Abstract
A prosthetic disc for insertion between adjacent vertebrae includes upper and lower plates and a core having upper and lower curved surfaces disposed between the plates. At least one of the plates and/or the core includes a resilient material for absorbing shock or other forces applied by vertebrae. Optionally, resilient support members may be disposed within the resilient material to connect two portions of a plate or the core. Such support members may be springs, cylinders, wires or other resilient structures. The resilient material is held within the core or plate(s) via a surrounding retaining structure, such as a membrane. The resilient material disposed in one or more components of the prosthetic disc provides for shock absorption.
