The explanted device was returned to orthopediatrics in warsaw, in and was subjected to cleaning, steam sterilizing, and engineering evaluation.Because the device was electively removed, a wear investigation was conducted using a hitachi s-3400n scanning electron microscope at purdue university fort wayne.The spherical ring was removed from the implant for investigation.It appeared that the outermost layer of the adlc coating had been worn through but did not appear to breach completely to the base material.Region a of the sem investigation showed superficial scratching.The dark region appeared to be foreign material simply sitting on the surface of the part, likely from manual handling and loading the component into the machine.Region b showed superficial scratching and possible spalling.There were no obvious manufacturing or design defects which contributed to the removal of the device.
