  1. 21. Traumatic patellar dislocation in children : epidemiology, risk factors, the MPFL and treatment outcome

    Författare :Marie Askenberger; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The knee joint is one of the most common injury sites in children, with the spectrum of injuries differing from those in adults. Traumatic lateral patellar dislocation (LPD) is the most common serious injury; the incidence is approximately 1/1000 in children 9-15 years of age. The risk for recurrent dislocation is high in this age group. LÄS MER

  3. 22. Norrbottnian congenital insensitivity to pain

    Författare :Jan Minde; Göran Toolanen; Li Tsai-Fällender; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pain insensitivity; HSAN; Orthopaedics; Ortopedi;

    Sammanfattning : Congenital insensitivity to pain is a rare hereditary neuropathy. We present patients from a large family in Norrbotten, Sweden with a mutation in the nerve growth factor β gene (NGFß). Using a model of recessive inheritance, we identified an 8.3-Mb region on chromosome 1p11. LÄS MER

  4. 23. Arthroscopy in the upper extremity

    Författare :Lars Adolfsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This stndy comprising six separate papers, is concerned with the techniques of, and bevaluation of arthroscopy as a diagnostic and therapeutic tool in different pathologic conditions in the upper extremity.Arthroscopy proved to increase diagnostic accuracy in 177 examined patients with anterior shoulder instability or shoulder pain.

  5. 24. Improving Machining System Performance through designed-in Damping : Modelling, Analysis and Design Solutions

    Författare :Lorenzo Daghini; Cornel Mihai Nicolescu; Miroslav Píška; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining performance; Cutting stability; Passive damping; High Damping Interface; Boring bar; Turret; SRA - Production; SRA - Produktion;

    Sammanfattning : With advances in material technology, allowing, for instance, engines to withstand higher combustion pressure and consequently improving performance, comes challenges to productivity. These materials are, in fact, more difficult to machine with regards to tool wear and especially machine tool stability. LÄS MER

  7. 25. 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
