Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional information: h3, h6 (methods, results, conclusions).The complaint is unconfirmed for one path finder nxt screw for the reported failure of stripped during implantation but confirmed for damaged tulip head.Visual inspection reveals the screw is deformed with the shaft being disconnected from the tulip.The screw is intact but the top of the tulip is visibly damaged (stripped thread at top of the tulip head).The device was likely conforming when it left zimmer biomet's control.Currently, no action is recommended.
