Sammanfattning : The use of injectable biomaterials is growing as the demands for minimally invasive procedures, and more easily applicable implants become higher, but their availability is still limited due to the difficulties associated to their design.Each year, more than 700,000 vertebral compression fractures (VCF’s) are reported in the US and 500,000 VCF’s in Europe due to primary osteoporosis only.

Sammanfattning : Non-ionic, water-soluble, contrast media, iohexol and/or iodixanol, have been investigated for use in acrylic bone cement aimed for arthroplasty. Bone cement, containing the new particulate contrast media , was investigated for: quasi-static mechanical properties, water uptake properties, release of contrast media from the bone cement, biological responses from particulate bone cement, polymerisation reaction, polymerisation temperature, glass transition temperature, injectability and penetration into human cancellous bone, and radiopacity.

3. Orthogeriatric anaesthesia - studies on the bone cement implantation syndrome, risk prediction and intraoperative haemodynamics
Sammanfattning : The bone cementation implantation syndrome (BCIS), as seen in orthopaedic patients, is characterised by intraoperative hypotension and hypoxia and loss of consciousness around the time of bone cementation. In a retrospective study, the incidence of and risk factors for the BCIS and its impact on mortality during cemented hemiarthroplasty for hip fracture were evaluated. LÄS MER
4. Hip revisions with impacted morselized allograft bone and cement. Patient outcome, prosthetic fixation and risks
Sammanfattning : 144 consecutive hip revisions performed with morselized allograft bone and cement were followed up to 5 years after surgery. In 49 hips patient outcome was evaluated with the Nottingham Health Profile (NHP) questionnaire and Charnley hip scores in 47 hips prosthetic fixation was evaluated with radiostereometry (RSA)and in all 144 hips risks and complications were recorded using a prspective protocol.

Sammanfattning : Acrylic bone cement based on poly(methyl methacrylate) (PMMA) is commonly used during vertebral augmentation procedures for the treatment of osteoporosis-induced vertebral compression fractures. However, the high stiffness of the cement compared to that of the surrounding trabecular bone is presumed to facilitate the formation of new fractures shortly after surgery. LÄS MER
