Manufacturer Narrative

Section h3, h6: the device was not returned for evaluation but the pictures were reviewed, and they confirm the backout of the lag and compression screw.The clinical/medical investigation concluded that, the provided x-ray and ct scan reports confirmed the backout of the lag and compression screw as well as the comminuted fracture of the greater trochanter.However, the clinical root cause of the reported events cannot be determined.The impact to the patient beyond that which has already been reported cannot be determined.However, it was noted that following the removal of the s+n components and tha conversion procedure, the patient developed foot drop, prosthetic infection, hypertensive emergency, and renal failure.These developments are most likely related to the procedure and the patient¿s previous diagnoses of type ii dm and hypertension.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.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.A review of the instructions for use documents for intramedullary nail system revealed that loosening has been identified as a possible adverse effect.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.At this time, we have no reason to suspect that the product failed to meet any product specifications at the time of manufacture.Factors and/or some potential probable causes that could contribute to the reported event have been identified as abnormal motion over time, bone degeneration, fit/sizing issue, lack of ingrowth, lifetime of device, and/or traumatic injury.The contribution of the device to the reported event could be corroborated since the backout of the screws caused the replacement of the nailing system.Based on this investigation, the need for corrective action is not indicated.Should the device or 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.
