摘要：
Internal fixation devices are provided that include a plate having a rotatable screw lock mounted in a recess of the plate. The screw lock has a lock head including a laterally extending flange that has an outer edge that is below the upper surface of the plate. In a locked position, a portion of the upper surface of the plate covers at least a part of the lock head to reduce the likelihood of the screw lock being pushed off the plate. Further, in a locked position, the laterally extending flange obstructs passage of a screw through a corresponding screw hole. Such obstruction hinders screw migration.
