In order to address problems yet unsolved in this respect, as well as the current needs of the national healthcare system, an interdisciplinary study was undertaken in the Biomedical Engineering Centre of the Silesian University of Technology, within the scheme of implementing a long-term research project entitled “A New Method of Surgical Treatment of Deformations of the Anterior Thoracic Wall”. The scientific purpose of the project was to develop a new type series of stabilisers intended for the surgical treatment of the funnel and pigeon chest. The study analysed biomechanical characteristics of the type series of individual elements of stabilisers pertaining to the state of displacement, deformation, and tension with the application of numerical and experimental methods, with the simultaneous identification of the optimal metal biomaterial. The analyses adhered to the clinical recommendations associated with the implantation technique. The previous surgical experiences had pointed to the need to reduce the rigidity of the system: stabilising plate – chest. Modification of the surface layer of the implants was also considered so as to enhance its corrosion resistance and biocompatibility, focusing also on the optimal sterilisation method in conditions adequate to the sterilisation used clinically.
