Manufacturer Narrative

Please note corrections to sections d1, d4 catalog #, gtin and g4 510(k) number.The reported event could be confirmed, since the received nail is broken apart as complained.The device inspection revealed the following: the visual inspection has shown that the nail is broken apart at the lag screw hole.There are strong impression marks from the lag screw in the lag bore visible, which indicates that the nail was exposed to high loads over a longer period of time.Also are some slight marks from intra-operative reaming visible on the whole surface, there is no indication that these marks did contribute to the breakage.The typical characteristics of a fatigue fracture could be identified on both fracture faces.The origin of the crack was at the lower corners at the lag screw entry point, there is a fatigue zone with a smooth surface and progression lines over almost the whole surface of the fracture.The relevant dimensions were verified during the investigation and no deviation from the specification could be detected.A review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.A review of the labeling did not indicate any abnormalities.No indications of material, manufacturing or design related problems were found during the investigation.Based on investigation, the root cause was attributed to a patient related issue.The reported pseudarthrosis did finally lead to a fatigue failure of the implants.In this relation following statement from the instructions for use can be mentioned: ¿these devices can break when subjected to the increased loading associated with delayed unions and/or non-unions.Internal fixation devices are load sharing devices which are intended to hold fractured bone surfaces in apposition to facilitate healing.If healing is delayed or does not occur, the appliance may eventually break due to metal fatigue.Loads on the device produced by load bearing and the patient¿s activity level will dictate the longevity of the device.".If updated information is provided, the case will be reassessed.
