H10.Additional information in a2 and a3.H3, h6: given the nature of the alleged incident, the device could not be returned for evaluation.However, the clinical/medical investigation concluded that, the imaging shows a fractured nail at the proximal lag screw hole in the presence of probable non-union of the initial subtrochanteric fracture.Early weightbearing, advanced age, metabolic disorders as well as circulatory and inflammatory disorders are known risk factors to pseudarthrosis/non-union and reportedly the patient has severe systemic disease which can be seen in the imaging as significant vessel calcification.Although a definitive clinical root cause cannot be concluded, the patient¿s preexisting comorbidities and activity cannot be ruled out as contributing factors to the fractured nail as the presence of improperly healed bone is known to increase the stress and fatigue of metallic implants.A review of the production order did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.A review of complaint history for the part number over the past 12 months and for the batch number based on historical data of the device did not reveal similar events for the listed device.A review of the instructions for use documents for intramedullary nail system revealed in possible adverse effects that cracking or fracture of the implant may occur.Preoperative planning section states that proper type and size of implant must be selected to ensure effective treatment of patients considering factors such as patient¿s size, strength, skeletal characteristics, skeletal health, and general health.Overweight or musculoskeletal deficient or unhealthy patients may create greater loads on implants that may lead to breakage or other failure of the implants.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 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.
