2. 1. The morselized and impacted bone graft. Animal experiments on proteins, impaction and load

   Author : Magnus Tägil; Lund Ortopedi; []
   Keywords : 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;

   Abstract : 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). READ MORE

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

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

   Abstract : 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). READ MORE

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

   Author : Gösta Ullmark; Johan Kärrholm; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. On Fixation of Hip Prostheses

   Author : Lars Palm; Ingemar Ivarsson; Ola Wahlström; Jan Milbrink; Linköpings universitet; []

   Abstract : 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. 5. Revision hip arthroplasty using impacted allograft bone and cement. Studies on prosthetic stability and outcome

   Author : Vasileios Zampelis; Lund Ortopedi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Revision hip arthroplasty; impaction bone grafting;

   Abstract : För 50 år sedan började man operera utslitna höftleder och använda konstgjordaledytor som ersättning. Antalet operationer har långsamt ökat och operationen är nu en av de vanligaste i Sverige. En ny höftled leder oftast till total smärtfrihetoch ökad rörelseförmåga under lång tid men ibland kan de insatta delarna lossna. READ MORE
