Event or Problem Description
It was reported that a custom cranial implant was larger than the defect.After an initial investigation, it was discovered the implant was designed using the wrong patient's scans.The issue was discovered the day before the planned surgery date.No adverse events have been reported as a result of the malfunction.
Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional information.The design vendor of this part confirmed the complaint that the implant was incorrectly designed.It was found that the uploaded dicom folder did not contain any part of the patient name that was indicated on the design input form.Searching for the patient name included in this dicom folder led the investigation to case pm622795.Case pm622795 was created on signature ftp on the same date as case pm622790.This upload error of the dicom folder thereby led to the processing of case pm622790 with the images of case pm622795.The error could not be identified during the triage procedure, as the location of defect field of the design input form was not filled and all parameters passed as per work instructions.The design/e-manufacturing was reviewed, which confirmed the incorrect dicom files were uploaded to the folder for this case.The dhr for this product was reviewed; no non-conformances were found.However, the design vendor confirmed that the incorrect series of patient images were used in the creation of this component.For patient matched htr-pmi implants (pmxxxxxx) and the previous year (from the notification date) regarding fit issues with the implant, there is a complaint rate is 1.68%, which is no greater than the occurrence listed in the application fmea.The most likely underlying cause of the complaint is due to an operator error.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.
