  1. 1. 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

  3. 2. Hip Revision Surgery : Identification of Genetic Markers and Evaluation of Novel Treatment Strategies

    Författare :Anders Brüggemann; Nils Hailer; Hans Mallmin; Karl Michaëlsson; Olle Nilsson; Per Wretenberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Total hip arthroplasty (THA) is, despite its overall good outcome, for some patients followed by hip revision surgery. This seems in parts to be because of genetic susceptibility to revision surgery. The most common reason for revision surgery is aseptic loosening followed by periprosthetic joint infection and dislocation. LÄS MER

  4. 3. On loosening and revision in total hip arthroplasty

    Författare :Thomas Eisler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Aseptic loosening; osteolysis; septic loosening; revision; revision total hip arthroplasty; total hip arthroplasty;

    Sammanfattning : Periprosthetic bone resorbtion (osteolysis) and aseptic loosening constitute the major long-term complication in total hip arthroplasty. It has been suggested that osteolysis is the result of the action of osteoclasts generated by prosthetic wear-debris-triggered macrophages. LÄS MER

  5. 4. Morcelised Impacted Cortico-Cancellous Bone Allografts in Revision Surgery for Endoprosthetic Loosening with Osteolysis

    Författare :Gösta Ullmark; Johan Kärrholm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Total hip arthroplasty; total knee arthroplasty; graft impaction; revision; histology; biomechanic; cement; positron emission tomography; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Revision total hip arthroplasty (RTHA) and filling of the bone defects with impacted particulated bone allograft is the concept that has been studied in this thesis. In three in vitro models, biomechanical aspects of morcelised and impacted bone allografts were studied. LÄS MER

  7. 5. 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.
