ABSTRACT:
A method for revision arthroplasty for the removal of a loosened or defective prosthesis component anchored in a polymer cement set in a bone cavity. The method comprises exposing and disconnecting, if necessary, a connecting free end portion of the prosthesis component at an extremity of the bone cavity. The loosened or defective prosthesis is then removed out of the bone cavity from the extremity thereof. The cement is then removed from the cavity by the use of an instrument having a heated working end which is heated to a temperature exceeding the melting point of the cement whereby cement can be removed without perforating or damaging the bone.
