Manufacturer Narrative

G3, h2, h3, and h6: a bhr square headed nail was received for inspection.The instrument was intended for use in treatment.A visual inspection was performed.It was observed that small marks and scratches were present across the whole length of both instruments.The tip of the nail did not appear to be blunt/dull.Batch numbers of the instruments were faded and non legible.The nail head had broken away on both instruments inspected.A functional evaluation was not needed as the failure had been confirmed through visual evaluation.Testing was also performed on 3 nails affected by the same issue (from semi finished batch 01129965).All 3 nails tested failed within 6 cycles.The acceptance criteria per the protocol was not met by any of the three tested nails.A review of the complaint history for the bhr square headed nail was performed using batch numbers in search of similar recurring reports for the products during their lifetimes.Similar complaints have been identified for the square headed nail.The other 3 complaints relate to the head falling off the pin, this will continue to be monitored.The labelling of the instrument was found to be correct with no issues noted.A risk management review was performed.The risk was identified within the risk file.Due to the fact that the nails have not been manufactured in the correct way, the risk documented risk assessment for the nail does not apply.Another risk assessment was performed and a high risk was identified, due to the frequent occurrence of instrument failure.No additional risks were identified as result of the reported event.Quality escalations were raised to stop any further distribution of the parts that may be affected, further quality investigations were raised to find the potential root cause and correct the issue to ensure that it does not happen again.A health hazard evaluation was performed to evaluate the potential risk that the issue may have to patients and health professionals which concluded that it was appropriate to initiate a field action for the affected parts.A product prints/specifications/procedure review was performed.It was discovered that parts were being manufactured to a different mahe drawing.This design calls for nail attachment to the block using a blind-hole and welding, which has resulted in the failure of the head becoming detached from the pin.The specification change was not communicated to smith and nephew.Based on the returned instrument and investigation a probable root cause for the head becoming detached from the pin is device design, caused by an unauthorized drawing change by the supplier.The instrument cannot be fixed and will be retained at aurora.D10: add concomitants g2: report source update h6: update codes d8 and d9: device returned.
