1. 1. 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

3. 2. 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

4. 3. BMP implants in bone formation. Studies in rabbits and rats

   Författare :Charlotte Jeppsson; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ortopedi; traumatologi; graft resorption.; Kirurgi; Surgery; orthopaedics; traumatology; bone formation; bone graft; hydroxyapatite; collagen; bisphosphonate; rat; rabbit; titanium chamber; BMP; TGF-ß;

   Sammanfattning : Bone morphogenic proteins, BMPs, are a group endogenous proteins that are highly conserved through evolution. The amino acid sequences of about 15 different BMPs are now known and recombinant human BMPs are commercially available. Implantation of an individual BMP protein is sufficient to induce bone formation even at a subcutaneous site. LÄS MER

5. 4. 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

7. 5. Allograft bone in hip revision: the effect of locally applied pharmacological treatment

   Författare :Ola Belfrage; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allograft bone; bone transplantation; bisphosphonate; bone morphogenetic proteins; hip revision; radiostereometric analysis;

   Sammanfattning : The clinical success of primary hip replacement is paramount but the need for revisions will continue to increase due to the increasing number of operated individuals. In Sweden, the number of hip revisions in 2012 exceeded 2,300. During implant loosening, some of the bone in the femur is lost, which can make the revision more difficult. LÄS MER
