Manufacturer Narrative

Review of the device history records revealed no manufacturing, processing or design related irregularities.The trestle luxe plate was found to be properly manufactured and released in accordance with the device master record.Visual inspection found posterior damage to one of the thru holes where the screw passed completely thru the plate.Previous engineering investigation determined that this type of occurrence is the results of over angulation of the anchoring plate screw.Both the surgical technique (lit-84315) and instructions for use (ins-048) state; the surgeon must take great care to properly position bone screw holes when using the variable drill guide and self-centering awl.Excessively converging hole patterns may prohibit proper seating of the bone screws.Hole patterns angled beyond 9° may prohibit proper seating.
