    摘要： The invention is a modular interbody fusion device for fusing adjacent spinal vertebrae that is adapted to be implanted in a prepared interbody space including a first modular segment having a width including a first rail extending at least partially along one side of the width and beyond a periphery of a body portion of the first modular segment, a second modular segment having a width and slidably connected to the first rail on one side of the width and having a second rail extending at least partially along another side of the width and beyond a periphery of a body portion of the second modular segment, a third modular segment having a width and slidably connected to the second rail on one side of the width and wherein the device has an expanded position in which the second and third modular segments are extended along the first and second rails and positioned in a generally end to end configuration spaced apart by the rails prior to implantation and an implanted position in which the modular segments are positioned in a generally side by side configuration that defines a unitary body that mimics the planar shape of the vertebra such that the device contacts and supports the adjacent vertebra.

    摘要翻译： 本发明是一种用于融合相邻脊椎椎体的模块化体内融合装置，其适于植入准备的体间空间中，所述椎间体空间包括具有宽度的第一模块化区段，所述第一模块区段至少部分地沿着所述宽度的一侧延伸并超出外围 所述第一模块化部分的主体部分具有宽度并且在所述宽度的一侧上可滑动地连接到所述第一轨道的第二模块化区段，并且具有至少部分地沿着所述宽度的另一侧延伸并且超过所述宽度的外围的第二轨道 所述第二模块化区段的主体部分，具有宽度的第三模块区段，并且在所述宽度的一侧上可滑动地连接到所述第二轨道，并且其中所述设备具有扩展位置，其中所述第二和第三模块化区段沿着所述第一 和第二轨道，并且在植入之前定位成由轨道间隔开的大致端对端构型和植入位置 他的模块化部分以大致并排配置的方式定位，其限定了模仿椎骨的平面形状的整体，使得该装置接触并支撑相邻的椎骨。
