  2. 1. Functional properties of silicon nitride based materials for joint applications

    Author : Luimar N. Corrêa Filho; Cecilia Persson; Julia Shelton; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon nitride; Coatings; Wear; Joint replacements; HiPIMS; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Total hip and total knee replacements are generally successful procedures for patients suffering with pain due to bone fracture or diseases affecting the joints. However, the materials that are commonly used still have limitations. In particular, corrosion products and wear debris may give rise to negative body reactions. READ MORE

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

    Author : Johanna Olofsson; Staffan Jacobson; Håkan Engqvist; Koshi Adachi; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Silicon nitride for total hip replacements

    Author : Maria Pettersson; Cecilia Persson; Håkan Engqvist; Staffan Jacobson; Kenneth Holmberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SiNx; Si3N4; coatings; CoCr; Ti; alloy; tribology; wear; corrosion; dissolution; debris; hip; arthroplasty; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : For more than 50 years total hip replacements have been a common and successful procedure to increase patient mobility and quality of life. The 10-year implant survival rate is 97.8%. READ MORE

  6. 4. Elbow kinematics : studies of the elbow joint under normal conditions and after joint replacement

    Author : Anne Ericson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Total elbow arthroplasty (TEA) is used for treatment of patients with severe pain and disability due to reumatoid arthritis. Long term results are not as good as for hip and knee replacements. READ MORE

  7. 5. Knee joint kinematics and the effects of arthropasty component design

    Author : Tuuli Saari; Göteborgs universitet; []
    Keywords : Total knee replacement; motion analysis; radiostereometry; migration; kinematics; radiolucent lines; clinical outcome;

    Abstract : Aims: To evaluate the influence of medial osteoarthritis on knee joint kinematics and the effect of design in total knee replacements (TKR) on the kinematics of trunk, hip, knee and ankle. Associations between articulating surface design, clinical outcome and fixation of the tibial component were also evaluated. READ MORE
