Early Cementing Does Not Increase Toughness of Grit Blasted Interfaces
Introduction: Grit blasted stem-cement interfaces have been advocated as a means of increasing the bond strength of the stem-cement interface in cemented total hip arthroplasty. Recent work has suggested that early cementing of rough stem surfaces can increase the bond strength of the interface when compared to the same interface cemented using very doughy cement [1]. Based on these findings, s...
متن کاملSurvival analysis of cementless grit-blasted titanium total hip arthroplasties.
Although about 200000 cementless Zweymüller-Alloclassic total hip arthroplasties (THAs) were carried out worldwide in the last decade, the survival analysis of these prostheses was not available in the 2000 report of the Swedish national hip arthroplasty registry. We report a prospective survivorship analysis of 200 consecutive grit-blasted cementless Alloclassic primary THAs carried out since ...
متن کاملNew Surface Treatment to Reduce Alumina Coverage of Grit-blasted Implants
INTRODUCTION For more than 20 years alumina-blasted surfaces have been successfully used for cementless surgical implants, because of their good biocompatibility and rapid osseointegration. However, it has been shown recently that grit-blasting leads to partial embedding of aluminum oxide particles that can cover 24% to 40% of the surface, with a difference between manufacturers [1-2]. These pa...
متن کاملAcid Etching and Plasma Sterilization Fail to Improve Osseointegration of Grit Blasted Titanium Implants
Interaction between implant surface and surrounding bone influences implant fixation. We attempted to improve the bone-implant interaction by 1) adding surface micro scale topography by acid etching, and 2) removing surface-adherent pro-inflammatory agents by plasma cleaning. Implant fixation was evaluated by implant osseointegration and biomechanical fixation.The study consisted of two paired ...
متن کاملHydroxyapatite-coated versus grit-blasted femoral stems. a prospective, randomised study using EBRA-FCA.
We have carried out a prospective, randomised study designed to compare the long-term stability of the stem of cementless femoral implants with differing surface configurations. A total of 50 hips (46 patients) was randomised into two groups, according to whether the medullary stem had been grit blasted (GB) or coated with hydroxyapatite (HA). Both femoral prostheses were of the same geometrica...
