A spinal cage assembly has an inner sleeve-shaped tubular body which telescopes into or through an outer tubular sleeve-shaped body from either a first or second end thereof. Each inner and outer sleeve is made of one-piece construction made of a physiologically compatible metal. Both sleeve-shaped bodies have multiple holes therein and can be secured at different heights relative to one another. At least one of the sleeve-shaped bodies has two edges which form a different angle of between about 3° and about 6° with respect to the transverse axis of the sleeve-shaped bodies. An edge having a different angle is exposed depending on which end of the inner body is inserted into or through the outer body.
