    • A trial system for an implantable joint replacement includes a guide assembly having a baseplate and a guide plate, the guide plate translatable relative to the base plate along a straight path while directly connected to the baseplate. A first adjustment mechanism may selectively control the translational juxtaposition of the guide plate relative to the baseplate. The guide plate may further be rotatable relative to the baseplate around a rotation axis. A second adjustment mechanism may selectively control the rotational juxtaposition of the guide plate relative to the baseplate, and can lock the plates together. The rotation axis may be medially offset from the center of the guide assembly. The guide plate provides in situ positionable cutting guidance for implantation of prosthetic joint components. The system may further include an articulating insert trial to determine preferred joint alignment, implantable insert configuration and/or positioning of the guide plate.
    • 一种用于植入式关节置换物的试验系统包括具有底板和导板的导向组件,导板可以沿直线路径相对于底板平移,同时直接连接到底板。 第一调节机构可以选择性地控制导板相对于底板的平移并置。 导板还可以围绕旋转轴线相对于底板旋转。 第二调节机构可以选择性地控制导板相对于底板的旋转并置,并且可以将板锁定在一起。 旋转轴线可以从引导组件的中心向内侧偏移。 导板提供用于植入假体关节部件的原位定位切割引导。 该系统可以进一步包括关节式插入件试验以确定优选的关节对准,植入式插入件构造和/或导板的定位。
