Abstract

A fusion implant for insertion between opposing vertebrae includes a body having an inner surface defining a hollow inner chamber for containing a graft material therein. The body includes a stress transfer mechanism for transferring stress from the vertebrae surrounding the implant to the graft material contained within the implant. A method is provided for implanting the fusion implant between opposing vertebrae by the steps of inserting an implant into a collapsed disc space between adjacent vertebrae, the implant including a collapsed body, and expanding the body to spread the adjacent vertebrae apart.
