Manufacturer Narrative

The device, used in treatment, was not returned for evaluation.Therefore, product analysis could not be performed at this time.So the reported event could not be confirmed.A medical investigation was conducted and confirms the intraoperative findings of pseudotumor as well as the reported cobalt toxicity and subsequent deafness, blindness, hypothyroidism, and tachycardia may be consistent with metal debris as a result of having metal components implanted after fractured ceramic implants.This was also confirmed by the surgeon noting wear in the revised components.The patient impact cannot be determined; however, a physician¿s post revision follow-up note indicated, from a hip perspective she has recovered beautifully.Having less trouble with tach.Being followed by internist and cardo at home, has bilateral hearing aids and wears glasses.A review of complaint history on the listed part revealed no prior complaints for the listed batch with the same failure mode.A review of the manufacturing records did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.A review of risk management files and instructions for use found that the reported failure was documented appropriately.Some potential probable causes for this event could include damaged product, implant corrosion or wear.At this time, we have no 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 not indicated.Without the actual product involved and/or device information, our investigation cannot proceed.If the device or new information is received in the future, this complaint can be re-opened.No further actions are being taken at this time.We consider this investigation closed.
