Abstract
A method for preserving a component including polymeric material that reduces oxidation degradation after irradiation. The method includes sealing the polymeric material in a container filled with a fluid, preferably a liquid. Monitoring the integrity of the container's seal is enhanced by use of liquid rather than a gas. The method can be used for long term storage of orthopaedic implants which include polymeric material, especially Ultra High Molecular Weight Polyethylene.
