The first part of this paper deals with consequences and treatment of trapeziometacarpal joint disease called rhizarthrosis. Rhizarthrosis consists of some different phases. Initial phase can be asymptomatic, but in next phases bad mobility and unpleasant pain can occur. There are many ways how to reduce the pain and improve the mobility caused by rhizarthrosis. However, in serious cases the problem can be solved completely only by the total joint replacement. There have been many surgeries carried out since 2008 in the Czech Republic. Development of such total joint replacement is still current thanks to its optimization. There are some advantages resulting from the development, e.g. longer lifespan of the implant, better biocompatibility etc. Therefore the second part of the paper aims at stress and deformation analysis of simplified model of the joint replacement. An equivalent stress and a contact pressure are investigated.
