    • A cervical bone plate includes a graft window that allows access to and/or visualization of a bone graft area of the cervical spine after attachment of the present cervical plate to the vertebrae. The window is preferably, but not necessarily, sized for maximum exposure of the graft area and/or the vertebral body without compromising plate strength, particularly with respect to federal standards for such devices. The window is centrally positioned on the plate and is sized to provide alignment of the plate onto the vertebrae at the base of the vertebra fastener or screw holes of the plate. In a dynamic form of this cervical bone plate, the graft window expands and contracts with respective expansion and contraction of the dynamic plate after attachment to the vertebrae (i.e. "dynamizes"). In another form, a three­component dynamic bone plate is configured such that a middle component accepts an identical end component at both ends of the middle component. The end component is a 180° interchangeable part. The middle component and the end component have cooperating configurations and complementarily configured grooves that allow sliding movement between the middle component and the end components. A two-pillar construction provides a central window.
    • 颈椎骨板包括移植物窗口,该移植物窗口允许在将当前颈盘附接到椎骨后接近和/或可视化颈椎的骨移植物区域。 该窗口优选但不是必须地确定尺寸,以使得移植物区域和/或椎体的最大暴露不会影响板强度,特别是关于这种设备的联邦标准。 窗口位于板的中心位置,其大小设置为将板对准椎骨紧固件底部或板的螺钉孔处的椎骨。 在该颈椎骨板的动态形式中,移植窗在附着于椎骨后(即“动态化”)随着动态板的相应膨胀和收缩而膨胀和收缩。 在另一种形式中,构造一个三sh组件动态骨板,使得中间组件在中间组件的两端接受相同的端部组件。 最终组件是180°; 可互换的部分。 中间部件和端部部件具有配合结构和互补配置的凹槽,其允许中间部件和端部部件之间的滑动运动。 双柱结构提供了一个中央窗口。
