H10, h3, h6: the reported device, used in treatment, was received for evaluation.There was a relationship found between the returned device and the reported incident.A visual inspection revealed that the device was returned without any of the complementary components.The internal wire appeared to be connected to the rotating cutter.There was significant debris within the cutter and on the shaft.A functional evaluation concluded that the device cutter is unable to rotate out of the shaft fully.It seemed to be connected to the grey slider still and moves slightly, but was not able to fulfill its intended purpose.A review of the device records showed there were no indications to suggest that the product did not meet manufacturing specification or would not be able to perform as intended.A complaint history review concluded this was an isolated event.A review of risk management files found that the reported failure was documented appropriately.A review of the instructions for use found the following warnings and precautions related to the reported failure: read these instructions completely prior to use.The cannulated power drill must always be set to forward when drilling tunnels and retrograde-drilling sockets.Prior to deploying the cutting blade, ensure that the guide wire is retracted within the groove approximately 1.5 inches (38 mm) within the retrograde drill shaft and is not in the drill head window.The groove in the guide wire provides tactile feedback that it is retracted to the proper position.This will prevent possible device failure.The device is intended to drill in a retrograde motion only when cutting blade is deployed.Antegrade drilling while the cutting blade is deployed may result in device failure.Use only the smith & nephew devices provided in the retrograde drill kit.As with any surgical instrument, careful attention must be exercised to ensure that excessive force is not placed on the instrument.Excessive force can result in instrument failure.The complaint was confirmed.Factors that could have contributed to the reported event include failure to retract guide wire, excessive force during use, use of the reverse function when drilling, or improper drilling direction when the cutting blade is deployed.
