摘要：
Prosthetic artificial joints are described, including hip, knee and shoulder joints. In some embodiments, an artificial joint prosthesis includes: a bone-facing surface of an artificial joint prosthesis, the bone-facing surface configured to face a bone-prosthesis interface in vivo; a first component of the artificial joint prosthesis including a contact surface of the artificial joint prosthesis, the first component fabricated from at least one polymer and a plurality of magnetic particles; and a second component of the artificial joint prosthesis including at least one magnet configured to create a magnetic field within the artificial joint, the at least one magnet positioned to form a magnetic field directed to influence a location of debris including the magnetic particles in the joint to a position distinct from the bone-prosthesis interface in vivo .
摘要（中）：
描述了假肢人工关节，包括髋关节，膝关节和肩关节。 在一些实施例中，人造关节假体包括：人造关节假体的面向骨的表面，所述面向骨的表面构造成在体内面向骨假体界面; 所述人造关节假体的第一部件包括所述人造关节假体的接触表面，所述第一部件由至少一个聚合物和多个磁性颗粒制成; 以及所述人造关节假体的第二部件，所述第二部件包括构造成在所述人造关节内产生磁场的至少一个磁体，所述至少一个磁体定位成形成用于影响所述关节中包括所述磁性颗粒的碎屑位置的磁场 到与体内骨假体界面不同的位置。
