Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional information.The complaint is confirmed.It was reported that the patient fell off a ladder on july 9, 2018 and the ribfix blu plates were installed on october 5, 2018.The patient experienced a heavy coughing attack on may 2, 2019, which was followed by pain and swelling in the area of the scar on the right side.A ct scan on may 15, 2019 showed the implants were fractured and they were then explanted on may 17, 2019.Visual evaluation of the 12 hole plate and the provided scans showed that the plate was fractured at the 6th and 8th screw holes, where the plate had been bent in both locations.The 12 hole plate was placed on rib 7.The 16 hole plate was fractured in one location, at the 5th screw hole, near where the bend was placed.The scans also showed that the ribs 1-9 were fractured and there was non-union at each fracture, however, only ribs 7 and 8 were plated.The 12 hole plate on rib 7 appeared to be free-floating on the end near the spine, however, it could not be determined if there was a screw that lost purchase or if this hole was never fixated.The dhr's for these plates could not be reviewed due to the lot numbers being unknown.There are no indications of manufacturing defects.For this part (76-2602) and the previous one year (from the notification date) regarding the fracturing of this plate, there is a complaint rate of 0.049% which is no greater than the occurrence listed in the application fmea.The most likely underlying root cause of the fracture is the reported extreme coughing attack.It is possible that the sharp bend angles observed in the provided ct scans contributed to the fractures, as they may have caused fatigue in the plates.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.
