Event Description
|
This event is reportable due to the product mix in the central sterile processing which resulted in the wrong guides being used in the patient.Two cases involving prophecy guides became mixed up in central sterilization.The first case appeared during surgery, and it was only when the tibial corner holes were drilled that the mistake became evident.The error was traced back to the mixing up of prophecy guides.The surgeon switched to standard instrumentation but inadvertently caused a medial malleolar fracture during the insertion of the tibial component, only detected six weeks later through x-rays.Despite the fracture, the patient chose non-surgical treatment due to work commitments, and the patient experienced relief from pain.Multiple discussions were held about potential revision, but the issue was attributed to technical errors rather than the implants themselves.An update on a later dat, clarified that the primary surgery for this patient is (b)(4), with pi# (b)(6) addressing the revision surgery/primary implants only, and pi# (b)(6) addressing the allegations of mixed up guides and the medial malleolar fracture.Feedback from the sales representative indicated that the mix-up was a result of a processing error in the sterilization department due to staffing shortages and the use of temporary staff.Additional information provided on a later date, confirmed that the guides from one patient were indeed used in another patient's surgery on the same day.The entire set of guides was placed incorrectly, staged for surgery.However, the guides from different cases were not mixed together.The mix-up occurred because the patient information labels on the guides were swapped.The process involved the sales representative delivering and filling out an intake form for the equipment brought in, with sterile processing handling the items and placing them on case carts for each surgery.

The reported event was confirmed based on information received from the sales representative.Based on investigation, the root cause was attributed to a user related issue.As noted by the sales representative, the failure was caused by a processing error by the facilities sterilization department.The prophecy guides were labeled with the incorrect patient information during central sterilization.The prophecy guides were mixed-up with guides for a different surgical procedure as a result.A review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.A review of the labeling did not indicate any abnormalities.The instructions for use were reviewed and states: "markings on guides and models provide case identifiers, such as case number, and must be legible.Before using the guides and models, check the identifier and confirm that it corresponds with the current case.Do not use the guide or the model if the case identifiers are not legible." no indications of material, manufacturing or design related problems were found during the investigation.If the device is returned or if any additional information is provided, the investigation will be reassessed.
