They have proved to be of major significance in surgical planning. Computer Aided Design (CAD) methods based on tomography are in the research phase for the three-dimensional reconstruction and display using computer graphics for even better visualization. We provide a method beyond that by manufacturing physical three-dimensional models via the Graphical Kernel System (GKS) and Computer Aided Manufacturing (CAM) methods. This kind of method is very well suited for visualization in some application areas. Moreover it yields physical models which can be manipulated in the preoperative phase. Lastly a physical bone model can be a substitute for the original object.10.1111/j.1467-8659.1985.tb00243.x375-382
