Clinical outcomes of first metatarsophalangeal joint prosthesis PH-Flex Medin and its effect on the biomechanics of the forefoot in the propulsion phase of the gait cycle
Popelka, Stanislav ; Hromádka, Rastislav (advisor) ; Krbec, Martin (referee) ; Holinka, Martin (referee)
The dissertation evaluates the results of a first metatarsophalangeal (MTP) joint replacement. The PH-Flex MTP joint replacement was developed at the 1st Department of Orthopaedics, the first faculty of medicine in conjunction with the Medin s.r.o. company. The clinical trials ran between 2007 and 2011. Between 2011 and 2016, the implant was used in clinical practice, where the indication criteria of its use were gradually adjusted. This work summarises publications originating in our department, evaluating the 5-year period during which the implant was used and the results of its use. In the first part of the dissertation, we present the retrospective study evaluating a group of 31 patients after the implantation of 35 MTP joint replacements was published in 2017. Bilateral surgery was performed on 4 patients. A minimum follow-up of 6 months was required for inclusion in the study. In 30 cases, the indication was 1st MTP joint arthritis of grades 3 and 4 according to the Coughlin classification. A conversion from hemiarthroplasty to total arthroplasty was performed in 4 patients, and in 1 case, the surgery was performed as a revision from a failed silastic 1st MTP joint replacement. The evaluation was performed not only radiographically but also according to the American Orthopaedic Foot and Ankle...

Development of the first metatarsophalangeal joint replacement
Barták, Vladislav ; Popelka, Stanislav (advisor) ; Stehlík, Jiří (referee) ; Krbec, Martin (referee)
The work provides a comprehensive overview of the issues hallux rigidus with a focus on the first metatarsophalangeal joint replacement and development of our own implant. The development was built to perform anatomical studies, the results were the basis for the construction of hemiarthroplasty and total arthroplasty. It was necessary to measure the marrow cavities of the distal part of first metatarsal and proximal half of proximal phalanx. We measured the size of the metatarsal head in two planes, and its tendency to diaphysis on the dry preparations. Through these studies we obtained valid data for the construction all components of both hemiarthroplasty and total arthroplasty of specifying the size spectrum. We have verified and then corrected the shape of implant treatment during post-mortem tests on the models. The result is a new type of arthroplasty with their own design to guarantee restoration of joint function and coated with a high osteointegral potential. In clinical studies, we performed 22 implantations of hemiarthroplasty and one implantation of total arthroplasty. Clinical results suggest the fact that the implant will be successful. However the ultimate answer to this question will provide long-term study. The other results presented with a detailed anatomical description show to...

The effect of footwear on deformity of the foot in a woman - the role of the nurse in prevention
MLEJNKOVÁ, Natálie
The topic of this diploma thesis is "Influence of footwear on foot deformities in women - the role of nurses in prevention". The theoretical part is devoted to the foot anatomy, it describes the issue of heels on the foot and represents the Giraffe certification. The practical part of the qualitative research shows the role of nurses in preventing foot deformities for patients. This thesis has two goals. To find out what footwear affects the deformities of the legs in women and to find out what role the nurse plays in preventing this issue. The research questions are 1. What is the importance of wearing high-heeled shoes for women and how will this be reflected later? 2. What role do nurses attribute to the prevention in this issue? Data collection was collected by semi-structured interviews with nurses in the orthopaedic ward and orthopaedic clinics. The research sample consists of 20 respondents, the choice was deliberate and formed by snowball sampling. In February 2019, data was collected, which was subsequently terminated at the moment of theoretical saturation. The interview covered themes: wearing high-heeled shoes, leg deformities caused by high-heeled shoes, nurse-led prevention and education. The results show that only a fraction of nurses adhere to the role of a nurse who helps patients prevent leg deformities. The rest of the nurses leave prevention and education to doctors. This diploma thesis presents as a work output a poster, which can be an information material for nurses from the orthopaedic clinics and beds. The output of the thesis is an educational poster that will reflect the entire nursing issue in prevention (the role of a nurse, the deformity of the feet caused by high-heeled shoes, etc.).
