  1. 1. Osteoarthritis of the Hip and Uncemented Total Hip Arthroplasty : Effects of Immediate Weight Bearing on Implant Stability, Bone Mineral Density, and Body Composition

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis of the hip; uncemented; total hip arthroplasty; stability; RSA; BMD; DXA; body composition; weight bearing; Orthopaedics; Ortopedi; Orthopaedics; Ortopedi;

    Sammanfattning : The initial recommendation for the postoperative regime after uncemented total hip arthroplasty (THA) was 6-12 weeks of partial weight bearing (PWB) to obtain a stable implant position during bone ingrowth. In recent years patients with uncemented THA have increasingly practiced full weight bearing (FWB) after surgery, which has largely been based on clinical experience rather than on scientific evidence.

  3. 2. Uncemented Total Hip Arthroplasty : Aspects on Bone Biology, Implant Fixation, Periprosthetic Bone Remodeling, Bone Mineral Density and Effects of Denosumab

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; THA; F-PET; Denosumab; CTMA;

    Sammanfattning : Uncemented total hip arthroplasty (THA) is associated with loss of periprosthetic bone mineral density (BMD). The collum femoris preserving (CFP) stem lost 28% of proximal BMD at 2 years. LÄS MER

  4. 3. On Fixation of Hip Prostheses

    Författare :Lars Palm; Ingemar Ivarsson; Ola Wahlström; Jan Milbrink; Linköpings universitet; []
    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.

  5. 4. 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.

  7. 5. Form and Finish of Implants in Uncemented Hip Arthroplasty : Effects of Different Shapes and Surface Treatments on Implant Stability

    Författare :Stergios Lazarinis; Nils P. Hailer; Lars Weidenhielm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Form; Finish; Total hip arthroplasty; Swedish Hip Arthroplasty Register; Hydroxyapatite; RSA; DXA; BMD; Stability.; Orthopaedics; Ortopedi;

    Sammanfattning : The design of an uncemented hip arthroplasty implant affects its long-term survival. Characteristics such as the form and the finish of the implant are crucial in order to achieve the best possible conditions for long-term implant survival. LÄS MER
