    Author : Fred Kjellson; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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.

  2. 2. Injectable Biomaterials for Spinal Applications

    Author : Alejandro López; Cecilia Persson; Håkan Engqvist; Andreas Boger; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.
