Event Description

It was reported that approximately 15 months after installation, the patient presented to the surgeon with pain.X-rays were taken and the surgeon saw signs that the tulip of the pedicle screw at left l-3 detached from the screw shank.It appeared that the pedicle screw at right l-3 was also broken, as well as the rod between the l-3 and l-4 levels.A revision surgery was performed to remove and replace the implants.There were a total of two rods and four pedicle screws removed; it is not yet clear which rod and pedicle screws are broken.

Manufacturer Narrative

Additional information in implant date, device manufacture date, and evaluation codes: method codes.The device was not returned so an evaluation could not be performed and no conclusions could be drawn.A review of the manufacturing records did not identify any issues which may have contributed to this event.The labeling was reviewed and found to contain information regarding post-operative expectations.

Manufacturer Narrative

Current information is insufficient to permit a valid conclusion about the cause of this event.A follow up report will be sent upon completion of the device evaluation.

Manufacturer Narrative

The returned screw was evaluated.The tulip was found to have disassembled form the threaded shaft; the complaint is confirmed.The top of the threaded shaft was found to be deformed which caused the od to measure undersized while the mating hole within the tulip was found to be deformed which caused the id to measure oversized.Both dimensions were confirmed to meet specifications upon manufacturing.The cause is likely attributed to a large constant force which was exerted upon the head of the left l3 pedicle screw for it to work its way through the hole of the tulip head by progressively shaving off a ring of titanium alloy from the round screw head and by progressively enlarging the hole in the titanium alloy tulip head.
