One of two distal prongs of the facet locator appeared to have been broken off because the existing rod & screw construct hindered the deployment of the instrument.In doing so, one of the prongs may have gotten caught up on the screw, set screw, and rod interface causing it to break off upon impaction.It is believed the prong is lodged next to the existing construct as it could not be found with imaging.As per the representative the surgeon was using excessive force malleting the facet locator against an existing construct witch led to the instrument failure.
