1. 1. Hands-on osteoporosis screening with digital x-ray radiogrammetry

   Författare :Michael Wilczek; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : According to epidemiological studies about one third of women and one fifth of men over 50 years will experience a fragility fracture. These fractures account for substantial mortality, morbidity and health care cost. Osteoporosis is a silent disease and thus often goes undiagnosed for a long time. LÄS MER

3. 2. Physical activity and regional bone mass

   Författare :Håkan Magnusson; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; medial tibial stress syndrome; hip fracture; weight-loaded and unloded skeletal regions; physical activity; Bone mineral density; dual X-ray absorptiometry; ortopedi; Kirurgi; traumatology; traumatologi;

   Sammanfattning : This thesis considers the effect of physical activity on bone mass in weight-loaded and unloaded regions of the skeleton. Bone mass was measured by Dual X-ray Absorptiometry (DXA) and by Quantitative Ultrasound (QUS). LÄS MER

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

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

   Sammanfattning : 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. 4. 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

7. 5. Mild primary hyperparathyroidism - Long-term effects of parathyroidectomy versus observation - with emphasis on skeletal outcomes

   Författare :Karolina Lundstam; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; primary hyperparathyroidism; parathyroidectomy; observation; vertebral fractures; peripheral fractures; kidney stones; radiography; bone mineral density; dual-energy x-ray absorptiometry; mortality;

   Sammanfattning : Background: The majority of patients with primary hyperparathyroidism (PHPT) in developed countries today present with no obvious symptoms, i.e. the mild form of the disease. LÄS MER
