2. 1. Wear and Fixation of the acetabular component : in vivo evaluation of different polyethylenes and modes of fixation in total hip arthroplasty

   Author : Stephan Maximilian Röhrl; Kjell Gunnar Nilsson; Bo Nivbrant; Lars Nordsletten; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; total hip arthroplasty; acetabular component; wear; fixation; osteolysis; Radiostereometry; RSA; Kirurgi; Surgery; Kirurgi; ortopedi; Orthopaedics;

   Abstract : 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. READ MORE

4. 2. Fixation of the cemented acetabular component in hip arthroplasty

   Author : Gunnar Flivik; Lund Ortopedi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; reumatologi; Surgery; Skelett; muscle system; rheumatology locomotion; Skeleton; Cement pressurization; Cement penetration; Acetabulum; Cancellous bone; muskelsystem; Total hip arthroplasty; RSA;

   Abstract : In total hip arthroplasty cemented fixation of the acetabular component is a generally successful concept, but the rate of aseptic loosening and consequent revision surgery is still too high. One of the crucial factors for longterm implant survival is the initial fixation and stability. READ MORE

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

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

   Abstract : 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. READ MORE

6. 4. Pelvic Ring Injuries and Acetabular Fractures : Quality of Life Following Surgical Treatment

   Author : Tomas Borg; Sune Larsson; Hans Granhed; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Orthopaedics; Ortopedi; Orthopaedics; Ortopedi;

   Abstract : The overall aim was to study outcome following surgery of the injured pelvis with focus on assessment from the patient’s perspective. All adult patients operatively treated for pelvic ring injuries or acetabular fractures at the Department of Orthopaedics, Uppsala University, starting 2003 were prospectively included and followed with quality of life (QoL) instruments for 2 years.

7. 5. Assessment of acetabular cup position with computed tomography

   Author : Henrik Olivecrona; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : 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. READ MORE
