  1. 1. Computed Tomography of Acetabular Cup Wear and Effect of Surface Roughness on Wear and Oxidation of UHMWPE Hip Prostheses

    Författare :Anneli Jedenmalm; Ulf Gedde; André Stark; Karin Jacobson; Nicklas Axén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip prostheses; Computed Tomography; Surface roughness; UHMWPE; Wear; Coating; Gamma-irradiation; pin-on-disc; hip simulator; Medical engineering; Medicinsk teknik;

    Sammanfattning : Aseptic loosening is the most common complication in total hip replacement (5- 10% at 10 years follow up). The magnitude of the problem is illustrated by the fact that about one million hip prostheses are implanted worldwide each year. LÄS MER

  3. 2. The Uncemented Cup in Total Hip Arthroplasty : stability, Wear and Osteolysis

    Författare :Volker T C Otten; Sead Crnalic; Kjell G Nilsson; André Stark; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Artificial hip joint replacement has undergone tremendous development in the past 100 years. In the beginning, complications, such as infection and early loosening, were the rule rather than the exception. Today, complications of any sort are rare during the first decade after the operation.

  4. 3. Bone Development and the Nervous System

    Författare :Gregor Sisask; Olof Nilsson; Anders Bjurholm; Kenneth B Jonsson; André Stark; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Cellbiologi;

    Sammanfattning : Innervation of bone influence bone modeling, growth and remodeling. Pro-inflammatory cytokines released after tissue trauma are recognized as neurotrophic factors as well as factors influencing bone formation. The Wnt signaling pathway, essential for cell migration during embryogenesis is found to influence bone formation during fracture healing. LÄS MER

  5. 4. Pressure ulcers - role of the nurse to improve patient safety : prevalence, risk factors, classification and documentation in patients undergoing hip surgery

    Författare :Eila Sterner; Bjöörn Fossum; Christina Lindholm; André Stark; Ewa Idwall; Sophiahemmet Högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hip fracture; Pressure ulcers; Classification; Reflectance spectrophotometer; Nursing documentation;

    Sammanfattning : Pressure ulcer is a common complication in hip fracture surgery and convalescence. Earlier prevalence studies have demonstrated a lower prevalence in Southern Europe than in Northern Europe. LÄS MER

  7. 5. Hand grip strength and postural control among individuals with and without Chronic Obstructive Pulmonary Disease : Epidemiological and motion laboratory studies

    Författare :Viktor Strandkvist; Ulrik Röijezon; Anne Lindberg; Caroline Stridsman; Agneta Larsson; André Nyberg; Luleå tekniska universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysioterapi; Physiotherapy;

    Sammanfattning : BackgroundChronic obstructive pulmonary disease (COPD) is estimated to affect approximately 8%–10% of all adults. The disease is considered to be a heterogenic syndrome with systemic effects, in which comorbidities including cardiovascular diseases, muscle dysfunction and fatigue are common. LÄS MER
