Expandable endoprosthesis for growing patients—Reliability and research

Nowadays expandable endoprosthesis for growing children is an alternative to amputation in the course of surgical treatment. Modern non-invasive endoprosthesis gives the possibility of elongation without a surgical operation. In the paper, the results of research with the application of computer technique in geometrical modelling are presented, as well as the design and manufacture in processing the medical images and experimental studies during an initial estimation of a new expandable prosthesis construction for growing patients, which will lead to the preparation for production and implantation processes in Poland.
