  1. 21. Wear and Loosening in Cemented Hip Arthroplasty

    Författare :Uldis Kesteris; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ortopedi; Kirurgi; traumatology; orthopaedics; Surgery; traumatologi;

    Sammanfattning : The mechanisms of loosening in total hip arthroplasty (THA) and the role of polyethylene (PE) wear debris in this process is unclear. Radiographic measurements showed that THA with 32 mm heads have about 3 times greater volumetric wear than those with 22 mm heads. LÄS MER

  3. 22. Automatic image analysis for decision support in rheumatoid arthritis and osteoporosis

    Författare :Johan Kälvesten; Anders Persson; Torkel Brismar; Glenn Haugeberg; Claes Lundström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Osteoporosis; rheumatoid arthritis; digital X-ray radiogrammetry; joint space width; bone densitometry;

    Sammanfattning : Low-energy trauma and fragility fractures represent a major public health problem. The societal cost of the fragility fractures that occurred in Sweden 2010 has been estimated at €4 billion.In rheumatoid arthritis (RA), patient outcomes have improved greatly in recent years.

  4. 23. Temporomandibular joint imaging using cone-beam computed tomography

    Författare :Durer Iskanderani; Reinhilde Jacobs; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cone-beam computed tomography (CBCT) is one of the most revolutionary innovations in dentistry, and was introduced into the dental field two decades ago as a three-dimensional (3D) imaging modality. Since then, it has gained general clinical acceptance, and is widespread among many dental specialties. LÄS MER

  5. 24. A prospective chohort study on bone formation and bone loss in ankylosing spondylitis

    Författare :Anna Deminger; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ankylosing spondylitis; bone mineral density; spinal new bone formation; longitudinal cohort study;

    Sammanfattning : Background and objectives: Patients with ankylosing spondylitis (AS) have an increased risk of bone loss with development of osteoporosis and vertebral fractures (VFs) but also spinal new bone formation with growth of bony spurs (syndesmophytes) between the vertebrae. Measurements of spinal bone mineral density (BMD) by the routine method dual-energy x-ray absorptiometry (DXA) in anteroposterior (AP) projection can be difficult to interpret due to the spinal new bone formation.

  7. 25. Functional assessment system of lower-extremity dysfunction

    Författare :Ulrika Öberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The Functional Assessment System (FAS) is a new instrument for evaluation of lower-extremity dysfunction. It consists of 20 variables, representing major lower--extremity functions related to daily life activities. LÄS MER
