A bone infusion apparatus for interbody grafts includes a container； a retainer, the retainer including a recess for receiving therein bone graft material； and a lid including a plunger assembly. A method of preparing bone including cadaver bone for use in cervical fusion includes: placing cadaver bone combined with bone collected from a patient into a recess of the retainer； placing the retainer in the container； filling the container with a liquid； attaching a lid the container； depressing a plunger of the lid such that a press head advances toward the retainer causing a dynamic pressure to act on the cadaver bone combined with the bone collected from the patient； suctioning the liquid from the container； removing the combined bone from the retainer； and placing the combined bone removed from the container into a vertebral interspace of the patient.
