  2. 1. Distal femur fracture in the elderly patient

    Author : Martin Paulsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Distal femur fracture; Geriatric patients; Weight-bearing; Recovery; Secondary displacement; Minimally invasive plate osteosynthesis MIPO ; Fracture alignment; Fracture classification;

    Abstract : Studies on the epidemiology of distal femur fractures show a vast increase in low-energy trauma-associated fractures in older ages. Age-related changes in bones lead to loss of bone matrix and increased porosity, which entails an increased risk for fractures and different fracture patterns than in younger individuals. READ MORE

  4. 2. Hip fractures : A biomechanical analysis of fracture strength prediction, prevention, and repair

    Author : Joeri Kok; Avdelningen för Biomedicinsk teknik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element; Bone cement; Femur; Fracture; Experimental mechanics; X-ray imaging;

    Abstract : Due to the aging population, hip fracture incidence has been increasing over the past decades. Measurements of bone mineral density with dual energy X-ray absorptiometry are the gold standard for hip fracture risk assessment, where patients with a low bone density have a high risk of fracture.

  5. 3. Multiscale Modelling of Proximal Femur Growth : Importance of Geometry and Influence of Load

    Author : Priti Yadav; Elena Gutierrez Farewik; Marco Viceconti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone tissue modeling; deformity; biomechanics; osteogenic index; poroelastic material; octahedral shear stress; hydrostatic stress; fluid velocity; octahedral shear strain; MRI; walking; jumping; sedentation; Engineering Mechanics; Teknisk mekanik;

    Abstract : Longitudinal growth of long bone occurs at growth plates by a process called endochondral ossification. Endochondral ossification is affected by both biological and mechanical factors. READ MORE

  6. 4. Femoral Strength Prediction using Finite Element Models : Validation of models based on CT and reconstructed DXA images against full-field strain measurements

    Author : Lorenzo Grassi; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone strength; femur; osteoporosis; statistical appearance model; finite element; mechanical test;

    Abstract : Osteoporosis is defined as low bone density, and results in a markedly increased risk of skeletal fractures. It has been estimated that about 40% of all women above 50 years old will suffer from an osteoporotic fracture leading to hospitalization. READ MORE

  7. 5. On the importance of nanometer structures for implant incorporation in bone tissue

    Author : Lory Melin Svanborg; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Introduction Replacing lost teeth with dental implants is today a reliable treatment method associated with good long-term clinical results. Different surface modifications alter the surface topography at micro- and nanometer level of resolution as well as chemical properties, which have shown to be of importance for osseointegration.
