H3, h6: the navio checkpoint verification pin, part number pfsd01009, used for treatment was not returned for evaluation; thus, a visual and functional evaluation could not be performed, and a relationship between the reported event and the device could not be determined.While all products meet required manufacturing specifications prior to release a serial number or lot number is required to link the device to a dhr or nc investigation.A complaint history review for similar reported/confirmed complaints concluded this was an isolated event.Although the reported problem was not confirmed, a factor that may have contributed to the reported symptom may have been associated with improper use/handling of the part.The navio surgical technique guide (500197) provides instructions to finish the implantation of the final components, as recommended in the applicable implant surgical technique, using appropriate instruments and tools.This failure is an identified failure mode within the risk assessment.This complaint from australia reports that the surgeon used navio checkpoint verification pins after being advised that the construct was stainless steel and was not compatible with the cobalt chrome component.No patient injury or impact was reported and the patient and surgeon were satisfied with the surgical outcome.Smith & nephew has not received adequate materials (operative reports) to fully evaluate the complaint, but if additional clinically relevant materials are later received the complaint can be reopened.Although no further containment or corrective action is recommended or required at this time, all complaints are monitored and trended through post market surveillance activities.If the product associated with this event is returned or provided at a future date, this evaluation will be reopened for investigation.Additional information: d3.
