摘要：
A bone plate assembly includes a plate, at least one bushing, and at least one bone screw. The bushing is positioned within a through hole of the plate. The bushing and screw are configured to engage each other to inhibit the screw from backing out. The screw includes a visual indicator surface that is visible to the operator during insertion of the screw through the bushing and plate. The bushing is configured to cover at least a portion of the visual indicator surface to show when the bushing and screw are properly engaged to inhibit backout of the screw.
