Abstract

An intervertebral fusion cage for insertion between two adjacent, opposing vertebrae, wherein the fusion cage is constructed in a way that stress absorbed by the cage is transferred to the graft material in the hollow inner cavity, thus allowing ideal strain levels to be attained in the graft material under minimal loads, while also offering a level of protection to the graft material preventing mechanical failure of the graft material due to high strains.
