  1. 1. Radiographic assessment of cup migration and wear after hip replacement

    Författare :Thomas Ilchmann; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; measurement; assessment; loosening; migration; wear; cup; Hip; arthroplasty; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Methods are needed for accurate measurement of acetabular cup migration and wear after hip replacement. The EBRA (Ein Bild Röntgen Analyse) method was recently introduced as a computerized method for radiographic assessment of acetabular cup migration. LÄS MER

  3. 2. Assessment of acetabular cup position with computed tomography

    Författare :Henrik Olivecrona; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Revision of Total Hip Arthroplasty (THA) due to loosening is necessary in many patients. Diagnosis is usually late with significant bone and soft tissue destruction. Available diagnostic techniques are either not sensitive enough or too complicated and expensive for routine use. LÄS MER

  4. 3. 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

  5. 4. Acetabular Revisions. Risk Factors and Prediction of Re-revision

    Författare :Maziar Mohaddes; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis; Hip; Register studies; Radiostereometry; Acetabular revision; Trabecular metal;

    Sammanfattning : Hip replacement is a successful intervention when treating patients with hip osteoarthritis. Approximately 10% of all patients undergoing primary hip replacement surgery require further surgical interventions (revisions) during their lifetime. Acetabular component (cup) failure is the most common reason for a revision. LÄS MER

  7. 5. Leg length discrepancy and femoral offset after total hip arthroplasty : clinical and radiological studies

    Författare :Sarwar Mahmood; Arkan Sayed-Noor; Sead Crnalic; Gösta Ullmark; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total hip arthroplasty; leg flength discrepancy; femoral offset; WOMAC; quality of life; complication; radiographic measurements; acetabular cup; inclination; anteversion; Orthopaedics; ortopedi;

    Sammanfattning : Every year, about 1 million patients worldwide and 16000 patients in Sweden undergo total hip arthroplasty (THA). This surgical intervention is considered a successful, safe and cost-effective procedure to regain pain-free mobility and restore hip joint function in patients suffering from severe hip joint disease or trauma.
