  1. 6. Injectable calcium sulphate and calcium phosphate bone substitutes

    Författare :Malin K Nilsson; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; ortopedi; Kirurgi; Surgery; orthopaedics; traumatology; resorbable; hydroxyapatite; bone substitute; calcium phosphate; injectable; calcium sulphate;

    Sammanfattning : Two formulations of biphasic injectable bone substitutes have been developed for the treatment of bone defects and stabilisation of fragility fractures. The first formulation consists of a calcium sulphate matrix with embedded hydroxyapatite (HA) particles to provide osteoconductivity. LÄS MER

  3. 7. The effects of cyclosporin A on bone turnover and repair

    Författare :Anders Ekelund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cyclosporin A; osteoinduction; osteoconduction; bone turnover; fracture healing; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : The effects of cyclosporin A on bone metabolism are unclear and controversial. The aims of this thesis were to study the effects of cyclosporin A on bone turnover and on different repair processes such as fracture healing, osteoinduction and osteoconduction. LÄS MER

  4. 8. SURFACE PROPERTIES OF IMPLANTS MANUFACTURED USING ELECTRON BEAM MELTING

    Författare :Rebecca Klingvall Ek; Lars-Erik Rännar; Mikael Bäckström; Jaan Hong; Felicia Suska; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron beam melting; blood coagulation; bone ingrowth; surface roughness; process parameters;

    Sammanfattning : This thesis summarizes the results concerning the manufacture of medical implants for bone replacement using electron beam melting (EBM) which is an additive manufacturing (AM) technology, and aims to satisfy the engineering needs for the medical functionality of manufacturing technology. This thesis has focused on some microscopic properties for surfaces and bone integration. LÄS MER

  5. 9. Bone Development and the Nervous System

    Författare :Gregor Sisask; Olof Nilsson; Anders Bjurholm; Kenneth B Jonsson; André Stark; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Cellbiologi;

    Sammanfattning : Innervation of bone influence bone modeling, growth and remodeling. Pro-inflammatory cytokines released after tissue trauma are recognized as neurotrophic factors as well as factors influencing bone formation. The Wnt signaling pathway, essential for cell migration during embryogenesis is found to influence bone formation during fracture healing. LÄS MER

  7. 10. On Bone Regeneration in Porous Bioceramics - Studies in humans and rabbits using free form fabricated scaffolds

    Författare :Johan Malmström; Göteborgs universitet; []
    Nyckelord :bone regeneration; hydroxyapatite; zirconia; macroporosity; microporosity; free form fabrication; focused ion beam; scanning electron microscopy; transmission electron microscopy; rabbit; human;

    Sammanfattning : The objective of the present thesis was to evaluate the effect of material chemistry and macroand micro-porosity on bone regeneration in association with synthetic, porous ceramic materials. Ceramic scaffolds were designed and manufactured for experimental and human studies using free form fabrication (FFF), a technique which produces the object layer by layer using data from CAD files.
