H3, h6: the associated device was returned and evaluated.The visual inspection revealed that the screw fractured into two pieces.Only the head of the screw was returned.The clinical/medical investigation revealed that the evos screw is comprised of stainless steel, and it is approved for implantation.According to the report, the body of the screw was left secure in the patient¿s bone, therefore, the potential for micro-motion and/or migration is unlikely.Per report, the surgeon completed the procedure without a delay using a backup device and the patient was in stable condition at the completion of surgery.The impact to the patient beyond that which has been reported cannot be confirmed nor concluded.Should any additional relevant medical information be provided, this case would be re-assessed.Device batch number was not provided, thus, an evaluation of the manufacturing records could not be performed.A review of complaint history for the previous 12 months did not reveal similar events for the listed device.A review of the instructions for use documents for mini-fragment plating system reveals in the 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 fracture of the device or bone or both.A review of the risk management file revealed this failure mode was previously identified.The anticipated risk level is still adequate.A historical review concluded that there are no prior actions related to this product and event.According to the material specification, the quality and manufacture of special quality stainless steel shall be controlled.Based on this investigation, it was concluded that the evos 2.4mm cortex screw fractured due to forces incurred during the adjustment referenced in the complaint statement.It is not clear if a fracture was initiated during insertion or other activities during surgery.At this time, we have no evidence to conclude that the product failed to meet any specifications at the time of manufacture.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 for future complaints and investigate as necessary.We consider this investigation closed.
