Internal complaint reference: case-(b)(4).H6: the associated device was returned and evaluated.A visual inspection of the returned device reveals the legion narrow ps oxin sz 4n lt was labeled on box as a legion narrow ps oxin sz 5n lt but the stickers indicated it was a 4n left narrow femur.The visual also reveals bone cement on the actual implant.A review of complaint history for the part number over the past 12 months and for the batch number based on historical data of the device did not reveal similar events for the listed device.A review of the manufacturing records did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.However, a review made by the quality engineering team revealed that the root cause of this issue was that during the reprocessing of the outer labels for batches 23em09868 and 23em09878, a paperwork or labeling mix occurred resulting in the reprinted labels being applied to the incorrect product.The standard rework process was not followed and a new rework order was not created and label verification was not performed.Final visual inspection failed to identify the discrepancy.This issue was identified and is being addressed though our internal quality process.According to label specification, the size on the outer label should be 4n.Assessment of historical escalated cases concluded that there are no prior actions related to this device and failure mode.At this time, we do have reason to suspect that the product failed to meet any product specifications at the time of manufacture.Based on this investigation, the need for corrective action is indicated.Should additional information be received, the complaint will be reopened.No further investigation is warranted for this complaint; however, we will continue to monitor future complaints and investigate as necessary.We consider this investigation closed.
