Does early micromotion of femoral stem prostheses matter? 4-7-year stereoradiographic follow-up of 84 cemented prostheses
TL;DR: Roentgen stereophotogrammetry was used to measure the migration of the centre of the femoral head in 84 cemented Lubinus SP I hip arthroplasties and found these implants showed greater subsidence, medial migration and posterior migration during the first two postoperative years than did the hips which had not been revised.
Journal ArticleDOI

TL;DR: The goals of the study were to quantify the future number of infections at the site of arthroplasties done in the United States, and to investigate the implications for a growing incidence of infections, coupled with accelerating demand forArthroplasty.
Journal ArticleDOI
Guidelines for standardization of radiostereometry (RSA) of implants
TL;DR: 6 research centers have agreed upon standards for terminology, description and use of RSA arrangement including radiographic set-up and techniques, which will form the basis of a detailed standardization protocol under supervision of ISO and the European Standards Working Group on Joint Replacement Implants.
Journal ArticleDOI
Uncemented and cemented primary total hip arthroplasty in the Swedish Hip Arthroplasty Register
TL;DR: Survival of uncemented THA is inferior to that of cemented THA, and this appears to be mainly related to poorer performance of unCEmented cups.
Journal ArticleDOI
Radiostereometry of hip prostheses. Review of methodology and clinical results.
TL;DR: Measurements of implant micromovement during 1 to 2 years after surgery have proved to be of value to predict later clinical failure because of aseptic loosening and revision.
