Manufacturer Narrative

An event regarding revision involving a gmrs femoral component was reported.The event was confirmed by product inspection.Method & results: -product evaluation and results: a material analysis report indicated, ¿"the medial and lateral surfaces of the prosthesis.Damage was observed on the medial surface of the prosthesis, potentially due to the explantation process.Damage was observed on the two screw heads on the lateral surface of the prosthesis.¿ ¿damage was observed on the tip of the screwdrivers and screw heads of the prosthesis.One of the screwdriver tips fractured in the safety screw of the prosthesis.The tip likely prevented the screw from being accessible for tightening and loosening.Damage potentially due to off-axis loading between the screwdrivers and screws were also observed.Based on the given information, no identifiable materials or manufacturing discrepancies were observed on the surfaces examined." -clinician review: not performed as medical records were not provided for review.- product history review: a device history review confirmed all devices accepted into finished goods conformed to specification.-complaint history review: no other events were reported for the lot indicated.Conclusions: the investigation concluded that the revision took place as the growing prosthesis could not be extended in a previous procedure.The screw heads on the prosthesis were found to be damaged from off-axis loading.No further investigation for this event is possible at this time as insufficient information was received.If additional information becomes available to indicate further evaluation is warranted, this record will be reopened.Product surveillance will continue to monitor for trends.
