    Kommunikation mellan patient och ortopedingenjör: En kvalitativ studie2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    En studie har genomförts med syftet att undersöka diabetespatienters tolkning av informationen som ges av deras respektive ortopedingenjör under ett patientmöte samt undersöka vad ortopedingenjören anser sig ha förmedlat för information till patienten under patientmötet. Metoden i studien är kvalitativ där intervjuer med semistrukturerade öppna frågor har använts. I studien ingick två ortopedingenjörer samt två diabetespatienter. Efter avslutade intervjuer har materialet från intervjuerna analyserats och bildat kategorier. Dessa kategorier har sedan använts för att finna skillnader samt likheter mellan ortopedingenjörens och patientens tolkningar. Patientmötens har spelats in för att få möjligheten att se vart missförstånd uppstått. Genomgående i resultatet var att ortopedingenjören anser sig ha förmedlat mer information än vad patienten beskriver under intervjuerna. Några missförstånd upptäcktes men kommunikationen mellan parterna var god.

    Assessment of function of a 3D-printed body-powered upper limb prosthetic device2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose

    Conventional arm-prosthesis are expensive to make and therefore limit the availability for users on the geographical locations there the user pays for it. This study compares the hand function of a 3D-printed prosthesis with lower production cost with a traditional prosthesis.

    Method

    A test person performed two different tests of hand function (Box and Block test and Nine-hole peg test) with a myoelectric trans radial prosthetic arm and a body powered 3D printed trans radial prosthetic arm. The test person also answered two parts of the orthotics and prosthetics users’ survey (OPUS) considering both prosthetic arms.

    Result

    The 3D-printed prosthesis performed worse than the traditional prosthesis in the two tests of hand function and generally worse in the questionnaire about the function of the prosthesis. Though it got higher values in comfort and affordability.

    Conclusion

    There was a significant difference in function between the 3D-printed prosthesis and the myoelectric prosthesis but the printed prosthesis could perform many activities in daily living. Whether the 3D-printed prosthetic device is priceworthy or not is hard to measure because of different criteria, therefore a conclusion is hard to reach.

    Mechanical properties of trabecular structures produced by SLM, as a function of the trabecular morphology2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Eurocoating, Italy, is a company that works in the biomedical sector. They have for a long time created prostheses from CAD files achieved from customers, and now they want to build their own expertise about the design. The thesis work was a part of a three year long collaborative research project between Eurocoating and University of Trento that was aiming to investigate the prostheses with open-porous surface and trabecular structure, created by Selective Laser Melting.

    The purpose of the thesis was to investigate and characterize 30 different trabecular structures of Ti-6Al-4V, fabricated by Selective Laser Melting. That includes investigation the effect on the morphology and porosity fraction caused by the manufacturing and the effect on mechanical and physical properties due to the different characterizations of the structures.

    The thesis work had its foundation in literature studies to receive deep knowledge about the subject. Practical tests were performed to investigate mechanical behaviour under compressive and tensile loading, static friction and wear resistance. The findings from these tests were compared to the porosity fraction and the morphological characterizations.

    The result stated that the porosity fraction was lower than the designed porosity, and that is was strongly influenced by size of the voids and struts. The strut thickness was higher than the design values, especially on the lateral surface, while the voids size were approximately as designed. Result from the compression test showed a trend of decreasing stiffness and strength with increasing porosity fraction. Also structures with same porosity fraction could have a wide range in mechanical properties which indicates high dependence on the morphological geometry i.e. pore size and shape, strut size and pore distribution. Comparisons between tensile and compression behaviour stated that the structures had a lower strength but a significant higher stiffness in tensile load. All structures from the wear test showed a good resistance while the results from the friction test needs further investigation to be fully understood.

    The physical and mechanical properties of the trabecular structures was found to be close to those of cortical and trabecular bone in porosity, stiffness and strength. There is a range of variations leading to possibilities to adopt the application depending on customer. Thus, these can be considered as promising structures used biomedical application to optimize osseointegration and secondary long term fixation.
