Arrangement for producing an endoprosthesis anatomically made to measure

Abstract

Abstract An arrangement for preparing an anatomically measured endoprosthesis with a stem to be anchored in the widening end of a hollow bone, in particular a hip joint stem prosthesis to be anchored in the femur, uses radiographs true to scale, a set of a limited number of prosthesis templates and a set of corresponding prosthesis preparation models. In order to obtain greater variability and facilities for individual adaptation, a set of partial templates for that part of the prosthesis stem is provided which is to be anchored in the outer bone section forming the greatest widening. To determine the dimensions of the adjoining prosthesis stem sections, a direction scale and indicator are provided, the partial template and the a direction scale and indicator being mutually connected or connectable in defined directions. A set, corresponding to the partial templates, of trial preparation sections which are connectable to trial prosthesis sections; and for the adjoining prosthesis sections, is provided. Advantageously, the a direction indicator and scale are also each formed by one set of partial templates.
