Event or Problem Description
It was reported that one sternal plate fractured and screws backed out of a plate seven months post-operatively.In (b)(6) 2019, three plates and ten screws were implanted in a ravitch procedure correcting pectus excavatum.In (b)(6) 2019, the implants were removed and replaced with new plates and screws.The patient is reported to be in good condition following the revision surgery.No additional patient consequences were reported.
Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional information.As there was a revision surgery, the complaint is confirmed.There are no x-rays, scans, or physician's reports available.A visual inspection was conducted and the products show heavy wear.The qty three 73-1952 plates have been bent as well as cut.It cannot be determined if this occurred pre or post operation.The screws appeared to have damage on the locking threads, which could indicate that they did not get fully locked into the plate during insertion.The dhr was reviewed and there were no non-conformances found.There are no indications of manufacturing defects.For this part (73-1952) and the previous one year (from the notification date) regarding the screw coming loose post op, there is a complaint rate of 0.09 %, which is no greater than the occurrence listed in the application fmea.This is the only complaint in regards the screw backing out for 73-1952 lot j143660.Because of the lack of information, the most likely underlying cause cannot be determined, though it is possible the screws were not fully inserted and locked into the plate.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
