Event Description

It was reported that a screw disassembled during surgery.It was removed and an alternative screw was used to complete the procedure.There were no reports of patient impacts associated with this event.

Manufacturer Narrative

The returned screw was evaluated.The tulip and swivel ring were confirmed to have disassembled from the screw shaft.The swivel ring was deformed in a manner consistent with tightening and later loosening of the mating closure top and rod within the tulip.This deformation allows the tulip and swivel ring to disassemble from the screw shaft as the screw is manipulated during removal or reuse.A review of the manufacturing records did not identify any issues which would have contributed to this event.
