Event Description
|
It was reported that the patient suffered from complete backing out of lateral to medial screw in nail, partial backing out of medial to lateral distal interlocking screw in nail, breakage of most proximal of the distal interlocking screws in nail, and breakage of distal most screw in the nail after having a fracture fixation surgery of the right femur using the trigen retrograde femoral nail system.Overall, alignment was maintained with callus formation, but healing was not complete (nonunion).The patient also suffered from a hematoma likely related to prominent screw.The screw was removed.The current state of health of the patient is unknown.This incident was noticed in a retrospective post-market clinical follow up activity (pmcf) where anonymized data summarizing outcomes were gathered; therefore, additional information is not known, and it is not possible to collect it.We do not have the opportunity to identify individual hcps and revisit negative feedback to retrieve further information.

H3, h6.Given the nature of the alleged incident, the device, could not be returned for evaluation.The clinical/medical investigation concluded that, as of the date of this medical investigation, the requested clinical documentation has not been provided; therefore, there were no clinical factors found which would have contributed to the event.Consequently, without clinically relevant patient-specific supporting documentation, a thorough medical investigation could not be performed.The root cause and/or patient outcome beyond that which was already reported could not be confirmed nor concluded; therefore, no further medical assessment is warranted at this time.Device specific identifiers were not provided.Therefore, an evaluation of the manufacturing records, complaint history review, instructions for use, risk management file, prior actions review and product prints review could not be performed.At this time, we have no reason to suspect that the product failed to meet any product specifications at the time of manufacture.With the results of this investigation the root cause of this event could not be determined.Factors that could contribute to the reported event include post-operative healing issue and/or patient condition.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.
