  1. 6. Craniofacial bone reconstruction with bone morphogenetic protein-2

    Författare :Ann-Charlott Docherty Skogh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :bone morphogenetic protein;

    Sammanfattning : Bone defects in the craniofacial area are a clinical challenge and can be the result of trauma, tumour resection or congenital malformations. The golden standard for reconstruction is autologous bone grafts, but bone may not always be readily available and donor-site morbidity might follow. LÄS MER

  3. 7. Revision Hip Arthroplasty : Impaction Bone Grafting and Low-Dose CT-Based Measurements of Bone Density and Migration

    Författare :Hampus Stigbrand; Gösta Ullmark; Nils Hailer; Per Wretenberg; Uppsala universitet; []
    Nyckelord :Revision Hip Arthroplasty; Bone Grafting; Computed Tomography; Bone Mineral Density; CTMA; Orthopaedics; Ortopedi;

    Sammanfattning : Aseptic loosening of total hip replacements is always associated with bone defects, either due to removal of the existing implant or osteolysis. Bone defects can be handled during revision surgery with impaction bone grafting (IBG). LÄS MER

  4. 8. Effects of silicon on bone. Clinical observations and experimental cell studies

    Författare :Catarina Magnusson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; silicon; osteoclast; pregnancy; lactation; bone metabolism; bone regeneration;

    Sammanfattning : Bone health has a major impact on life quality. In Sweden, osteoporosis is a highly prevalent skeletal disease that primarily affects the elderly, causing fragility fractures and pain. LÄS MER

  5. 9. Effects of antiresorptive agents on inflammation and bone regeneration in different osseous sites - experimental and clinical studies

    Författare :Carina Cardemil; Peter Thomsen; Cecilia Larsson Wexell; Bente Brokstad Herlofson; Göteborgs universitet; []

    Sammanfattning : The biological mechanisms involved in bone regeneration in osteoporotic bone and the effect of antiresorptive drugs in relation to surgically inserted biomaterials are not fully understood. Improved osseointegration of titanium implants but also adverse effects of antiresorptive therapies, such as osteonecrotic jaw have been described in the literature. LÄS MER

  7. 10. Biological interface of bone graft substitute materials : experimental studies on interactions between biomaterials and bone cells

    Författare :Zivko Mladenovic; Maria Ransjö; Joost D de Brujin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Bone graft substitute materials are becoming more common as alternative therapy strategies when bone defects in patients need to be treated. The interaction between bone cells and biomaterials occur at the surface of the materials. A great deal is known about the importance of surface topography and physic-chemical properties of biomaterials. LÄS MER
