  1. 6. Wear and Fixation of the acetabular component : in vivo evaluation of different polyethylenes and modes of fixation in total hip arthroplasty

    Författare :Stephan Maximilian Röhrl; Kjell Gunnar Nilsson; Bo Nivbrant; Lars Nordsletten; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; total hip arthroplasty; acetabular component; wear; fixation; osteolysis; Radiostereometry; RSA; Kirurgi; Surgery; Kirurgi; ortopedi; Orthopaedics;

    Sammanfattning : Polyethylene wear and micromotion of the implant play an important role in multifactorial etiology of osteolysis leading to aseptic loosening of the acetabular components. Despite excellent results in primary total hip arthoplasty in a 10-15 year perspective there are still unsolved problems. LÄS MER

  3. 7. Friction and wear in rolling and sliding contacts

    Författare :Christer Spiegelberg; Sören Andersson; Roland Larsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; friction; wear; rolling and sliding contacts; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Mechanical products are always expected to perform better, last longer, be more environmentally friendly and preferably cost less. Rolling and sliding contacts are found in many mechanical products, and friction and wear in the contacts have a direct impact on the products’ ability to meet these demands. LÄS MER
