  1. 16. Fracture of the distal radius - outcome, primary surgery and treatment of malunion

    Författare :Antonio Abramo; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone substitute; surgery; DASH; Cerament; Distal radius fracture; Hydroxy apatite; Norian; malunion; TriMed; outcome;

    Sammanfattning : A consensus protocol for treatment of distal radius fractures (DRF) has been developed to aid clinicians in treatment decision making. The protocol was evaluated in Paper I using a validated subjective outcome instrument, DASH in 518 consecutive patients. LÄS MER

  3. 17. MESENCHYMAL STEM- AND STROMAL CELLS IN BONE MARROW AND OSTEOSARCOMA

    Författare :Jan Claas Brune; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mesenchymal stem cells; stromal cells; bone marrow stem cells; tumour stroma; stroma-directed anti-tumour therapy; osteosarcoma;

    Sammanfattning : Primary mesenchymal stem cells (MSC) play a central role in bone marrow (BM) and during haematopoiesis. Yet, the exact phenotype and spatial distribution of primary MSC in the human BM are unknown. Their cultured progeny are promising candidates for clinical applications. LÄS MER

  4. 18. Clinical and experimental studies of bone substitutes and dental implants in compromised bone sites

    Författare :Amela Trbakovic; Andreas Thor; Patricia Hedenqvist; Christer Dahlin; Uppsala universitet; []
    Nyckelord :clinical follow-up; calcium phosphates; rabbit model; sinus lift; radius model; in vivo; bisphosphonates; narrow diameter implants; dental implants; Oral and Maxillofacial Surgery; Käkkirurgi;

    Sammanfattning : Background: With an ageing population, an increase of more challenging implant treatments is expected. In this thesis, we evaluate the outcome of two faster implant protocols, in patients with compromised alveolar bone. LÄS MER

  5. 19. Magnetic resonance imaging with ultrashort echo time as a substitute for X-ray computed tomography

    Författare :Adam Johansson; Tufve Nyholm; Karlsson Mikael; James Balter; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic resonance imaging; computed tomography substitute; ultrashort echo time; parallel imaging; radial imaging; radiofysik; radiation physics;

    Sammanfattning : Radiotherapy dose calculations have evolved from simple factor based methods performed with pen and paper, into computationally intensive simulations based on Monte Carlo theory and energy deposition kernel convolution.Similarly, in the field of positron emission tomography (PET), attenuation correction, which was originally omitted entirely, is now a crucial component of any PET reconstruction algorithm.

  7. 20. Additives Increasing the Bone-Forming Potential around Calcium Phosphate Cements : Statin, Strontium and Silicon

    Författare :Maryam Montazerolghaem; Marjam Karlsson Ott; Håkan Engqvist; Pedro Granja; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium Phosphate Cements; Osteoblast; Osteoclast; Monetite; Zebrafish; Simvastatin; Strontium; Silicon; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : More than one million people worldwide receive some kind of bone graft each year. Grafts are often needed following bone tumour removal or traumatic fractures to fill voids in the bone and to aid in the healing process. LÄS MER
