H3, h6: the associated device was returned and evaluated.A visual inspection of the returned device shows the top of the 80mm screw has broken off, rendering the device inoperative.A review of complaint history revealed similar events for the listed device over the previous 12 months, but no similar events for the batch based on the historical data, this failure mode will be monitored for future complaints for any necessary corrective actions.The clinical/medical evaluation concluded that with the limited information provided, the clinical root cause of the breakage of the screws is likely related to the persistent fracture as well complications from the injury and repair that had to be revised over the previous year cannot be ruled out as reasons for the persistent femoral fracture and what is likely fatigue failure of the device.The patient¿s weight bearing status and subject activity level, which were not provided, cannot be ruled out as contributing factors to the reported events as well.The patient impact beyond the revision cannot be determined.No further clinical assessment is warranted at this time.A review of the manufacturing records did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.At this time, we do not have reason to suspect that the product failed to meet any product specifications at the time of manufacture.A review of the risk management file revealed this failure mode was previously identified.A review of ifu for evos¿ plating system revealed in warnings section that it is extremely important to select the appropriate size and type components.Failure to use the largest possible components or improper positioning may result in loosening, bending, cracking, or fracture of the device or bone or both.Besides, precaution section establishes that intraoperative fracture or breaking of instruments can occur.The anticipated risk level is still adequate.Assessment of historical escalated cases concluded that there are no prior actions related to this device and failure mode.As the device broke and it can no longer fit its purpose, the contribution of the device to the reported event could be corroborated.Some potential probable causes for this event could include but not limited to traumatic injury, surgical technique, or implant failure.Based on this investigation, the need for corrective action is not indicated.Should additional information be received, the complaint will be reopened.No further investigation is warranted for this complaint; however, we will continue to monitor future complaints and investigate as necessary.We consider this investigation closed.
