment of these fracture cases. The system described in this book applies novel three-dimensional (3D) puzzle-solving algorithms to identify the fracture fragments in the CT image...
