It was reported that during intertan revision surgery, where devices from a competitor manufacturer were removed from the patient, the intertan 130 degree drop attachment was not "clicking" in to receive the drill guide.The surgeon had to change the surgical technique and manually hold the drill guide during proximal screw drilling/fixation.The procedure was finished with no surgical delay and no injury to patient.

The device, used in treatment, was returned for evaluation.A visual inspection of the returned drop confirms the locking pin is damaged causing the stated failure.The device was manufactured in 2007.The device exhibits signs of significant wear and usage.A medical investigation was conducted and confirms per e-mail communication a revision surgery was performed for nonunion.The implanted system was not a smith and nephew device.Although a change in technique was reported due to the device not being able to lock, no relevant supporting clinical information has been provided to assist with a clinical investigation, and the patient's current condition is unknown.Therefore based on insufficient information, a thorough clinical assessment cannot be performed at this time.Should any additional clinical information be provided this complaint will be re-evaluated.A review of complaint history on the listed part revealed no prior complaint for the listed batch with the same failure mode.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 the risk management file revealed this failure mode was previously identified.This device is a reusable instrument that can be exposed to numerous surgeries; damage from repeated use can occur.Expected wear/tear is likely the probable cause of the reported event.We recommend that all reusable instruments be routinely inspected for wear and damage and replaced as necessary.At this time, we have no reason to suspect that the product failed to meet any product specifications at the time of manufacture.Based on this investigation, the need for corrective action is not indicated.Should additional information be received, the complaints will be reopened.No further investigation is warranted for these complaints; however we will continue to monitor for future complaints and investigate as necessary.We consider this investigation closed.
