Manufacturer Narrative

Complaint sample was not returned for evaluation; however, x-rays were provided and evaluated: device history records: the lot records were reviewed and no problems were identified that could have caused or contributed to the complaint.Failure analysis - the part has not yet been returned to integra for investigation, but x-ray images were provided.Evaluation of the x-ray image shows that a peg of the talar dome was broken off from the talar dome at the point where the peg joins the dome.The failure was confirmed.As the part has not yet been returned, a definitive root cause cannot be determined.According to risk management documentation for the cadence total ankle system, there are several identified failure modes which could result in breakage of the talar dome, including inadequate design and incorrect or inadequate surgical technique.If the part is later returned this complaint may be reopened and an analysis performed.
