Abstract
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 adj…
