(b)(4).Foreign event occurred in (b)(6).The product was returned and lab analysis was performed.The mixing rod event was not observed on the returned product.A reserve sample from the same lot was evaluated and the reported event on polymerization time was confirmed.Testing was performed under standardized conditions and the sample tested showed that the application phase was in compliance with specification, and the setting phase was too short with respect to the specification.As the cement must be applied during the application phase, and not during the setting phase, the too short polymerization time does not have an impact on the function of the product.The review of the device manufacturing quality record indicates that (b)(4) products optipac 40, refobacin plus bone cement-3, reference 4720502083-3, lot number 736ba04790 were manufactured on 20 october 2017.The device manufacturing quality record indicates that the released product met all requirements to perform as intended.No non conformity or deviation was observed which could be linked to the complaint events.No other complaint concerning polymerization time has been recorded for optipac 40 refobacin plus bone cement-3, reference 4720502083-3, lot number 736ba04790.This event is a one-off.With the available information, the exact root cause of the event could not be determined.An investigation has been performed, consisting of a documentary review and a product analysis.The documentary review showed that product was manufactured according to the pre-defined specifications of biomet (b)(4).The product analysis showed that the too short polymerization time does not have an impact on the function of the product.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
