1. A method for repairing a damaged intervertebral disc defined by an outer annulus fibrosus and an inner nucleus pulposus comprising the steps of:

  • (a) introducing through the annulus fibrosus and into the nucleus pulposus of the damaged disc a biologically inert thermoplastic elastomer in the liquid state with sufficient pressure to reinflate the damaged disc to its normal undamaged dimensions; and

    (b) curing the thermoplastic elastomer to a hardness sufficient to support normal postural compressive loads and thereby prevent the disc from returning to its damaged dimensions.
