  1. 1. Static and Dynamic Load Response of the Lumbar Spine in Flexion

    Författare :Anna-Lisa Osvalder; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanical response; flexion-distraction injuries; injury; ; experimental methods; spinal segments;

    Sammanfattning : The aims of this study were to develop experimental methods for static and dynamic loading of spinal segments in vitro that would simulate flexion-distraction injuries (lap seat-belt injuries) and increase knowledge about the biomechanical response and the mechanisms of injury of the lumbar spine under static and dynamic (transient) loads in flexion. The experiments were carried out on the lumbar functional spinal unit (FSU) consisting of two adjacent vertebrae, the intervertebral disc and all intervening ligaments. LÄS MER

  3. 2. Osteoporosis in elderly women; Bone traits, fracture and the PTH gene complex

    Författare :Max Tenne; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osteoporosis; fracture; parathyroid hormone; gene; polymorphism; dual energy X-ray absorptiometry; bone mineral density; hip strength analysis;

    Sammanfattning : Background: Fragility fractures are a major health problem world wide and the numbers are growing due to ageing populations. Early identification of individuals at risk for osteoporosis and fracture, enabling preventive measures and treatment is essential. LÄS MER

  4. 3. Physical Activity, Bone Mass and Bone Structure in Pre-pubertal Children

    Författare :Gayani Alwis; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone size; BMD; BMC; hip structure analysis; DXA; boys; Physical activity; girls; acclerometers; school transportation;

    Sammanfattning : Low bone mineral density (BMD) is a risk factor for fractures and much of the fracture preventive effort today is devoted to preventing low BMD. Physical activity (PA) has been described as one of the best strategies to optimize skeletal development in the growing child. LÄS MER

  5. 4. Assessment of skeletal structure by MR relaxometry

    Författare :Torkel B Brismar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :magnetic resonance imaging; bone and bones; osteoporosis;

    Sammanfattning : Introduction: More than 40 per cent of all women older than 50 years will suffer from a hip, wrist or vertebral fracture. Most of these fractures are related to bone fragility, osteoporosis. If the disease is diagnosed and treated at an early stage the risk of fracture can be decreased. LÄS MER

  7. 5. Diabetic osteopathy : a study in the rat

    Författare :Tashfeen Ahmad; Karolinska Institutet; Karolinska Institutet; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diabetes mellitus type 2; Goto-Kakizaki rat; bone mineral density; insulin-like growth factor-I; insulin-like growth factor binding protein 1; insulin-like growth factor binding protein 4; peripheral neuropathy; substance P; calcitonin gene-related peptide; neuropeptide Y; Diabetes mellitus type 2;

    Sammanfattning : The present study on non-obese Goto-Kakizaki (GK) rats with type-2 diabetes and neuropathy was an attempt to describe and define pertinent features of diabetic osteopathy. Altogether, the study included 33 GK rats aged 12 and 20 months, and 36 age-matched Wistar rats as controls. LÄS MER
