Abstract

Implants and methods for spacing and stabilizing vertebral members. The implant in one embodiment may include first and second endplates and an intermediate section that form an interior section. An elastic member may be positioned within the interior section to space apart the endplates. The elastic member may have a variety of orientations, sizes, shapes, densities, modulus of elasticity, and other material properties depending upon the desired displacement between the first and second endplates. In use according to one embodiment, the implant may assume a first shape when the vertebral members are aligned, such as when the patient is standing erect or in a prone position. This first shape may include the first and second endplates spaced a first distance apart. During movement of the vertebral members, the endplates may be forced together. The intermediate section in combination with the elastic member may be deformed during this movement and thereby exert a force to stabilize the vertebral members.
