Reported event was confirmed by review of photographs provided.Based on these inspection findings, it was determined that the root cause of the rust is associated with the radel material that is used in the plastic components in the kit.There is chlorine releasing from the radel material in parts per million, during gamma sterilization, that results in oxidation of the drill bits when exposed to extreme environmental conditions such as those experienced during transport.Dhr was reviewed and no discrepancies were found.Review of the complaint history identified an issue that was already addressed in the past.Completion of the investigation relayed to biomet (b)(4).If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.(b)(4).
