Biodegradable bones implants based on iron
Hrabovský, Jan ; Zatloukal, Miroslav (referee) ; Sedlaříková, Marie (advisor)
This work deals with a current topic, which are biodegradable bone implants. These implants seem to be a suitable candidate for temporary fixations, with their gradual decomposition. An important parameter is not only the mechanical properties so that the material can withstand the load, but above all the corrosion properties and the degradation process. This work introduces the physiology of bone, trace elements and also describes current trends in the field of implants. The last part is a theoretical introduction to cross-stage processes. The practical part is focused on the preparation of iron-based samples with various dopants, subsequent annealing and analysis.

Trends and forecasts in the technology of artificial disc replacement
Bodlák, Daniel ; Jelen, Karel (advisor) ; Říha, Michal (referee) ; Jíra, Aleš (referee)
1/1 škola: UNIVERZITA KARLOVA V PRAZE, Fakulta tělesné výchovy a sportu disertační práce: "Trends and forecasts in the technology of artificial disc replacement" autor: Ing. Daniel Bodlák datum: prosinec 2023 Abstract: The aim of the work was the study of current and new directions and trends in intervertebral disc replacement technology, a critical evaluation of current methods using implants for the treatment of degenerative disc disease, as well as a forecast of further development. The work also contains the related results of the collaboration on the optimization of the total "ball and socket" lumbar disc replacement within the project TA01010860 "Solving the problem of intervertebral disc replacement using modern knowledge, engineering methods and progressive technologies". In the part of the dissertation, focused on theoretical starting points, the attention is paid first to the intervertebral disc itself and its various aspects, from anatomy, through biomechanics and degenerative diseases, to the issue of implants for its partial or even total replacement. Subsequently, current trends and progressive methods of treatment are processed. The results section begins with a description of the methods used and then presents the results themselves, both from literature research and experimental work....

Biodegradable Mg-based materials for stents and bone implants
Zemková, Mária ; Král, Robert (advisor) ; Stráská, Jitka (referee)
The bachelor thesis is focused on the effect of mechanical processing rotary swaging (RS), specifically on the microstructure, mechanical properties and corrosion properties. The investigation was performed on the magnesium alloy AE42 with a different number of RS passes, which can be useful for medical applications. RS is more efficient and cheaper alternative to different material processing methods producing fine-grained struc- ture. Fine-grain structure with grain boundaries with high angle misorientation was achieved by this process. Microstructure was inhomogeneous - the grain size decreased from the surface to the center. An improvement of mechanical properties with the increase in the number of swaging steps was observed. Processing also led to a decrease in corrosion resistance in this alloy. Microstructure development was investigated by electron microscopy scanning. Development of mechanical properties was characterized by compression deformation tests and microhardness measurements. Linear pola- rization method was used for the interpretation of corrosion resistance. 1

Biodegradable bones implants based on Fe
Tkáčová, Tereza ; Míka, Martin (referee) ; Sedlaříková, Marie (advisor)
This thesis writes about biodegradable bone implants based on iron. The currently used metal-based implants have disadvantage in an often need of secondary surgery intervention to remove the implant. Therefore, there is a big research of biodegradable bone implants nowadays. In this work, iron-based materials with the addition of zinc and magnesium are being investigated. The produced samples have been immersed in a solution of NaCl and simulated body fluid, SBL. Subsequently there were regularly analysed changes of corrosion potential, pH, conductivity and also weight loss was watched.
