The device was not returned for evaluation; therefore, a device analysis could not be performed.The clinical/medical investigation concluded that, during the total knee arthroplasty surgery the 110 speed pin broke in the tibia and was left in situ.The externally communicating device is neither manufactured nor intended for implantation; therefore, no long-term exposure with skin or tissue data is not available.The procedure was resumed, without any delay, using the same device.The patient impact beyond the reported device breakage/retained foreign body during the procedure could not be definitively determined.Although unlikely, the potential for corrosion and local irritation/migration of the fragment could not be ruled out.No further medical assessment can be rendered at this time.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 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 speed pins provides complete guidelines for indications, contraindications, warnings and precautions to be aware of preoperative, during surgery or postoperative.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.This device is a reusable instrument that can be exposed to numerous surgeries.Damage from prolonged use, misuse or rough handling are likely potential factors that could contribute to the reported event.We recommend that all reusable instruments be routinely inspected for wear and damage and replaced as necessary.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.
