Abstract
In this paper a system for the virtual planning of hip operations with endoprosthetic
reconstruction and its application in bone tumor surgery is described. The system
enables the simulation of the operation and the construction of a custom-made implant
depending on the chosen resection planes and the patient’s anatomy. During the planning
process integrated virtual reality techniques facilitate the interaction with the
three-dimensional (3D) medical objects. Stereo viewing improves the perception of
the 3D nature of bone structures and tumors. In comparison to conventional planning
procedures, different operation strategies and their influence on the geometry of
the custom-made endoprosthesis can be easily compared. Furthermore, the combination
of multi-modal image information (CT and MR) enables an accurate 3D visualization
of the bone tumor within the bone.
