Manufacturer Narrative
|
A review of the device history record showed that the device was manufactured according to specification.The identified deficiency of the scratches of the surfaces during the incoming inspection of the raw material are removed by the subsequent process steps and hence are unlikely to have an negative impact on the stability of the plates (scratches of course may negatively impact the stability of the plates, however, these surface scratches were removed).A root cause could not be identified with certainty.One reason is the lack of documentation of the state of the plate right after surgery and 6 week later at the revision surgery.Without this documentation, the impact on the plate between those two timestamps can not be determined exactly.Even so, the inspection of the device shows a rather extreme bending, which is unlikely to done intentionally by the surgeon.It is also unlikely that continous forces lead to the observed structure.Additionally, the second article (54-25279 - at the distal radius) is reported to be deformed as well, which hints to a larger event and not to a material/product issue.Even though we can not prove it, the most likeliest cause is a sudden force on the plate such as a small accident, (e.G.Falling over).There are no further information available from the customer to verify the claim.
