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 based on the information provided the root cause of the nail breakage is due to a fall occurring approximately 3 years post implantation.One single undated x-ray provided demonstrates a breakage of the nail at the lag screw hole; radiolucency is noted around the stem, which could have contributed to the breakage if loose.It cannot be concluded if the fall resulted in the broken nail or the broken nail resulted in the fall.Per communications, the patient¿s condition is unknown.Therefore, the impact to the patient beyond the reported fall, the subsequent revision and the post-op convalescence period cannot be determined.Should additional medical information be provided this complaint would be re-assessed.A review of complaint history did not reveal additional complaints for the listed batch.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 but not limited to traumatic injury, surgical technique, implant failure or design of device.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.
