ABSTRACT:
The present invention relates to methods of preparing a model of a bone endoprosthesis, and is most effectively used for the preparation of models of proximal femur in artificial hip joints.
The method of preparing said model consists in that a bone procured from a cadaver and corresponding to the bone to be subsequently replaced by a prosthesis is divided into two equal parts, the spongy tissue thereof is removed, thus forming a groove-like excavation in each part, thereafter the two parts are brought together in a fashion that the two grooves form a cavity serving as a casting mold wherein ventilation and filling orifices are made, wherethrough a self-hardening filling compound is poured, after which said mold is disassembled, and the model removed.
