Schematic showing how the lateral plate migration occurred. A, vertical loading of the fusion segment is converted to the horizontal loading of the lateral plate and screws because of the specific angle between the screws and the plate. B, When the cage subsidence occurs, the horizontal loading exceeds the pullout strength of the screws, resulting in the change of angle between screws and the migration of lateral plate and screws
