Title: METHOD FOR TREATING A POLYMER WORKPIECE FOR USE IN A JOINT IMPLANT
Abstract:
The present invention provides a method for treating a polymer workpiece (1) for use in a joint implant. It comprises the steps of placing the polymer workpiece in an explosion chamber, introducing a combustible gas mixture into the explosion chamber and igniting the combustible gas mixture. Igniting the gas mixture in the explosion chamber produces a temperature that lies above the melting point of a polymer of the polymer workpiece.
