  1. 1. Injectable Biomaterials for Spinal Applications

    Author : Alejandro López; Cecilia Persson; Håkan Engqvist; Andreas Boger; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; injectable; biomaterials; bone cement; vertebral compression fractures; spine; radiopacity; minimally invasive treatment; low-modulus cement; oligomer; PMMA; calcium phosphate; vertebroplasty; bone; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : 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.

  2. 2. Non-ionic contrast media in acrylic bone cement

    Author : Fred Kjellson; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; Material technology; Materiallära; materialteknik; PMMA; Bone cement; particle size; contrast media; radiopacity; iohexol; iodixanol; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; orthopaedics; Surgery; medicinsk instrumentering;

    Abstract : 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. 3. Orthogeriatric anaesthesia - studies on the bone cement implantation syndrome, risk prediction and intraoperative haemodynamics

    Author : Fredrik Olsen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone cement implantation syndrome; cemented hip hemiarthroplasty; bone cement; Nottingham hip fracture score; cardiac output monitoring; continuous spinal anaesthesia;

    Abstract : 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. READ MORE

  4. 4. Hip revisions with impacted morselized allograft bone and cement. Patient outcome, prosthetic fixation and risks

    Author : Ewald Ornstein; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiostereometry; NHP; patient outcome; cement; allograft; morselized; impacted; bone transplantation; hip; Arthroplasty; revision; complications; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : 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.

  5. 5. Exploring microfluidics as a tool to study cell-biomaterial interactions

    Author : Sarah-Sophia Carter; Gemma Mestres; Marlon Schneider; Uppsala universitet; []
    Keywords : Bone; Cement; Flow; Hydroxyapatite; In vitro; On-chip; Titanium; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

    Abstract : Considering the tremendous amount of research on the development of novel biomaterials, relatively few of these have reached the patient. This can at least in part be explained by the lack of predictive power of the currently used in vitro models, which are nowadays recognized to be too reductionist to accurately predict in vivo complexity.
