  1. 1. The Anabolic - Anti-catabolic Paradigm of Augmenting Skeletal Regeneration: A Bone Quality Perspective

    Detta är en avhandling från Department of Biomedical Engineering, Lund university

    Författare :Neashan Mathavan; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2017-05-08]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone fracture; Fracture healing; bone quality; Bone biomechanics; bone morphogenetic protein-7; Zoledronate; skeletal regeneration;

    Sammanfattning : Successful fracture repair is a complex series of coordinated processes leading to regeneration of new bone to bridge the fracture site, remodelling of the newly formed bone and restoration of skeletal function. Disruption of these processes occurs in approximately 10% of all fractures and leads to delayed or failed healing requiring surgical interventions, increased complication rates, prolonged rehabilitation and high morbidity.

  2. 2. Bone and Aluminium

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Hans-Olov Hellström; Uppsala universitet.; [2007]
    Nyckelord :Surgery; Aluminium; Osteoporosis; Hip fracture; Osteoporotic fracture; Alzheimer´s dementia; Bone mineral density; Bone mineral content; Mortality risk; Biomechanics; Inductively coupled mass spectrometry; Kirurgi;

    Sammanfattning : Osteoporosis is a major health care problem, by reason of its devastating consequences, in particular hip fractures. Worldwide it has been estimated that the incidence of hip fracture will increase to more than 6 million per year by 2050 compared to 1.7 million per year in 1990. LÄS MER

  3. 3. On the influence of micro-and macroscopic surface modifications on bone integration of titanium implants

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Patricia Miranda Burgos; Göteborgs universitet.; Gothenburg University.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium; dental implants; surface modification; bone tissue; biomechanics; BMP-2;

    Sammanfattning : Background: Osseointegrated titanium implants are routinely used in clinical denstistry as anchorage units for dental prostheses. Although the overall clinical results are good, there are clinical situations when an optimized implant healing is desirable, for instance in order to shorten healing periods and to allow immediate loading.

  4. 4. On the role of surface properties for implant fixation : From finite element modeling to in vivo studies

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Patrik Stenlund; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Implant stability; Removal torque; Surface roughness; Surface chemistry; Finite element analysis; Experimental; In vivo; Osseointegration; Mechanical loading; Bone regeneration; Biomechanics;

    Sammanfattning : The aim of this thesis was to gain a deeper understanding of the factors contributing to the fixation of bone-anchored implants, especially with regard to surface chemistry, surface topography and implant loading. The methodology used in the thesis ranges from systematic bench studies, computer simulations, experimental in vivo studies, to load cell measurements on patients treated with bone-anchored amputation prostheses.

  5. 5. Internal fixation of femoral neck fractures

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Leif Hernefalk; Linköpings universitet.; Linköpings universitet.; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Femoral neck fracture; osteotomy; internal fixation; device; technical principles; scintimetry; radiography; biomechanics; malposition; malreduction; complications; bone necrosis; revascularization; segmental collapse; non-union; elderly; osteoporosis; MEDICINE; MEDICIN;

    Sammanfattning : The incidence of femoral neck fractures in elderly people is rising requiring large health care resources. Internal fixation of the fracture is the treatment of choice in Scandinavia, but in 20-40% of the cases a late complication such as a segmental collapse of the femoral head after initial bone necrosis, or a non-union of the fracture because of non-healing, will occur.
