STRESS ANALYSIS OF THE TOTAL REPLACEMENT OF THE TRAPEZIOMETACARPAL JOINT

Abstract eng:
The article devotes to finite element analysis of the total replacement of the trapeziometacarpal (TMC) joint. Various types of analyzes were carried out dealing with influence of different geometry of the replacement. Apart from detailed models, more complex one including bones and ligaments was created to achieve more realistic conditions and thus, more trustworthy results. The goal of this study is to bring awareness about stress states depending on geometry of the replacement as well as provide an image of contact pressure distribution when loading the replacement.
