  1. 16. Physical activity, bone density, and fragility fractures in women

    Författare :Undis Englund; Ulrika Pettersson Kymmer; Peter Nordström; Gustaf Bucht; Karl Obrant; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical activity; bone density; neuromuscular function; fragility fractures; women; Geriatrics and medical gerontology; Geriatrik och medicinsk gerontologi; Geriatrics; geriatrik;

    Sammanfattning : Scandinavia has among the highest incidence of fragility fractures in the world. The reasons for this are unknown, but might involve differences in genetic and/or environmental factors, such as sunlight exposure and levels of physical activity. LÄS MER

  3. 17. Studies on energy expenditure in walking after stroke

    Författare :Anna Danielsson; Göteborgs universitet; []
    Nyckelord :Cerebrovascular accident; Energy expenditure; Rehabilitation; Walking;

    Sammanfattning : After stroke, altered movement pattern involves low walking speed and increased energy cost as compared to normal. Cardiovascular disease is common in the stroke population. Knowledge about the physiological demands of various training interventions is important for the planning of exercise. LÄS MER

  4. 18. Hip revisions with impacted morselized allograft bone and cement. Patient outcome, prosthetic fixation and risks

    Författare :Ewald Ornstein; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiostereometry; NHP; patient outcome; cement; allograft; morselized; impacted; bone transplantation; hip; Arthroplasty; revision; complications; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : 144 consecutive hip revisions performed with morselized allograft bone and cement were followed up to 5 years after surgery. In 49 hips patient outcome was evaluated with the Nottingham Health Profile (NHP) questionnaire and Charnley hip scores in 47 hips prosthetic fixation was evaluated with radiostereometry (RSA)and in all 144 hips risks and complications were recorded using a prspective protocol.

  5. 19. Knee joint laxity and kinematics after anterior cruciate ligament rupture : roentgen stereophotogrammetric and clinical evaluation before and after treatment

    Författare :Håkan Jonsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; Kinematics; Anterior-posterior laxity; Surgery; Roentgen stereophotogrammetric analysis; Muscle strength; Functional tests;

    Sammanfattning : Rupture of the anterior cruciate ligament (ACL) increases anterior-posterior (AP) laxity. The treatment aims to reduce or teach the patient to control this instability. Altered kinematics due to absent ligament function may result in knee arthrosis. This study evaluated the clinical and functional results of reconstructive surgery. LÄS MER

  7. 20. Kinematics and fixation of total knee arthroplasties : a clinical, radiographic, scintimetric, and roentgen stereophotogrammetric evaluation

    Författare :Kjell G. Nilsson; Johan Kärrholm; Leif Ryd; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total knee arthroplasty; tibial component; kinematics; micromotion; loosening; scintimetry; roentgen stereophotogrammetric analysis;

    Sammanfattning : Aseptic loosening of the tibial component is an important cause of failure after total knee arthroplasty. Bone destruction often claimed to be caused by the cement makes the revision difficult. In order to treat younger patients, uncemented fixation has been introduced, but the etiology to loosening is multifactorial and only partly known. LÄS MER
