  1. 1. ON ARTHRODESIS AND REPLACEMENT OF THE HUMAN ANKLE

    Författare :Thomas Anderson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis; Replacement; Surgery; orthopaedics; traumatology; traumatologi; Kirurgi; ortopedi; Rheumatoid arthritis; Arthrodesis; Ankle;

    Sammanfattning : Of 30 primary ankle fusions in patients with osteoarthrosis, 25 ankles underwent clinical evaluation by two independent observers. In 29 cases, two independent radiologists, unanimously found 26 ankles to be radiographically fused, and three not fused. The consistency between the two orthopaedic surgeons evaluations was somewhat lower. LÄS MER

  3. 2. The fixation of joint prostheses. Aspects on mechanics and biology

    Författare :Ulrik Hansson; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiostereometry; histology; interface; micromotion; knee; joint replacement;

    Sammanfattning : Abstract: In the interface, between implant and bone or between the cement and bone, there will develop some amount of fibrous tissue. The synovial fluid, the synovium, the cartilage and the subchondral bone from the non-replaced knee compartment that had been exposed to wear particles were studied by histological analyses. LÄS MER

  4. 3. Finger Joint Reconstruction with Rib Perichondrium

    Författare :Daniel Muder; Torbjörn Vedung; Nils Hailer; Ola Nilsson; Simon Farnebo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; finger joint; reconstruction; cartilage; transplantation; osteoarthritis; Orthopaedics; Ortopedi;

    Sammanfattning : Difficulties in repairing and reconstructing articular cartilage damaged by trauma or disease remain unsolved and are one of the major challenges confronting orthopedic and hand surgeons in their clinical work. Relevant research has not adequately described the long-term clinical results, nor has it made a direct comparison to implant surgery after finger joint reconstruction with rib perichondrium.

  5. 4. Friction and Wear Mechanisms of Ceramic Surfaces : With Applications to Micro Motors and Hip Joint Replacements

    Författare :Johanna Olofsson; Staffan Jacobson; Håkan Engqvist; Koshi Adachi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Ceramic; Tribofilm; Alumina; Silicon nitride; Ultrasonic Motors; Hip Joint Replacement; PVD coating; Materials science; Teknisk materialvetenskap; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Surfaces exposed to wear always transform and typically a layer of new structure and composition is formed. This layer, often called tribofilm, changes the friction and wear properties. LÄS MER

  7. 5. Hormone replacement therapy in rheumatoid arthritis

    Författare :Helena Forsblad d'Elia; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; randomised controlled trials; hormone replacement therapy; estrogen; osteoporosis; bone mineral density; bone remodelling; cartilage remodelling; cytokines; insulin-like growth factor 1;

    Sammanfattning : Rheumatoid arthritis (RA) is 2-3 times more frequent in women as compared to men. The peak incidence in women coincides with the years around the menopause and the course of RA is also influenced by events associated with hormonal alterations. LÄS MER
