Event or Problem Description
Information was received from healthcare provider (hcp) via a manufacturer representative regarding a driver used on patient having open lumbar fusion therapy for compression fracture.It was reported that the screw was not fully inserted and had to be removed and replaced.Additionally, there were repeated insertions of pelvic screws due to the drivers breaking.The tips of the drivers sheared off before the screw was fully inserted.Unfortunately, the tip was now in the screw head and could not be advanced so the screw had to removed and replaced with a new one.The pliers didn't work and the spring was jacked up.There was no patient symptoms reported.There was a delay of less than 60 minutes in overall procedure.There were no further complications reported regarding the event.
