1. 1. Defining the clinical usefulness of vertebral fracture assessment

   Författare :Lisa Johansson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vertebral fracture; vertebral fracture assessment; osteoporosis; DXA; HRpQCT; bone microindentation; mild vertebral fracture; physical function; fracture risk; incident fracture; older women;

   Sammanfattning : Objective: Vertebral fractures (VFs) are the most common osteoporotic fracture and among the strongest predictors for future fracture. VFs can be identified by vertebral fracture assessment (VFA) from lateral spine imaging (LSI) by dual-energy X-ray absorptiometry (DXA). LÄS MER

3. 2. Malleus fracture : experimental and clinical aspects

   Författare :Anders Niklasson; Krister Tano; Magnus Von Unge; Preben Homøe; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; malleus fracture middle ear human temporal bone laser doppler vibrometry; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

   Sammanfattning : Background: Patients with malleus fractures are described as rare in the literature. The cause of these fractures are most commonly trauma and digital manipulation of the ear canal, while in some cases the causes are unknown. LÄS MER

4. 3. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation

   Författare :Christer Stenström; Pär Jonsén; Kjell Eriksson; Ugo Galvanetto; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peridynamics; J-integral; Essential work of fracture; Nonlocal methods; Meshless; Meshfree; Fracture; Crack tip; Exact analytical; Center cracked tension; Double edge notched tensile; fracture toughness; Peridynamik; Brottmekanik; Sprickspets; Brottseghet; Spänningsintensitet; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Fracture toughness is one of the most important properties of a material. Being able toaccurately estimate the energy that goes into forming new crack surfaces is essential for the development of new materials, quality assurance, structural monitoring and failure analysis.

5. 4. Experimental studies on fracture healing. Biological and biomechanical aspects

   Författare :Hans Mark; Göteborgs universitet; []
   Nyckelord :fracture; intramembranous; endochondral; ossification; neovascularization; fracture fixation; fracture stability;

   Sammanfattning : Considerable advances have been made in the knowledge regarding fracture healing and treatment duringrecent decades. Nevertheless, in 5-10 per cent of fractures, there are healing complications leading to complextreatment conditions, discomfort for patients and considerable costs. LÄS MER

7. 5. The influence of alcohol on bone metabolism and fracture healing

   Författare :Fredrik Nyquist; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kirurgi; traumatology; orthopaedics; Surgery; fracture prediction.; fracture healing; bone mineral density; Alcohol; post-traumatic osteopenia; fracture; ortopedi; traumatologi; Skeleton; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi;

   Sammanfattning : The influence of alcohol on bone metabolism, fracture and fracture healing was evaluated in men and male rats by measurements of bone mineral density (BMD), biochemical markers and biomechanical testings. Retrospectively, 199 male patients hospitalized for tibia shaft fractures were studied. Forty-nine were judged as problem drinkers. LÄS MER
