A capsule-shaped prosthetic spinal disc nucleus for implantation into a human intradiscal space, made of a substantially inelastic constraining jacket surrounding an amorphous polymer core. The constraining jacket has a generally fixed maximum volume and defines a height. The amorphous polymer core fills an initial volume of the constraining jacket and develops an internal pressure. In response to the internal pressure, the constraining jacket transitions toward the maximum volume, increasing substantially in height.
