4. 3. Late complications after total hip arthroplasty

   Författare :Erik B Mathiesen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The present study concerns late complications after total hip arthroplasty in relation to implant material, design, and mode of implant fixation. Frictional characteristics in retrieved and new acetabular sockets was studied under dry and lubricated conditions comparing conventional polyethylene sockets with polyacetal sockets from the Christiansen prosthesis.

5. 4. Evaluation of methods of measuring wear of polyethylene acetabular components intotal hip arthroplasty

   Författare :Charles R Bragdon; Göteborgs universitet; []
   Nyckelord :Total hip replacement; polyethylene; wear; radiostereometric analysis; radiograph;

   Sammanfattning : Background: The introduction of highly cross-linked, wear resistant polyethylene acetabularcomponents for clinical use in total hip replacements has intensified the interest in and need for highlyaccurate methods of measuring wear from clinical radiographs. There are several methods currentlyavailable for measuring the relative displacement of the femoral head into the acetabular componentresulting from the combination of plastic deformation and wear of the polyethylene bearing surface.

7. 5. Resorbable Bone Cement for Augmentation of Hip Fracture

   Författare :Per Mattsson; Sune Larsson; Nils Dalen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Kirurgi; Surgery; Kirurgi;

   Sammanfattning : Surgical treatment of hip fractures is frequently associated with secondary fracture displacement, in part due to weak osteoporotic bone. So far, improvements have focused on new metal implants although an alternative could be to augment the bone that surrounds the implant. LÄS MER
