Abstract
An interbody device that restores the disc space height between two vertebrae during spinal fusion surgery. The device includes a center plate surrounded by a perimeter portion that combine to have a relatively flat configuration in one dimension and relatively wide configuration in a perpendicular dimension. After the disc space has been cleared, the device is inserted into the disc space in a direction so that the wide dimension of the device is substantially parallel to the body of the vertebrae. The device is then rotated so that the wide dimension of the device becomes perpendicular to the vertebral body so as to cause the disc space height to be restored. Bone graft material is then introduced through a fill tube coupled to the device so that the bone graft material is distributed on both sides of the center plate and into the disc space.
