CAD/CAM system for insole production

Impressive strides in medicine enhanced a necessity for advanced computer systems, providing measurement and visualization aids with high degree of accuracy and high standards for planning and application of specific medical procedures. Orthopaedy was enriched for a new approach in design and application of orthoses and prostheses, CAD/CAM. This paper gives an overview on biomechanical characteristics of the foot which directly implies the features of the future insole. Because of the unity of each foot the principle of universality i.e. mass production of insoles does not give the expected results. Therefore the advantage is given to production of insoles according to the clinical and pedobaroeraphic finding of the individual. The paper describes the developed CAD/CAM system enabling efficient interfacing of all phases in production of insoles. The system is developed by applying Open GL, Visual C++ and Visual Basic. It consist of the following modules: data base, module for processing and presentation of measured data, modules for presentation of picture files (BMP and RTG), module for modification and adjustments, and postprocessor.
