title: [Can samples from the cups of Weller endoprosthesis be the basis for analysis of the degree of biomaterial crystallinity under the influence of external factors?].
abstract: The paper is a thesis verification. The thesis stated that samples from cups of Weller endoprosthesis can be the basis of biomaterial crystallinity analysis under the influence of external factors. Cup segments were deformed and exposed to X-rays. Basing on thermoanalytic analysis the authors prove that the cups (completely transformed and sterilized) cannot be used as research material, to be tested by application of external factors, to assess polyurethane morphology. An alternative reliable method has been proposed: direct investigation of the material used for cup production. These conclusions were reached as result of research done with a differential scanning calorimeter (heat-flux type) DCS 30 in Mettler TA-4000 thermoanalytic system.
