  1. 11. Tissue responses to bone-implant biomaterials

    Författare :Haihong Liao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Gene expression; interface; mineralization; nacre; osteoblast; osteoclast; titanium;

    Sammanfattning : The purpose of the studies was to understand the mechanisms which underlie the interaction between tissue and bone-implant biomaterials. Tissue and naturally occurring aragonite nacre interaction was systematically studied for the first time by combined histological examination, cellular and molecular biological approaches. LÄS MER

  3. 12. On the biological behavior of barrier membranes: implications for Guided Bone Regeneration. Clinical and Experimental studies

    Författare :Alberto Turri; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Guided Bone Regeneration; Membranes;

    Sammanfattning : There is a continuous development of bone augmentation solutions to meet the rising demand for effective dental implant rehabilitations. One of the most used techniques is Guided Bone Regeneration (GBR). LÄS MER

  4. 13. On the aetiology of aseptic loosening in joint arthroplasties, and routes to improved cemented fixation

    Författare :Mikael Sundfeldt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; knee prosthesis; aseptic loosening; polyethylene particles; endotoxin; bone cement; sodium fluoride;

    Sammanfattning : Background: Aseptic loosening is the most common single cause for revisions in major joint arthroplasties worldwide. Different theories for aseptic loosening have been discussed during the last two decades. There is a need for improving fixation in both cemented and uncemented implants. LÄS MER

  5. 14. On Fixation of Hip Prostheses

    Författare :Lars Palm; Ingemar Ivarsson; Ola Wahlström; Jan Milbrink; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fixation; Hip prostheses; primary arthroplasty; revision arthroplasty; cemented; uncemented; bone grafting; Fixation; Höftprotes; primärartroplastik; revisionsartroplastik; cement; cementfri; bentransplantation; Orthopaedics; Ortopedi;

    Sammanfattning : This thesis, comprising 5 separate studies, is concerned with fixation of prosthetic components in total hip arthroplasty. The results and conclusions of the studies fol-low;The initial stability of femoral revision components, the long cementless PCA stem and the Exeter standard stem cemented in a bed of impacted bone graft, was com-pared in an experimental study.

  7. 15. The morselized and impacted bone graft. Animal experiments on proteins, impaction and load

    Författare :Magnus Tägil; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; load; growth factors; graft healing; remodeling; allograft; Impaction grafting; morselized graft; Kirurgi; ortopedi; traumatologi; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : This thesis focuses on the healing and remodeling of the morselized and impacted bone allograft, commonly used in revision of loosened hip prostheses with osteolysis. The influence on remodeling by the impaction procedure per se was analyzed, as well as the effects of endogenous bone graft proteins, and an exogenously applied growth factor (OP-1). LÄS MER
