Product complaint # (b)(4).Investigation summary = > no device was returned.Root cause undetermined depuy synthes considers the investigation closed at this time.Should additional information be received, the information will be reviewed and the investigation may be re-opened as necessary.Investigation methods: was patient affected: yes.Device history reviewed: yes.Lot trace obtained: no.Complaints database searched: yes.Product checked: no.Label checked: no.Product pulled from stock for inspection: no a review of complaint databases did not identify any anomalies.A manufacturing record evaluation was performed for the finished device lot 674463 and no non-conformances were identified the x-rays were reviewed by bioengineering and a report was received stating; it can be seen that the right femoral head is not centralised in the cup.This could possibly be due to liner disassociation or liner wear.The image (b)(4) provided suggests that the liner may have disassociated from the shell.Reviewing the photo provided ((b)(4)): the wear visible on the rim of the liner may suggest impingement with the femoral stem or retrieval damage, however it is difficult to confirm either as the parts have not been returned for visual inspection.From this photo, it is not possible to investigate the femoral head.Conclusion: as stated in the event description, the screws were reported to be protruded.This would impact the seating of the liner, however it is not possible to investigate this from the information provided.It should be noted that the mode of failure of the prosthesis is multi-factorial and consideration has to be given to all other potential influences such as, surgical process, patient variables e.G.Activity, weight, bmi and use, anatomical considerations and patient changes over time.This report details the findings from a review of the given x-rays and information as supplied at the time of evaluation.Any conclusions from this data have to be placed into context with all other relevant factors.Without the physical complaint sample(s) associated with this report, it was not possible to determine if the device(s) failed to meet specification(s) at the time it was released for distribution.The device(s) associated with this event were used in the treatment of the patient as prescribed by the presiding surgeon.From the event information received, it was not possible to determine the relationship of the device to the reported event no information received with this individual complaint indicated that a broader investigation or corrective action was necessary.Depuy synthes considers the investigation closed at this time.Should additional information be received, the information will be reviewed and the investigation may be re-opened as necessary.The complaint shall be closed with an undetermined conclusion; entered into the complaints database and monitored through trend analysis.Post market surveillance is per (b)(4).Device history lot = > a manufacturing record evaluation was performed for the finished device lot 674463 and no non-conformances were identified if information is obtained that was not available for the initial medwatch, a follow-up medwatch, a follow-up medwatch will be filed as appropriate.
