The products were returned to the manufacturer on february 25th 2019.Yet, the decontamination form received on february 26th 2019 stated that the disinfection/cleaning was not performed.The device was received in condition making evaluation impossible.From the information provided, the product history records, the review of the case and the recurrence of this type of event for this product, the investigation found no evidence to indicate a device related issue.Indeed, it could be hypothesized that the implant underwent a preoperative damage not revealed, causing its break.However, without the product evaluation, this hypothesis cannot be validated.The root cause of the reported event remains undetermined with the most likely hypothesis of user error.If additional information is received that allows to draw a conclusion, this case will be reopened and the root cause of the complaint will be reevaluated.
