An intervertebral fusion device is formed of an elastic block body which is provided in the upper contact surface thereof with a plurality of downward elastic slots substantially parallel to one another, and in the lower contact surface thereof with one or more upward elastic slots substantially parallel to the downward elastic slots. The upward elastic slots and the downward elastic slots are arranged in an alternating manner. The elastic block body has a left surface and a right surface, which are substantially planar in construction. The upper contact surface and the lower contact surface of the elastic block body are of a convex construction.
