    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fixation; Hip prostheses; primary arthroplasty; revision arthroplasty; cemented; uncemented; bone grafting; Fixation; Höftprotes; primärartroplastik; revisionsartroplastik; cement; cementfri; bentransplantation; Orthopaedics; Ortopedi;

    Sammanfattning : This thesis, comprising 5 separate studies, is concerned with fixation of prosthetic components in total hip arthroplasty. The results and conclusions of the studies fol-low;The initial stability of femoral revision components, the long cementless PCA stem and the Exeter standard stem cemented in a bed of impacted bone graft, was com-pared in an experimental study.

  3. 2. Neuromusculoskeletal interfacing of lower limb prostheses

    Författare :Alexander Thesleff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OPRA; bone-anchored attachment; Enhanced Osseointegrated Prostheses for the Rehabilitation of Amputees e-OPRA .; Osseointegration; direct skeletal attachment; neuromusculoskeletal interface; OPRA; Osseointegrated Prostheses for the Rehabilitation of Amputees OPRA ; Enhanced Osseointegrated Prostheses for the Rehabilitation of Amputees e-OPRA .;

    Sammanfattning : The method of bone-anchored attachment of limb prostheses via a percutaneous skeletal extension was developed to circumvent commonly reported problems associated with the conventional method of socket attachment. In addition to the direct structural connection, the percutaneous implant may serve as a conduit for bidirectional communication between muscles and nerves within the residual limb and the prosthesis.

  4. 3. Myoelectric Control for Hand Prostheses

    Författare :Fredrik Sebelius; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mät- och instrumenteringsteknik; Care and help to handicapped; Handikappade; vård och rehabilitering; Instrumentation technology; Virtual; Recognition; Real time; On-line learning; Myoelectric; Hand prosthesis; EMG; ANN; Artificial hands;

    Sammanfattning : An investigation of improvements of myoelectric prostheses has been undertaken. The primary aims of this thesis were (1) to generate an accurate prediction of as many hand movement as possible, (2) to produce a training setup for subjects allowing intuitive and instant control over multiple movements, and (3) to reduce the training cycle for the control system to a maximum of a couple of minutes to enable optimizations, e.

  5. 4. In vitro evaluation of hip prostheses

    Författare :H Lucas Anissian; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aseptic loosening and periprosthetic osteolysis are the most common complications (5-10% in 10 years follow up) after total hip arthroplasty. Polyethylene debris appears to play a major role in this process. LÄS MER

  7. 5. On sensory feedback in hand prostheses

    Författare :Christian Antfolk; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prosthetic hands; sensory feedback.;

    Sammanfattning : Amputation of the hand implies the loss of the ability to grasp and the ability to "feel". The grasping function can be primitively restored using an active prosthesis. Multi­articulating electrically powered hands have recently made their way to the market and these hands provide enhanced grasping and gripping capabilities. LÄS MER
