Design and Structural Analysis of a Prothesis for an Arthroplasty. Definition of the Osseointegration Grade During the Rehabilitation Process
2019
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, a structural analysis of the set is necessary with the aim of defining the osseointegration grade in the different regions, considering the influence of the stress level which will be applied during the rehabilitation process, thus preventing bio-integration problems. The present communication aims to obtain the geometric model of a set by using CAD technologies and its posterior structural analysis by means of finite element analysis under the action of various load conditions. The prosthesis-humerus generated model becomes very useful for the orthopedic physician because it allows defining and programming the different stresses to apply during the rehabilitation process according to the osseointegration grade existing in the set region, thus preventing and minimizing the possible complications that could be derived by such process.
