An intervertebral fusion device, a method of making the intervertebral fusion device, and a method of using the intervertebral fusion device to promote fusion between two consecutive vertebrae in a patient is described. The intervertebral fusion device has an intervertebral fusion cage that has a load bearing wall, and a porous matrix adjacent to the load bearing wall. The load bearing wall of the fusion cage has a greater density than the internal porous matrix. The open pores of the porous matrix define an inner surface to which one or more agents that promote bone growth are attached.
