Manufacturer Narrative

(b)(4).This final report is being submitted to relay supplemental information.Complaint summary: a visual inspection of the oxford trial bearing medium sz 4/5 (item: 32-420378 lot: 299607) shows a fracture through the thread insert locking pinhole on the size 5 trial bearing.Both the plastic bearing ends are showing wear and damage on all surfaces with small cracks visible on the size 4 end around the thread insert.The mhr related to the involved product cannot be found as there was no requirement at the time of manufacture to retain the dhr indefinitely.The reported event is not related to a combination of products; therefore, a compatibility review is not applicable.A dimensional inspection is not applicable for this reported event.The likely condition of the device when it left zimmer biomet is conforming to the specification.The definitive root cause of this event cannot be determined with the available information; however, as the product has most likely had many years of use in the field (wear and tear) may have been a contributing factor.The investigation is completed based on currently available information.If any additional information becomes available, then the complaint will be reopened and investigated.It has been confirmed that the implant is not within the scope or subject of any field actions or recalls which could be attributed to the reported events.This device is used for treatment.A review of the complaints database shows that we have received 3 reported events for instrument fracture for the same item number 32-420378 prior to the reported event.It was confirmed that the reported harm/hazardous situation, instrument fracture, is addressed in the associated risk management file for the reported product however as the failure mode associated with the reported event is unknown, a specific risk line item cannot be identified.If any additional information is discovered or received that may adjust any conclusions or data, a supplemental report will be generated accordingly.Zimmer biomet will continue to monitor for trends.
