Product complaint # (b)(4).Depuy synthes is submitting this report pursuant to the provisions of 21 cfr, part 803.This report may be based on information which depuy synthes has not been able to investigate or verify prior to the required reporting date.This report does not reflect a conclusion by fda, depuy synthes or its employees that the report constitutes an admission that the device, depuy synthes, or its employees caused or contributed to the potential event described in this report.H3, h6: investigation summary background.The occipito synapse system was used for a surgical procedure for cervical occipital fixation.There were no inconveniences for cervical fixation.At the time of performing occipucio fixation, through proper and reviewed technique by the medical team, it is not possible to carry out the fixation, the screws were not fixed, probably due to lack of edge of the male used.It was necessary to perform 11 perforations in the patient's skull, without achieving success with the technique described.Finally, the surgeon used screws of less diameter, achieved adequate drilling to finalize the fixation.The surgery lasted approximately 10 hours.This procedure does not last more than 5 hours.Concomitant device reported: unknown occipital plate (part# unknown, lot# unknown, quantity unknown) unknown rod (part# 04.161.030 , lot# unknown, quantity 2).This complaint involves ten (10) devices.Customer quality investigation: the tap f/cortscr ø4.5 w/cardan joint l245 (part # 03.161.027, lot # unk) was not returned, and the investigation will be completed based on the supplied images from the attachments (2 images from the attachment located in notes & attachments section of the product complaint).The images were reviewed, and the complaint condition could not be confirmed as the image did not provide enough clarity to show any issues with the tap.Based on the images of the tap, it appears that the cutting edges are in good shape.There is not enough evidence in the attached photographs to determine if the tap is dull.A part#/lot# was not visible with the attached photo so no manufacturing record evaluation was conducted.Conclusion after reviewing the returned photographs, the complaint cannot be confirmed as there is not enough evidence to conclusively determine the presence of a dull tap.During the investigation no unidentified product design/manufacturing issues or discrepancies were observed (based on the images) that may have contributed to the complaint condition.Based on the event description, it sounds as if the tap was successful in tapping a hole but the alleged screws had a failure.Additional monitoring for any potential safety signals will be conducted through complaint trending and other post market safety surveillance activities.Based on the investigation findings, it has been determined that no corrective and/or preventative action is proposed.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
