Dynamic Viscoelasticity of Ultrahigh-Molecular-Weight Polyethylene After Ethylene Oxide Gas or Gamma unsterilized, 2.5 Mrad gamma-irradiation sterilized in air, and ethylene oxide gas (EOG)-sterilized. The dynamic viscoelastic measurement was conducted over a temperature range of —150°C to 350°C using a dynamic mechanical spectrometer in tensile mode on a sample at an amplitude of 10 ltm, at a frecompel 发表于 2025-3-23 23:46:43

Methods to Reduce the Wear of Ultrahigh-Molecular-Weight Polyethyleneweight polyethylene (UHMWPE). To reduce the wear of UHMWPE, choice of counterface and improvement of UHMWPE itself appear to be two likely venues for exploration. First, the wear of UHMWPE against various disks was examined by a pin-on-disk device. As a result, it was shown that wear factor decrease词汇表 发表于 2025-3-24 08:51:52
Wear, Friction, and Mechanical Investigation and Development of Alumina-to-Alumina Combination Totalnical successes have been achieved. However, there are also many cases in which the excessive wear of particles of polyethylene can result in late aseptic loosening. To solve the critical issues resulting from polyethylene wear, a new all-alumina hip joint was developed by considering the design fro莎草 发表于 2025-3-24 12:53:22

Total Hip Arthroplasty with Hydroxyapatite-Coated Prosthesesnd clinical success. The quality and quantity of the coating is sensitive to application techniques, metal substrate, and manufacturing controls—all important in creating a clinically successful coating. Bioactive coatings other than hydroxyapatite have had mixed success and are generally not availa
