Event Description
|
It was reported that a revision posterior lumbar fusion procedure was performed on (b)(6) 2020, utilizing the reform pedical screw system.Upon attempted removal of a 6.5 x 40mm reform pedicle screw (not ha coated), that was originally implanted on (b)(6) 2018, the tip of the retention bone-screw driver (39-sp-0601) broke and could not be removed from the head of the screw.The doctor then "helicoptered" the screw out and was able to successfully replace with a new screw.This resulted in a ten (10) minute delay to the procedure.The revision was performed due to degeneration around the previous fusion, not to failure of precision spine product.

H3 device evaluation - the driver tip was examined by eye as well as with the aid of a 5x loop.The tip fracture surface is at about 45 degrees relative to the driver's longitudinal axis.It is not clear if the failure is solely due to the loading conditions applied in an attempt to remove a well fixed screw, if combined torsional and bending moments were applied that caused the failure, and/or if prior use damage existed that culminated in the subsequent failure.Review of device history records found (b)(4) of lot 0047it were released for distribution on 10/22/2013 with no deviation or anomalies that would related to the reported event.Complaint history review back to the date of manufacture found this to be the only report of this nature for the reported lot.Further review did not identify a trend for reports of this nature for the reported part number.No corrective actions are being recommended since the exact root cause could not be determined, the failure does not appear to be manufacturing related, and there was not trend identified.
