  1. 21. Total knee arthroplasty : Alternative aspects on fixation, design and postoperative treatment

    Författare :Gunnar Adalberth; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Total knee arthroplasty; RSA; migration; all-polyethylene; drainage; cement; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : Total knee arthroplasty as a treatment of severe gonarthrosis has become a great success, but tibial component loosening is still a major reason for failure. When total knee arthroplasty was introduced, only all-polyethylene (AP) tibial components were available. LÄS MER

    Sammanfattning : The overarching objective of this thesis was to develop intervertebral implants for degenerated discs through design, fabrication, and mechanical validation. The research had four primary aims, each addressing different facets of implant development. LÄS MER

  3. 23. Revision hip arthroplasty using impacted allograft bone and cement. Studies on prosthetic stability and outcome

    Författare :Vasileios Zampelis; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Revision hip arthroplasty; impaction bone grafting;

    Sammanfattning : För 50 år sedan började man operera utslitna höftleder och använda konstgjordaledytor som ersättning. Antalet operationer har långsamt ökat och operationen är nu en av de vanligaste i Sverige. En ny höftled leder oftast till total smärtfrihetoch ökad rörelseförmåga under lång tid men ibland kan de insatta delarna lossna. LÄS MER

  4. 24. Additives Increasing the Bone-Forming Potential around Calcium Phosphate Cements : Statin, Strontium and Silicon

    Författare :Maryam Montazerolghaem; Marjam Karlsson Ott; Håkan Engqvist; Pedro Granja; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium Phosphate Cements; Osteoblast; Osteoclast; Monetite; Zebrafish; Simvastatin; Strontium; Silicon; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : More than one million people worldwide receive some kind of bone graft each year. Grafts are often needed following bone tumour removal or traumatic fractures to fill voids in the bone and to aid in the healing process. LÄS MER

  5. 25. The role of microstructure for crack propagation in cortical bone

    Författare :Anna Gustafsson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crack deflection; Interface; Mechanical testing; Micro-CT; Osteon; Porosity; XFEM;

    Sammanfattning : Healthy cortical bone tissue is both tough and strong and has a unique ability to resist fracture. One reason is the hierarchical structure of the tissue where toughening mechanisms at all length scales act to slow down or stop a propagating crack. LÄS MER
