    • The present disclosure provides a provisional tibial prosthesis system for a set of prosthetic knee joints for implantation in a natural knee, the provisional tibial prosthesis system including a bearing component and a bearing support, the spacing of the bearing component from the bearing support is adjustable to allow for representation of a variety of different sized final tibial prostheses. In this system, only one provisional bearing component corresponding to each level of constraint is needed and shims are used to adjust the spacing of the bearing component from the bearing support. The shims are slidably insertable between the bearing component and the bearing support in an anterior/posterior direction to allow for adjustment of the spacing of the bearing component from the bearing support. The number of provisional components needed during knee surgery is reduced and adjustment of the system only requires the knee joint to be distracted by a distance equal to the height of a particular shim.
    • 本公开提供了一种临时胫骨假体系统,用于一组用于植入自然膝部的假膝关节,临时胫骨假体系统包括轴承部件和轴承支撑件,轴承部件与轴承支撑件的间隔可调节到 允许表示各种不同大小的最终胫骨假体。 在该系统中,仅需要对应于每个约束级别的一个临时轴承部件,并且使用垫片来调节轴承部件与轴承支撑件的间距。 垫片在前/后方向上可滑动地插入在轴承部件和轴承支撑件之间,以允许轴承部件与轴承支撑件的间隔的调整。 在膝关节手术期间需要的临时部件的数量减少,并且系统的调整仅需要将膝关节分心等于特定垫片的高度。
