  2. 16. Form and Finish of Implants in Uncemented Hip Arthroplasty : Effects of Different Shapes and Surface Treatments on Implant Stability

    Author : Stergios Lazarinis; Nils P. Hailer; Lars Weidenhielm; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Form; Finish; Total hip arthroplasty; Swedish Hip Arthroplasty Register; Hydroxyapatite; RSA; DXA; BMD; Stability.; Orthopaedics; Ortopedi;

    Abstract : The design of an uncemented hip arthroplasty implant affects its long-term survival. Characteristics such as the form and the finish of the implant are crucial in order to achieve the best possible conditions for long-term implant survival. READ MORE

  4. 17. Bioactive Surgical Implant Coatings with Optional Antibacterial Function

    Author : Mirjam Lilja; Maria Strømme; Håkan Engqvist; Håvard Haugen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydroxyapatite; titanium dioxide; photocatalysis; antibacterial effect; antibiotic release; biomimetic coating; co-precipitation; tobramycin;

    Abstract : Device associated infections are a growing problem in the field of orthopaedics and dentistry. Bacteria adhering to implant surfaces and subsequent biofilm formation are challenging to treat with systemic administered antibiotics. READ MORE

  5. 18. Evaluation of Biological Biomaterial Properties using Microfluidic Systems

    Author : Abdul Raouf Atif; Gemma Mestres; Séverine Le Gac; Uppsala universitet; []
    Keywords : Bone; Flow; Hydroxyapatite; In vitro; Modelling; On-chip; PDMS; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : Despite increased orthopedic biomaterial research activity over previous decades, relatively few novel biomaterials have made it to clinical use. This may partially be due to the inability of existing in vitro testing routines to sufficiently replicate the physiological environment, leading to potentially inaccurate assessments of a biomaterial’s therapeutic potential.

  6. 19. Bio-Nano Interactions : Synthesis, Functionalization and Characterization of Biomaterial Interfaces

    Author : Yixiao Cai; Xia Wei; Mikael Karlsson; Martin Andersson; Uppsala universitet; []
    Keywords : Bioactive surfaces; nanocrystalline diamond; hydroxyapatite; protein secondary structure; protein absorption; auditory neurons; single crystalline rutile; nano morphology; surface functionalisation; in vitro biomineralisation; translucent nano-ceramics; bio-window material; material characterisation.; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Current strategies for designing biomaterials involve creating materials and interfaces that interact with biomolecules, cells and tissues.  This thesis aims to investigate several bioactive surfaces, such as nanocrystalline diamond (NCD), hydroxyapatite (HA) and single crystalline titanium dioxide, in terms of material synthesis, surface functionalization and characterization.

  7. 20. Enhancing material and biological properties of calcium phosphate bone substitute

    Author : Christopher Camire; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; materialteknik; Non-metallic mineral technology; Icke-metallisk mineralteknik; Biotechnology; Bioteknik; Materiallära; Material technology; Technological sciences; Teknik; Naturvetenskap; reumatologi; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Natural science; muskelsystem; Skelett; muscle system; rheumatology locomotion; Bone Substitute; Calcium Phosphate; Skeleton; Medicin människa och djur ; Medicine human and vertebrates ; Osteoconductivity; Silicon; Mechanical Properties; Crystallinity; Reactivity; Calorimetry; Hydroxyapatite;

    Abstract : Calcium phosphate materials (CaPs) have proven biocompatible and useful in clinical situations. One CaP showing promise in the clinic is alpha phase tricalcium phosphate ([alpha]-TCP). [alpha]-TCP in powder form can be hydrated and undergoes a reaction resulting in calcium deficient hydroxyapatite (CDHA). READ MORE
