Summary:Methods and devices are provided for passively locking a bone screw within a bone plate. In particular, the methods and devices allow a bone screw to be locked within a thru-hole in a bone plate without requiring any additional locking steps. In an exemplary embodiment, an annular feature is provided in a thru-hole of a bone plate, or in a bushing that is disposed within a thru-hole of a bone plate, for engaging a bone screw. The annular feature can be configured such that it allows the bone screw to be inserted through the thru-hole at various insertion angles while still being effective to prevent back-out of the bone screw, thereby locking the screw to the plate.
