The spinal implant may include top beams and bottom beams separated by at least one post that is, in one embodiment, length variable in response to a load put on the implant after deployment of the implant. In an alternate embodiment, at least one post is laterally variable in response to a load put on the implant. In another embodiment, one of the posts may be centrally located.
