1. 1. Clinical and experimental studies on wear and osteolysis in total joint replacement

   Författare :Thord von Schewelov; Ortopedi - klinisk och molekylär osteoporosforskning; []

   Sammanfattning : Total hip arthroplasty is a very successful procedure. Despite this fact, however, a certain portion of patients has to be revised. One major reason for revision is the wear of the polyethylene leading to loosening and osteolysis. LÄS MER

3. 2. 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.

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. On late complications with HA coated hip arthroplasties

   Författare :Magne Røkkum; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hip arthroplasty; hydroxyapatite; wear; osteolysis; loosening; clinical; radiological and histological examination;

   Sammanfattning : 100 hips in 86 patients were operated with a total hip arthroplasty entirely coated with a 155±35 µm thick HA coating, and included in a clinical and radiological follow-up study. The female/male ratio was 75/25, and the mean age was 56 years (32-73). Early clinical results were excellent, especially pain relief. No thigh pain was found. LÄS MER

7. 5. Assessment using computed tomography of wear and osteolysis in uncemented cups

   Författare :Buster Sandgren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Total Hip Arthroplasty;

   Sammanfattning : Introduction: Uncemented acetabular cups are widely used since the early 1990’s, particularly on younger patients with osteoarthritis. Patients with these cups have a reported high risk for revision in the Swedish Hip Arthroplasty Register (SHAR) due to wear and periacetabular osteolysis (PAO). LÄS MER
