Please note the correction to d9/h3.The reported event could not be confirmed, since the device was not returned and no additional information was available.However, few questions were received which were analyzed and described as below, 1.It is possible that in this case, a young man with good bone quality and muscular thighs was putting too much strain on the targeting device.- definitely.This is possible in good bone quality, but also in a narrow bone marrow within the shaft region, which can make the nail deviate from the orientation of the targeting device.2.Is it possible that the screw holding the nail and jig together could have come loose while tapping the nail in? maybe but i tightened it myself which is usually more than enough.I can get to 170 psi with my right-hand grip strength - that is not likely to be the cause of the problem, the way-grip strength is not helpful in solving this kind of event.It is crucial, that the placement of the nail and the insertion of the guide wire should be performed with almost no force to prevent it from deviating.The drilling should be performed with sharp (!) drills and without the need to use grip strengths or physical effort.3.Is it possible that the removable locking part does not rigidly hold the guide sleeves in place? does the carbon fiber jig need to be stiffer? - the fiber jig is very stiff.In contrast, the titanium allows some movement and consecutively a deviation from the axis.4.Does the sleeve need inferior spikes to prevent superior deflection and anterior and posterior spikes to prevent ap deflection? - intent of the question is not completely clear but as far as understanding the problem it is more likely related to the nail instead of the sleeve.5.Would having a single double-lumen sleeve prevent deflection as each sleeve was deflecting independently of each other? once the wires are in, can a single double lumen sleeve be replaced with separate single lumen sleeves as we have now? - usually, this is not identified as being a general problem.6.Having placed the guide wired centrally in the femoral head on the lateral films, i proceeded to remove one wire, drill, insert the screw and then do the same for the upper screw as you op tech suggests.It was shocking to see both screws sited posteriorly in the head afterwards.This has never happened before on any device that i have used.It is possible that the same deflection may have occurred posteriorly with the drill? - yes, it is possible that the same deflection may have occurred posteriorly with the drill.The elder generation of drill allow for some deflection due to some flexibility in very dense bone or as the result of a user problem.7.Is it therefore possible to allow us a have an inner sleeve that allows a cannulated drill that runs over the wire (i.E.Leaving the wire in the correct position) to as to prevent deflection of the drill as well? - the intent of the question is not clear, but if inserted without too much force and without pushing the targeter and if the drill is sharp, no deflection should occur.A cannulated drill is not foreseen in the operative technique in my opinion-is not necessary as the orientation is controlled when the drill is passing through the nail.[original statements] a review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.A review of the labeling did not indicate any abnormalities.No indications of material, manufacturing or design related problems were found during the investigation.More detailed information about the complaint event as well as the affected device must be available in order to determine the root cause of the complaint event.If any additional information is provided, the investigation will be reassessed.
