DISEÑO Y ANÁLISIS ESTRUCTURAL DE UNA PRÓTESIS PARA UNA ARTROPLASTIA. DEFINICIÓN DEL GRADO DE OSTEOINTEGRACIÓN DURANTE EL PROCESO DE REHABILITACIÓN

Abstract

One of the main issues that shoulder arthroplasty presents during the execution of rehabilitation exercises is its mechanical stability. In the particular case of the prosthesis-humerus set, it is necessary a real structural analysis of the set with the aim of defining the osteointegration grade in the different regions and considering the influence of the level of efforts to apply during the rehabilitation process, thus preventing bio-integration problems. The present communication proposes to obtain the geometric model of a prosthesis-humerus set by using CAD technologies and its posterior structural analysis by means of finite elements under the action of various load conditions. The generated model becomes very useful for the orthopedic physician due to it permits to define and program the different efforts to apply during the rehabilitation process in function of the osteointegration grade existing in the set regions, and in this way to prevent and minimize the possible complications that could be derived by such process.
