  2. 1. Mechanical analyses of trabecular bone and its interaction with implants

    Author : Dan Wu; Cecilia Persson; Hanna Isaksson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; Elastic modulus; Digital volume correlation; Pullout resistance; Micro-computed tomography.;

    Abstract : Bone substitute materials or implants are commonly used in the surgical treatment of bone fractures. However, severe complications are sometimes reported. READ MORE

  4. 2. Mechanical optimization of orthopaedic bone screw constructs

    Author : Yijun Zhou; Cecilia Persson; Benedikt Helgason; Philip Procter; Richie Gill; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; screw implant; explicit finite element modelling; computed tomography; numerical optimization; neural network; hydrogel; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

    Abstract : Orthopaedic screw implants are crucial in surgical procedures for bone structures, with a longstanding issue being screw loosening. Improving screw stability requires an enhanced understanding of the bone-implant interactions and associated failure mechanisms. This knowledge can be used to optimize screw designs. READ MORE

  5. 3. The role of physical activity on bone density and bone geometry in men

    Author : Martin Nilsson; Göteborgs universitet; []
    Keywords : bone mineral density; bone geometry; trabecular microarchitecture; physical activity; men;

    Abstract : THE ROLE OF PHYSICAL ACTIVITY ON BONE DENSITY AND BONE GEOMETRY IN MEN Introduction: Several studies indicate that peak bone mass, reached during the third decade in life, is an important determinant of osteoporosis later in life. Physical activity with dynamic loading of the bone is an important determinant of peak bone mass. READ MORE

  6. 4. Total knee arthroplasty : aspects on improved fixation in the younger patient

    Author : Anders Henricson; Kjell G Nilsson; Tore Dalén; Sören Toksvig-Larsen; Umeå universitet; []
    Keywords : Surgery; Total knee arthroplasty; total knee replacement; mobile bearing; trabecular metal; hydroxy-apatite coating; Kirurgi; Orthopaedics; ortopedi;

    Abstract : The results of total knee arthroplasty are inferior in younger patients. The challenge today is therefore to develop designs and concepts that will last at least 25 years. This thesis has evaluated the fixation to bone of modern designs of knee prostheses uring RSA analysis. READ MORE

  7. 5. Physical activity, bone gain and sustainment of peak bone mass

    Author : Taru Tervo; Anna Nordström; Peter Nordström; Jon Karlsson; Umeå universitet; []
    Keywords : BMD; physical activity; men; athletes; trabecular bone; cortical bone; self-perceived health; MEDICINE; MEDICIN; medicin; Medicine;

    Abstract : Weak and osteoporotic bones are an increasing cause of mortality and painful physical impairment among the elderly, especially in the Western world. Bone mineral density (BMD, g/cm2) accrual during childhood and adolescence is thought to influence an individual’s risk of osteoporosis and the related fractures. READ MORE
