The resulting local heating might partially transform the microstructure of the prostheses. In the present case a flashover to the in situ titanium hip endoprosthesis during the revision of a fractured ceramic head decreased the fatigue strength of the prosthesis and ultimately caused its failure. During revision surgery it is essential to prevent contact between in situ metal components and high-frequency cauterising instruments. © 2009 Springer Medizin Verlag.en1433-043120097622625SpringerEndoprosthesesFlashoverHigh-frequency electrocauteryMicrostructural transformationRevision surgeryMedicine, HealthEngineeringJournal Article10.1007/s00132-009-1442-6Journal Article
