2. 1. The acute osteoporotic vertebral compression fracture. Its natural course and characteristics

   Author : Nobuyuki Suzuki; Göteborgs universitet; []
   Keywords : Vertebral body fracture; Osteoporosis; Pain; Quality of life; Disability; Compression fracture; Prognosis; Treatment; Prevalent fracture; Epidemiology;

   Abstract : Aim: The overall aim of this thesis was to investigate the natural course and the characteristics of the acute osteoporotic vertebral compression fracture in order to better understand and improve treatment for this type of fracture. Patients and methods: Eligible patients were all patients over 40 years of age who sought medical care at the emergency unit at Sahlgrenska University Hospital (studies I-III) or referred to the X-ray Department at Capio Diagnostic Center (study IV) because of back pain with a radiographically-confirmed acute vertebral body fracture which resulted from a low energy trauma.

4. 2. 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

5. 3. Fall-Related Hip Fracture : Predisposing and Precipitating Factors

   Author : Breiffni Leavy; Liisa Byberg; Anna Cristina Åberg; Michaëlsson Karl; Melhus Håkan; Ann Bremander; Uppsala universitet; []
   Keywords : Co-existing disease; Epidemiology; Fall circumstances; Hip fracture; In-depth interviews; Mixed methods; Physical activity perceptions; Psychotropic drugs; Qualitative; Orthopaedics; Ortopedi; Epidemiologi; Epidemiology; Geriatrics; Geriatrik; Physiotherapy; Sjukgymnastik fysioterapi;

   Abstract : A physically inactive lifestyle is a predisposing risk factor for fall-related hip fracture. The circumstances, or precipitating factors, surrounding hip fractures are, however, not well understood, a factor of relevance for Swedish adults who have one of the highest hip fracture risks in the world.

6. 4. Rheocasting of aluminium alloys : Process and components characteristics

   Author : Mostafa Payandeh; Anders E. W. Jarfors; Magnus Wessén; Helen Atkinson; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheocasting; aluminium alloy; RheoMetal TM process; microstructural characteristics; component properties and performance; robust design process;

   Abstract : Semi-Solid Metal (SSM) casting is a promising technology offering an opportunity to manufacture net-shape, complex geometry metal components in a single operation. However, the absence of foundry guidelines and limited design data for SSM casting makes it challenging to predict the performance of both process and components. READ MORE

7. 5. Defects and Surfaces and their Impact on Fatigue Behaviour of Powder Bed Fused Ti-6Al-4V : Characteristics and Modelling

   Author : Viktor Sandell; Marta-Lena Antti; Pia Åkerfeldt; Thomas Hansson; Stefano Beretta; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Defects; Additive Manufacturing; Ti-6Al-4V; Probabilistic Modelling; Fatigue; Extreme Value Statistics; Materialteknik; Engineering Materials;

   Abstract : Additive manufacturing (AM), of metals is gaining popularity as an alternative to conventional manufacturing techniques such as casting and forging. Metal-AM allows for the production of complex part geometries with reduced material waste and shorter lead times. READ MORE
