The present invention provides both a device and a method. The device is a human made replacement for the soft discs in the spine. A fabric pouch encloses a central hydraulic element made up of small soft beads. Two pouches with beads are implanted into a prepared disc space to function as an intervertebral disc. The method is conversion of the device into a fusion element.
