  1. 11. New polymer materials in total hip arthroplasty. Evaluation with radiostereometry, bone densitometry, radiography and clinical parameters

    Författare :Georgios Digas; Göteborgs universitet; []
    Nyckelord :Total hip arthroplasty; polyethylene; bone cement; wear; fixation; and radiostereometry.;

    Sammanfattning : Aims: To evaluate the outcome of different types of polyethylene, bone cements and one design of uncemented fixation with porous and ceramic coating using radiostereometry, bone densitometry, conventional radiography and clinical parameters.Materials and methods: Study 1: 201 patients were extracted from 5 prospective randomised studies to evaluate femoral head penetration at two years with radiostereometry in four basic designs, cemented Lubinus and Reflection cups, uncemented Trilogy and Reflection cups.

  3. 12. Uncemented hip arthroplasty in primary and revision surgery : patterns of bone remodelling and options to influence periprosthetic bone loss

    Författare :Mats Salemyr; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: The incidence of hip arthroplasty surgery in young and active patients is increasing. Consequently, an increasing number of patients will live with hip prostheses for longer periods of time in the future. LÄS MER

  4. 13. Gait and motion analysis of hip arthroplasty. Validity, reliability and longterm results

    Författare :Roland Zügner; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gait analysis; Hip arthroplasty; Kinematics; Radiostereometric analysis; Hip osteoarthritis;

    Sammanfattning : Introduction: Walking is one of the most fundamental activities of daily living in humans, when the hip joints transfer power between the lower extremities and the pelvis. Hip osteoarthritis (OA) will more or less influence this function and is increasing in an ageing population. LÄS MER

  5. 14. Dislocation of hip arthroplasty in patients with femoral neck fractures

    Författare :Anders Enocson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Femoral neck fractures; Hip arthroplasty; Surgical treatment; Hip dislocations; Cognitive disorders; Quality of life; EQ-5D;

    Sammanfattning : Treatment of displaced fractures of the femoral neck with a hemiarthroplasty (HA) or a total hip arthroplasty (THA) today constitutes standard procedures with a good and predictable outcome with regard to the need for revision surgery, hip function and the health-related quality of life (HRQoL). However, dislocation of the prosthesis remains a substantial clinical problem in this patient group and the dislocation rate is considerably higher than what can be expected following a THA in patients with osteoarthritis.
