Abstract

An nucleus prosthesis is disclosed having a plurality of linked segments configured to form, in a closed position, a disc shape. A method includes inserting a plurality of linked segments into an annulus fibrosus and closing the prosthesis so that a first segment inserted into the annulus fibrosus and a last segment inserted into the annulus fibrosus are substantially abutted. Another method includes inserting a plurality of linked segments into an intervertebral disc space and closing the prosthesis so that a first segment inserted into the intervertebral disc space and a last segment inserted into the intervertebral disc space are substantially abutted.
