    • An orthopedic prosthesis, system and method has a dual bearing component that, along with first and second bone anchoring components, provides multi-axial movement separately with respect to both the first and second bone anchoring components. An ankle prosthesis, system and method may thus be fashioned utilizing these principles that includes a dual bearing component, a tibial component adapted for attachment to the tibia bone, and a talar component adapted for attachment to the talus or calceneus bone of the foot. The dual bearing component includes a superior bearing providing gliding articulation/translation between it and the tibial component, and an inferior bearing providing gliding articulation/translation between it and the talar component. A bearing component plate provides a base or foundation for the superior and inferior bearings. The superior bearing is bonded to the bearing component plate while the inferior bearing moves with respect to the bearing component plate.
    • 矫形假体,系统和方法具有双轴承部件,其与第一和第二骨锚固部件一起提供相对于第一和第二骨锚固部件分开的多轴向运动。 因此,可以利用包括双轴承部件,适于附接到胫骨的胫骨部件和适于附接到脚的距骨或骨质骨的距骨部件的这些原理来制造踝假体,系统和方法。 双轴承组件包括提供其与胫骨部件之间的滑动关节/平移的优异轴承,以及在其与轴向部件之间提供滑动铰接/平移的下轴承。 轴承部件板为上下轴承提供基座或底座。 下轴承相对于轴承部件板移动时,上轴承与轴承部件板接合。
