Bones implants based on Fe and Mg
Košíček, Adam ; Zatloukal, Miroslav (referee) ; Sedlaříková, Marie (advisor)
This paper work deals with properties of metallic biomaterials in terms of their suitability for use as a temporary metal implants. The work focuses on biodegradable materials based on iron and suitable alloying elements, which would create a perfect implant. A part of this work describes procedure of creating biodegradable metallic samples with alloying element Magnesium and measuring the corrosion rates. There are a few theoretical chapters concerning permanent implants, function and composition of human bones, iron and magnesium in human body and biodegradable materials.

Middle ear implants in clinical practice
Ondrášková, Lucie ; Janoušek, Oto (referee) ; Provazník, Ivo (advisor)
The paper is a brief overview of anatomy of the ear, hearing screening, diseases and disorders affecting the organ of hearing. Next, there are listed the first ideas implants and their materials and there are described middle ear implants used nowadays and the latest surgical procedures, relevant legislation and the reaction of the body on the implant. The practical part will consist of collecting clinical data comprise the number and types of operations, air and speech audiometry and subsequent statistical evaluation. At the conclusion will be discussed and reviewed the statistics.

Stress-strain Analysis of Chosen Spinal Fixation Device
Prášilová, Eva ; Valášek, Jiří (referee) ; Marcián, Petr (advisor)
The degenerative and traumatic injuries of a spine are very frequent. In those cases it is necessary to stabilize the corresponding spine segment using a spine implant. The spinal implants are rigid or flexible, the latter known as dynamic ones in medical practice. In this thesis, the problems of the physiological spinal segment and the segment with implant were solved using the computational modelling (finite element method). Computational model consists of 4 lumbar vertebrae L2 – L5, intervertebral discs, joints and spinal implants. The spinal segment was loaded by the force 400N and 200N, than by force 200N together with bending moments 2,5Nm and 5Nm depending of the motion. The displacement of the whole system, contact pressure of cartilages, equivalent strain in cancellous bone and equivalent stress in the implant were analyzed. The deformation of the physiological model and the model with the implant are comparable, but the bone tissue of the model with the implant is dramatically more loaded in vicinity of the screws.

Biocompatible titanium alloys and theirs application
Hofírek, Michal ; Kohout, Jan (referee) ; Věchet, Stanislav (advisor)
This thesis presents use of titanium alloys in medical applications in form of literature research. In first part the basic properties of titanium as element are discussed as well as its behavior in alloys. Next part focuses on proper explanation of term biocompatibility and sums up specific requirements for alloys used in orthopaedic applications. These properties are shown on alloy Ti-6Al-4V ELI and other selected titanium based alloys which are currently being developed.

Modern methods of implant manufacturing by Rapid Prototyping technology
Trubačová, Pavlína ; Sedlák, Josef (referee) ; Píška, Miroslav (advisor)
This research describes the possibilities of using unconventional technologies known as Rapid Prototyping methods. These methods make part of Additive manufacturing technologies. The project investigates the influences of process parameters on the final part quality and analyses the advantages and the disadvantages of using RP technologies for medical application, mainly for implant fabrication. The objective of experimental part is fabrication of samples by Selective Laser Melting (RP technology). The stainless steel will be used and two parameters will be varied (laser power, component inclination). For final evaluation of mechanical properties, surface quality, Alicona machine, compression test and Vickers’ hardness test will be used.

Patient after total joint replacement Preoperative and postoperative education
CHMELAŘOVÁ, Zdeňka
This bachelor thesis deals with the patients? education in the pre- and post-operative period after their joint replacement. Currently, the number of total endoprosthesis (TEP) operations has increased rapidly. Also in this case the role of a nurse as an educator is uninterchangeable and without her it is difficult to imagine such a demanding operation. It is the nurse herself or himself who draws patient?s attention towards all the aspects concerning pre-hospitalization period, hospital treatment and private care after the patient has been released home. It is the nurse who has to establish a relation of trust between a patient and hospital staff. The aim of this thesis was to elaborate methodically the TEP patient?s education possibilities in the pre- and post-operative period and to judge its quality from the TEP patient?s point of view. By means of an experimental survey and by fulfilling its aim it has been found out that the TEP patient?s education in medical institutions takes place, nevertheless, it is not on a sufficiently high level.
