Friction and Wear of Artificial Joints: A Historical Reviewugh problems of friction and wear related to the total hip system were widely discussed as far back as the early 1960s. Since then, devices with polyethylene, especially ultra-high-molecular-weight polyethylene, on metal or alumina in the total hip system (such as the Charnley type), have been the i作者: misshapen 時間: 2025-3-22 14:39
Matrix Degradation in Osteoclastic Bone Resorption Under Pathological Conditionstrix degradation by proteinases. Activated osteoclasts attach to only mineralized bone matrix through binding of their αvβ3 integrin to the Arg-Gly-Asp sequence of osteopontin in the matrix, and then form a tightly sealed subosteoclastic compartment.

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作者: 詞匯表 時間: 2025-3-24 08:51
