Abstract
An expanding, conforming interbody implant includes a plurality of superior and a plurality of inferior segments. The segments are adapted to individually expand, contact, and conform to endplates of vertebral bodies to distribute forces equally over the implant and across the vertebral endplates. Once a proper extension of the segments has been achieved, the segments are locked in position. The implant has a stiffness that approximates the stiffness of bone, and the implant minimizes problems with subsidence, endplate fractures, and stress shielding.
