  4. 7. Aspects of fracture prevention - The role of fracture liaison services and alendronate

    Author : Kristian F Axelsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoporosis; Prevention; Fracture; Fracture liaison service; Alendronate; Elderly; Prednisolone;

    Abstract : Objective: In an ageing population, osteoporotic fractures become more common and cause increased morbidity, mortality and societal cost. This thesis aimed to determine the potential role of fracture liaison services (FLS) and alendronate treatment on fracture risk in those with a recent fracture, in the elderly and in those treated with oral prednisolone.

  5. 8. 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

  6. 9. Hydro-Mechanical Behaviour of a Pressurised Single Fracture: An In-situ Experiment

    Author : Patrik Alm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydro-mechanical behaviour; hydraulic field test; transmissivity; effective stress; aperture; fracture stiffness; fracture; slug test;

    Abstract : Exploration of ground water resources, grouting, disposal of nuclear waste and extraction of geothermal energy are examples of activities which require consideration of the relationship between effective stress and transmissivity. However, this relationship is poorly understood and very few investigations have been conducted in field scale. READ MORE

  7. 10. Aspects of bone quality and risk assessments in fracture and elective orthopaedic patients

    Author : Camilla Bergh; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fracture; Fracture incidence; Epidemiology; Mortality; Osteoporosis; Frailty; Spinal stenosis; Bone quality; Bone mineral density;

    Abstract : Background: Bone quality, bone strength, and bone remodelling are important in many orthopaedic conditions and can have an impact on fracture incidence, bone healing, implant failure, and different outcome aspects. There is relatively sparse information on fracture incidence and mortality both for all fractures compiled and for some of the individual fracture locations. READ MORE
