Abstract
A method for replacing a nucleus pulposus of an intervertebral disc. The method is achieved by removing the nucleus pulposus from the intervertebral disc to create a space defined by an inner wall of a annulus fibrosis. A flexible prosthetic disc is then inserted within the space formerly occupied by the nucleus pulposus and the prosthetic disc is subsequently filled with a gel.
