طراحی پروتز مفصل ران: تجزیه و تحلیل بازار، افقهای جدید و راه حل های نوآورانه

Within this approach, the present paper shows the results of a market analysis focused on hip prosthesis improvement. Therefore, using questionnaires sent to specialized physicians and medical centers, it was possible to collect information about pro and cons of existing devices identifying their criticalness’ with particular attention to stem osteointegration. In fact, compiling a QFD table, it was possible to design new concepts of the prosthesis stem which are here described and their mechanical resistance was tested using FEM simulations.
