Comparison of hemispheric and conical cup in the total trapeziometacarpal joint replacement
 Kukučka, Ivan ; Švancara, Pavel (referee) ; Fuis, Vladimír (advisor)
This diploma thesis deals with the comparison of total replacement of a trapeziometacarpal joint with a hemispherical cup and replacement of the same joint with a conical cup. In both cases of implants, these are types of replacements with dual mobility. The focus of the diploma thesis is the comparison of the transfer of forces from the head of the prosthesis to the trapezius bone through the different shape of the cup. The work was processed using computer software ANSYS Workbench 19.3.

Comparison of force transmission between trapezio-metacarpal prosthesis with dual mobility and standard prosthesis with fixed polyethylene in cup
 Lamrich, Richard ; Švancara, Pavel (referee) ; Fuis, Vladimír (advisor)
Presented master thesis focuses on comparison of total replacement with fixed polyethylene and replacement with dual mobility of trapeziometacarpal joint. Computational models consist of bones trapezium, trapezoid, first and second metacarpal and components of total replacements stem, neck, insert and cup. Replacements are compared on basis that how big force is transmitted from replacement to trapezium, contact pressures between neck and insert, equivalent elastic strains of bone tissue and lastly what is the influence of friction coefficient on results. Task was solved with finite element method in software ANSYS Workbench 19.2.

Stress and deformation analysis of the stem and cup of the total replacement of the trapeziometacarpal joint
 Svojanovský, Tomáš ; Vosynek, Petr (referee) ; Fuis, Vladimír (advisor)
The center of attention of this bachelor’s thesis is stress and deformation analysis of the total replacement of the trapeziometacarpal joint. The first part is formed by medical essence of the matter, namely from the anatomical and pathological point of view. The connecting link between literature research and analysis creates a short introduce to the finite element method. To the stress and deformation analysis itself was used the program ANSYS Workbench 14.5 based just on the finite element method. One of the purposes is to get to know this program and to learn to gain correct results. The main target is to catch and describe stress and deformation of the simplified model of a certain implant. Despite some of the simplifications, resulting values should approach to the real values. Except for the mentioned analysis, there are introduced different approaches, which could be used for the solution. There is also some comparison of advantages and disadvantages of particular approaches.
