    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. 2. Injectable Biomaterials for Spinal Applications

    Författare :Alejandro López; Cecilia Persson; Håkan Engqvist; Andreas Boger; Uppsala universitet; []
    Nyckelord :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;

    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.

  4. 3. On hydroxyapatite modified peek implants for bone applications

    Författare :Pär Johansson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental Implants; Dentala implantat;

    Sammanfattning : People are living longer today than ever before, and the number of older adults will increase exponentially over the next coming years. However, that does not necessarily mean that they are living healthier. LÄS MER
