ON MODELING OF TUBULAR BONE CROSS-SECTION FOR DESIGNING ENDOPROSTHESIS STEM
АнотаціяModeling of cross-section contour of bone marrow channel is considered. Different methods of spline approximation are studied in common case. An approach for modeling of cross-section with characteristic form on the base of two curves combining is suggested in particular case. A method for contour description with varying one parameter of endoprosthesis stem is analyzed. Possibility of press-fit an endoprosthesis stem into marrow channel is examined. The principles of endoprothesis stem design on the base of 3D-model of bone marrow channel are proposed.
